Description

The present invention relates to a stick feeder that supplies electronic components from a stick, and an electronic component mounting machine that includes the stick feeder.

The stick feeder is detachably arranged on the device pallet of the electronic component mounting machine. The stick feeder is equipped with multiple sticks. The stick contains a plurality of electronic components. The electronic component is pushed out of the stick by the pusher. The extruded electronic component is conveyed to a predetermined mounting coordinate of the substrate by the suction nozzle of the electronic component mounting machine. A stick (empty stick) from which all electronic components are extruded falls in a predetermined drop passage due to its own weight. The dropped empty sticks are stacked on the upper surface of the accommodating member.

Japanese Unexamined Patent Publication No. 8-139491

However, when falling down the fall passage, an empty stick may get caught in the middle. In this case, the operator must manually remove the empty stick from the drop passage and place it on the accommodating member. Therefore, it is complicated.

In this regard, Patent Document 1 discloses an empty magazine collecting device in which a plurality of abutting members are arranged in a drop passage of an empty magazine. The plurality of abutting members are arranged on both sides in the horizontal direction with the drop passage in between. An altitude difference is set between one abutting member in the horizontal direction (first abutting member) and the other abutting member in the horizontal direction (second abutting member). When the empty magazine falls down the fall passage, it first collides with the first abutting member and then with the second abutting member. Therefore, the falling speed of the magazine can be reduced. However, in the case of the empty magazine collecting device described in the same document, the first abutting member and the second abutting member are alternately arranged in the vertical direction on both sides of the drop passage in the horizontal direction. Therefore, the horizontal width of the fall passage becomes wide.

In the device palette, a plurality of stick feeders are arranged side by side in the horizontal direction. Therefore, there is a limit to the placement space allocated to a single stick feeder. If the stick feeder with the empty magazine collection device described in the same document is arranged on the device pallet, a large arrangement space is required because the horizontal width of the drop passage is wide. Therefore, the space for arranging other stick feeders becomes small. Note that Patent Document 1 does not describe that an empty magazine is caught in the fall passage.

Therefore, an object of the present invention is to provide a stick feeder in which an empty stick is unlikely to be caught in the middle when falling down a drop passage, and an electronic component mounting machine provided with the stick feeder.

In order to solve the above problems, the stick feeder of the present invention is a stick feeder that supplies the electronic components from a stick accommodating a plurality of electronic components, and drops and discharges the empty stick after the electronic components are supplied. The electronic component mounting machine is provided with a guide portion for partitioning a drop passage into which the stick falls, and a protrusion arranged on an inner surface on one side in the width direction of the fall passage so that the falling stick can come into contact with the guide portion. It is characterized in that it is detachably arranged in the arrangement space of the feeder mounting portion.

A protrusion is arranged on the inner surface of one side of the fall passage in the width direction. Therefore, when falling down the fall passage, the empty stick tends to come into contact with the protrusion. When the empty stick touches the protrusion, the empty stick tilts. Therefore, the empty stick is less likely to get caught in the fall passage.

It is a top view of the front side part of the electronic component mounting machine which is one Embodiment of this invention. It is a front-back partial sectional view of the stick feeder which is one Embodiment of this invention. FIG. 2 is a sectional view taken along the line III-III in FIG. It is a left-right cross-sectional view of a stick feeder without a protrusion.

Hereinafter, embodiments of the stick feeder and the electronic component mounting machine of the present invention will be described.

First, the configuration of the electronic component mounting machine of this embodiment will be described. In the following figures, the left-right direction corresponds to the "width direction of the falling passage" and the "X direction" of the present invention, and the front-rear direction corresponds to the "Y direction" of the present invention. FIG. 1 shows a top view of the front side portion of the electronic component mounting machine of the present embodiment. As shown in FIG. 1, the electronic component mounting machine 9 includes a device pallet 90 and an XY robot 91. The device pallet 90 is arranged on the front side portion of the electronic component mounting machine 9. The device pallet 90 is included in the concept of the "feeder mounting portion" of the present invention. On the upper surface of the device pallet 90, a plurality of arrangement spaces A are set side by side in the left-right direction. A stick feeder 1 is arranged in each of the plurality of arrangement spaces A. As described above, a plurality of stick feeders 1 are arranged side by side in the left-right direction on the device palette 90.

The XY robot 91 includes a Y-axis guide rail 910, a Y-axis slider 911, an X-axis guide rail 912, a mounting head 913, and a suction nozzle 914.

The Y-axis slider 911 is movable in the front-rear direction along the Y-axis guide rail 910 (suspended). The X-axis guide rail 912 is arranged on the Y-axis slider 911. The mounting head 913 can move in the left-right direction along the X-axis guide rail 912. The suction nozzle 914 can project downward with respect to the mounting head 913. That is, the suction nozzle 914 can move in the front-back, left-right, up-down directions. The suction nozzle 914 can convey the electronic component 25 from the take-out position B of the stick feeder 1 to a predetermined mounting coordinate of the substrate (not shown).

<Structure of stick feeder>
Next, the configuration of the stick feeder 1 of the present embodiment will be described. FIG. 2 shows a partial cross-sectional view of the stick feeder of the present embodiment in the front-rear direction. FIG. 3 shows a sectional view in the direction III-III of FIG. As shown in FIGS. 2 and 3, the stick feeder 1 includes a feeder main body 2, a transport path member 3, a pair of guide walls 4, a stick accommodating portion 5, a standby stick support portion 6, and a stick support portion used. 7, an empty stick collecting section 8, six fixing members 20, a third case 21, a component extrusion section 22, a cable case 23, and a wiring case 24 are provided.

The feeder main body 2 is detachably attached to the arrangement space A of the device pallet 90. The feeder body 2 is electrically connected to the device pallet 90, that is, the electronic component mounting machine 9. A control device (not shown), a drive mechanism (not shown) for the component extrusion unit 22 described later, and the like are arranged on the feeder main body 2.

The transport path member 3 includes a component receiver (take-out position setting member) 30 and a chute (transport path partition member) 31. The component receiver 30 is arranged on the upper surface of the feeder main body 2. The take-out position B is set in the component receiver 30. The chute 31 is arranged on the upper surface of the feeder main body 2. The chute 31 is connected to the front side of the component receiver 30. The chute 31 has a square tubular shape extending in the front-rear direction. A transport path for the electronic component 25 is defined inside the chute 31.

The pair of guide walls 4 are arranged on the front side of the feeder main body 2. The pair of guide walls 4 are arranged so as to face each other in the left-right direction, separated by a predetermined interval. The pair of guide walls 4 include a first wall 40 and a second wall 41, respectively. The first wall 40 extends from the front end of the feeder main body 2 (the front end of the device pallet 90) to the front side. A guide hole 400 is provided in the first wall 40. The guide hole 400 has a long hole shape that is long in the front-rear direction. The second wall 41 is connected to the front side of the first wall 40. Three fixing holes 410 are formed in the second wall 41. The three fixing holes 410 are arranged in the front-rear direction at predetermined intervals.

Each of the six fixing members 20 includes a bolt 200 and a washer 201. Of the six fixing members 20, three fixing members 20 are arranged on the left guide wall 4, and the remaining three fixing members 20 are arranged on the right guide wall 4.

In the guide wall 4 on the right side, the fixing member 20 is fixed to the fixing hole 410. Specifically, as shown in FIG. 3, the bolt 200 has a washer 201 and a guide hole from the right side (outside when viewed from the fall passage D described later) to the left side (inside when viewed from the fall passage D described later). It penetrates 400 and is screwed into the fixing hole 410. The fixing position of the fixing member 20 with respect to the first wall 40 can be adjusted within the range of the length of the guide hole 400 in the front-rear direction. Therefore, the amount of protrusion of the second wall 41 in the front-rear direction with respect to the first wall 40 can be changed. That is, the length of the guide wall 4 in the front-rear direction can be changed. The arrangement of the three fixing members 20 on the left guide wall 4 is symmetrical with the arrangement of the three fixing members 20 on the right guide wall 4.

Hereinafter, among the six bolts 200, the bolt 200 at the center in the left-right direction of the three bolts 200 of the guide wall 4 on the left side is appropriately referred to as a "long-axis bolt 200a". The long shaft bolt 200a has a longer axial length (horizontal length) than the remaining five bolts 200. Therefore, the long-axis bolt 200a protrudes from the left surface of the second wall 41 (inner surface on one side in the width direction of the fall passage D) to the left side (inside) by the amount of protrusion Ma. The long shaft bolt 200a is included in the concept of "fixing tool" and "protrusion" of the present invention.

As shown in FIG. 3, the cable case 23 is arranged on the left side of the second wall 41 on the right side. The cable cases 23 are arranged below the fixing holes 410 at predetermined intervals. Inside the cable case 23, a pusher cable 221 of a component extrusion portion 22, which will be described later, is inserted. The wiring case 24 is arranged on the right side of the second wall 41 on the left side (inner surface on one side in the width direction of the fall passage D). The wiring cases 24 are arranged below the fixing holes 410 at predetermined intervals. Wiring (wiring for members in the third case 21, which will be described later) 240 is inserted inside the wiring case 24.

The stick accommodating portion 5 includes a first case 50 and a second case 51. A plurality of sticks (parts accommodating members) 26 are accommodated in the stick accommodating portion 5. The stick 26 has a long square tube shape in the front-rear direction. Inside the stick 26, a predetermined number of electronic components 25 are housed side by side in the front-rear direction. The first case 50 is arranged above the pair of first walls 40. As shown in FIG. 1, the first case 50 holds the rear end of the stick 26. A first opening 500 is provided at the lower end of the first case 50. The second case 51 is arranged above the pair of second walls 41. The second case 51 is arranged on the front side of the first case 50 at a predetermined interval. As shown in FIG. 1, the second case 51 holds the front end of the stick 26. A second opening 510 is provided at the lower end of the second case 51. A waiting space E and a used space F are partitioned between the first case 50 and the second case 51. The used space F is set at the bottom. A stick 26 in use (supplying the electronic component 25) is arranged in the use space F. The standby space E is set above the used space F. In the standby space E, a plurality of sticks 26 before use are stacked in several stages.

The standby stick support portion 6 is arranged between the used space F and the standby space E. The standby stick support portion 6 includes a first pin (first support member) 60 and a second pin (second support member) 61. The first pin 60 can move forward and backward from the rear side through the first opening 500 with respect to the front side space (internal space) of the first case 50. The second pin 61 can move forward and backward from the front side with respect to the rear side space (internal space) of the second case 51 via the second opening 510. The first pin 60 and the second pin 61 are each driven by a control device of the feeder main body 2 via an actuator (not shown, for example, a motor, a solenoid, a hydraulic mechanism, a pneumatic mechanism, etc.). The control device sets the positions of the first pin 60 and the second pin 61 as the support position (the position where the first pin 60 and the second pin 61 have entered the internal space of the stick accommodating portion 5) Na and the release position (first). The pin 60 and the second pin 61 can be switched to (position) Nb where the stick accommodating portion 5 exits from the internal space. At the support position Na, the first pin 60 and the second pin 61 support the plurality of sticks 26 in the standby space E from below.

The used stick support portion 7 is arranged below the used space F. The stick support portion 7 used includes a first stopper (first support member) 70 and a second stopper (second support member) 71. When viewed from above, the first stopper 70 can move forward and backward from the rear side with respect to the front side space (internal space) of the first case 50 via the first opening 500. The second stopper 71 is arranged in the second opening 510 of the second case 51. The second stopper 71 is fixed to the third case 21, which will be described later. The first stopper 70 is driven by the control device of the feeder main body 2 via an actuator (not shown, for example, a motor, a solenoid, a hydraulic mechanism, a pneumatic mechanism, etc.). The control device sets the position of the first stopper 70 as the support position (the position where the first stopper 70 enters the internal space of the stick accommodating portion 5 when viewed from above) Pa and the release position (first when viewed from above). It is possible to switch to (position) Pb where the stopper 70 exits from the internal space of the stick accommodating portion 5. At the support position Pa, the first stopper 70 and the second stopper 71 support the stick 26 of the used space F from below.

The third case 21 is arranged on the front side of the second case 51 and on the upper side of the pair of second walls 41. The component extrusion unit 22 includes a pusher 220 and a pusher cable 221. The pusher 220 can move forward and backward from the front side with respect to the transport path inside the used space F (specifically, the inside of the stick 26 arranged in the used space F) and the inside of the chute 31 via the rear wall of the third case 21. Is. The pusher cable 221 connects the pusher 220 and the feeder main body 2 via the cable case 23. The pusher cable 221 drives the pusher 220.

The empty stick collecting units 8 are arranged below the pair of guide walls 4 at predetermined intervals. The empty stick collecting unit 8 includes a first stick receiver 80 and a second stick receiver 81. The first stick receiver 80 is suspended from the first wall 40 via a chain 82. The second stick receiver 81 is suspended from the second wall 41 via the chain 82.

<Fall passage>
Next, the fall passage D partitioned by the stick feeder 1 of the present embodiment will be described. As shown in FIGS. 2 and 3, the drop passage D is partitioned between the upper use space F and the lower empty stick collection unit 8. The drop passage D includes a reference portion Da and a narrow portion Db. The reference portion Da is arranged between the pair of second walls 41. A long-axis bolt 200a protrudes from the right side of the reference portion Da.

The narrow portion Db is arranged between the wiring case 24 on the left side and the cable case 23 on the right side. The narrow portion Db is arranged below the reference portion Da at a predetermined interval. The width of the narrow portion Db in the horizontal direction is the minimum in the total length of the fall passage D in the vertical direction. An altitude difference L is set between the long shaft bolt 200a and the narrow portion Db. The wiring case 24 projects from the right side (inner surface) of the second wall 41 on the left side to the right side (inside). The cable case 23 projects from the left surface (inner surface) of the second wall 41 on the right side to the left side (inside). Therefore, the width of the narrow portion Db is narrower in the left-right direction than that of the reference portion Da. The protruding amount Ma of the long shaft bolt 200a is larger than the protruding amount Mb of the cable case 23.

The length of the fall passage D in the front-rear direction can be adjusted according to the length of the stick 26 in the front-rear direction. That is, as described above, the second wall 41 can move to the front side with respect to the first wall 40. Therefore, the movable side with respect to the fixed side member (feeder body 2, component receiver 30, chute 31, first wall 40, first case 50, first pin 60, first stopper 70, first stick receiver 80). The members (second wall 41, second case 51, fixing member 20, third case 21, cable case 23, wiring case 24, second pin 61, second stopper 71, second stick receiver 81) move to the front side. It is possible. Therefore, the length of each space (fall passage D, standby space E, used space F) in the front-rear direction can be adjusted according to the length in the front-rear direction of the stick 26.

<Movement of stick feeder>
Next, the movement of the stick feeder 1 of the present embodiment will be described. The control device of the stick feeder 1 executes a component extrusion step, an empty stick drop step, and a standby stick drop step.

In the component extrusion step, the control device of the feeder body 2 pushes out a plurality of electronic components 25 from the stick 26 in the used space F by the pusher 220. The plurality of extruded electronic components 25 arrive at the component receiver 30 (take-out position B) one by one via the transport path of the chute 31. The electronic component 25 that has arrived at the take-out position B is taken out by the suction nozzle 914. The taken-out electronic component 25 is mounted at predetermined mounting coordinates of the substrate (not shown).

In the empty stick dropping step, the empty stick 26 is collected by the empty stick collecting unit 8. That is, as shown in FIG. 2, when the stick 26 in the used space F is emptied, the control device of the feeder main body 2 supports the first stopper 70 along the guide groove 310 on the lower wall of the chute 31. Switch from Pa to the release position Pb. Therefore, the rear end of the stick 26 falls from the first stopper 70 due to its own weight. On the other hand, the front end of the stick 26 is supported by the upper surface 710 of the second stopper 71. The upper surface 710 is set to have an inclination that descends toward the rear side (first stopper 70 side). Therefore, as the rear end of the stick 26 falls, the front end of the stick 26 also slides down from the upper surface 710 due to its own weight. In this way, the empty stick 26 enters the fall passage D by its own weight.

The first pin 60 and the second pin 61 are set at the support position Na. Therefore, even if the sticks 26 in the used space F move (even if they fall) to the fall passage D, the plurality of sticks 26 in the standby space E are immobile.

FIG. 4 shows a left-right cross-sectional view of a stick feeder (hereinafter, referred to as a “protrusionless stick feeder”) in which a normal bolt is arranged instead of a long-axis bolt. Note that FIG. 4 corresponds to FIG.

As shown in FIG. 4, in the case of the stick feeder 1a without protrusions, the bolt 200 does not protrude into the drop passage D. Therefore, the empty stick 26 passes through the reference portion Da without delay. However, the horizontal width of the stick 26 (specifically, the horizontal width of the stick 26 in the used space F) Dc is slightly shorter than the narrow portion Db. Therefore, depending on the drop path and the drop posture of the stick 26, the stick 26 may come into contact with the cable case 23 when passing through the narrow portion Db. Therefore, the stick 26 tilts to the lower left side with the radius of curvature Rb around the contact position Hb. Therefore, the stick 26 comes into contact with the wiring case 24. Of course, the stick 26 may first come into contact with the wiring case 24 and then with the cable case 23. As described above, in the case of the stick feeder 1a without protrusions, the empty stick 26 is likely to be caught in the narrow portion Db.

On the other hand, as shown in FIG. 3, in the case of the stick feeder 1 of the present embodiment, the long-axis bolt 200a protrudes into the drop passage D. As described above, the protruding amount Ma of the long shaft bolt 200a is larger than the protruding amount Mb of the cable case 23. Therefore, when passing through the reference portion Da, the stick 26 comes into contact with the long shaft bolt 200a. Therefore, the stick 26 tilts to the lower left side with the radius of curvature Ra about the contact position Ha. Here, when viewed from the front side, the distance ra between the center of gravity G of the stick 26 (arranged at the center in the left-right direction of the fall passage D) and the contact position Ha at the time of contact with the long-axis bolt 200a shown in FIG. It is smaller than the distance rb between the center of gravity G of the stick 26 and the contact position Hb when the cable case 23 is contacted as shown in FIG. Therefore, the radius of curvature Ra shown in FIG. 3 is smaller than the radius of curvature Rb shown in FIG. That is, the stick 26 shown in FIG. 3 tilts smaller than the stick 26 shown in FIG. Therefore, as shown in FIG. 3, the stick 26 does not come into contact with the wiring case 24. As described above, in the case of the stick feeder 1 of the present embodiment, the empty stick 26 passes through the narrow portion Db without delay. The stick 26 that has passed through the narrow portion Db is housed in the empty stick collecting portion 8.

In the standby stick drop step, the stick 26 at the bottom of the standby space E is moved to the used space F. That is, as shown in FIG. 2, after the empty stick 26 has fallen, the control device of the feeder main body 2 moves the first stopper 70 from the release position Pb along the guide groove 310 on the lower wall of the chute 31. Switch to the support position Pa. Further, the control device of the feeder main body 2 switches the first pin 60 and the second pin 61 from the support position Na to the release position Nb. Therefore, the stick 26 at the bottom of the standby space E falls into the used space F. Further, the remaining sticks 26 in the standby space E fall one step at a time (the length of the sticks 26 in the vertical direction).

<Effect>
Next, the effects of the stick feeder 1 and the electronic component mounting machine 9 of the present embodiment will be described. As shown in FIG. 3, a long-axis bolt 200a is arranged on the inner surface on the right side (one side in the width direction) of the drop passage D. Therefore, when the drop passage D is dropped, the empty stick 26 tends to come into contact with the long shaft bolt 200a. When the empty stick 26 comes into contact with the long shaft bolt 200a, the empty stick 26 tilts. Therefore, the empty stick 26 is less likely to be caught in the fall passage D.

Further, as shown in FIG. 3, in the used space F, the stick 26 is arranged so that the long sides (both upper and lower sides) of the cross section in the left-right direction face the left-right direction, that is, the width direction of the fall passage D. Therefore, if the stick 26 falls down the fall passage D in this posture, it is likely to be caught in the fall passage D. However, a long shaft bolt 200a is arranged in the drop passage D. Therefore, when the drop passage D is dropped, the empty stick 26 tends to come into contact with the long shaft bolt 200a. When the empty stick 26 comes into contact with the long shaft bolt 200a, the empty stick 26 tilts. Therefore, the long sides of the cross section of the stick 26 in the left-right direction (both upper and lower sides in the used space F) tend to be oriented in a direction (for example, in the vertical direction) intersecting with the width direction of the fall passage D. Therefore, the empty stick 26 is less likely to be caught in the fall passage D.

Further, when falling down the fall passage D, the empty stick 26 first passes through the reference portion Da and then through the narrow portion Db. The long shaft bolt 200a is arranged on the reference portion Da. Therefore, when passing through the reference portion Da, the empty stick 26 tends to come into contact with the long shaft bolt 200a. When the empty stick 26 comes into contact with the protrusion, the empty stick 26 tilts. Therefore, the empty stick 26 is less likely to be caught in the narrow portion Db.

Further, when viewed from the front side, the distance ra shown in FIG. 3 is smaller than the distance rb shown in FIG. Therefore, the radius of curvature Ra shown in FIG. 3 is smaller than the radius of curvature Rb shown in FIG. That is, the stick 26 shown in FIG. 3 tilts smaller than the stick 26 shown in FIG. Therefore, the empty stick 26 is less likely to be caught in the narrow portion Db.

Further, when the empty stick 26 comes into contact with the long shaft bolt 200a when passing through the reference portion Da, the upper surface of the empty stick 26 when passing through the narrow portion Db is relative to the projected area of the upper surface of the stick 26 in the used space F. The projected area can be reduced. Therefore, the empty stick 26 is less likely to be caught in the narrow portion Db.

Further, when the empty stick 26 comes into contact with the long shaft bolt 200a when passing through the reference portion Da, the empty stick 26 can be tilted or rotated. Therefore, the empty stick 26 tends to take a posture suitable for passing through the narrow portion Db. Therefore, the empty stick 26 is less likely to be caught in the narrow portion Db.

Further, the stick feeder 1a without protrusions shown in FIG. 4 can be changed to the stick feeder 1 of the present embodiment shown in FIG. 3 by simply replacing the bolt 200 shown in FIG. 4 with the long shaft bolt 200a shown in FIG. Can be done. That is, it is possible to prevent the empty stick 26 from being caught in the narrow portion Db by a simple operation of replacing the bolt.

By the way, if there is no limitation on the arrangement space A of the stick feeder 1 in the device pallet 90, if the narrow portion Db is set sufficiently larger than the horizontal width Dc of the stick 26 shown in FIG. 4, it is empty. It is possible to prevent the stick 26 from being caught in the narrow portion Db. However, in the device pallet 90, a plurality of stick feeders 1 are arranged side by side in the left-right direction (board transfer direction). Therefore, the arrangement space A allocated to the single stick feeder 1 is limited. Further, the horizontal width of the fall passage D is inevitably smaller than the horizontal width of the arrangement space A. Therefore, it is difficult to set the narrow portion Db to a large size. In this regard, according to the stick feeder 1 of the present embodiment, as shown in FIGS. 3 and 4, the width of the preset arrangement space A in the left-right direction, in other words, the width of the fall passage D in the left-right direction is not expanded. , It is possible to prevent the empty stick 26 from being caught in the narrow portion Db.

Further, the protrusion amount Ma of the long shaft bolt (projection) 200a is larger than the protrusion amount Mb of the cable case (a member arranged on the guide wall 4 on the protrusion side among the members for partitioning the narrow portion Db) 23. large. Therefore, the stick 26, which falls in the path of contact with the cable case 23, can always be brought into contact with the long shaft bolt 200a.

<Others>
The embodiment of the stick feeder and the electronic component mounting machine of the present invention has been described above. However, the embodiment is not particularly limited to the above embodiment. It is also possible to carry out in various modified forms and improved forms that can be performed by those skilled in the art.

The guide wall 4 may be made of a single component. It is sufficient that the fall passage D is set between the pair of guide walls 4. The shape of the protrusion is not particularly limited. Bolts, pins, clips and the like may be used as protrusions. Further, the cable case 23 and the wiring case 24 may be used as protrusions. Further, a protrusion may be formed integrally with the inner surface of the guide wall 4. Further, the protrusion may be arranged on the inner surface on the left side (one side in the width direction) of the drop passage D. A plurality of protrusions may be arranged side by side in the vertical direction or the front-rear direction. Further, the protruding amount Ma of the long shaft bolt 200a may be smaller than the protruding amount Mb of the cable case 23.

Further, the width in the left-right direction of the fall passage D shown in FIG. 3 may be constant over the entire length of the fall passage D. That is, the reference portion Da and the narrow portion Db may not be set in the fall passage D. Even in this case, the stick 26 can be tilted by arranging the long-axis bolt 200a in the drop passage D.

The altitude difference L between the long-axis bolt 200a (projection) shown in FIG. 3 and the narrow portion Db is not particularly limited. Preferably, the left end (tip) of the long shaft bolt 200a (protrusion) and the wiring case (a member of the members partitioning the narrow portion Db, which is arranged on the guide wall 4 on the opposite side of the protrusion) 24. It suffices if a distance exceeding the radius of curvature Ra can be secured between them. In this way, it is possible to prevent the empty stick 26 from being caught in the narrow portion Db.

The type of feeder arranged on the device palette 90 is not particularly limited. For example, the stick feeder 1 and the tape feeder or tray feeder may be mixedly mounted. The X direction does not have to coincide with the substrate transport direction (horizontal direction in FIG. 1). For example, the front-rear direction in FIG. 1 may be the X direction.

The width in the left-right direction of the narrow portion Db shown in FIG. 3 does not have to be the minimum in the total length in the vertical direction of the fall passage D. If there is a portion of the fall passage D whose width in the left-right direction is narrowed from the upper side to the lower side, the reference portion Da can be set on the upper side and the narrow portion Db can be set on the lower side. The number of reference portions Da and narrow portions Db is not particularly limited.
