Description

  The present invention relates to an electronic component supply apparatus that handles electronic components having leads.

The electronic component mounting apparatus picks up the electronic component supplied from the electronic component supply device with a nozzle mounted on the head, and transports the electronic component to a target position on the substrate by the head for mounting.
By the way, as for the electronic component with a lead, the lead is extended toward the lower side from the left and right side end portions of the electronic component. The electronic components with leads are accommodated in a state in which the internal hollow region is arranged in a line in a cylindrically-shaped component accommodating body having a gate shape. The electronic component supply device feeds electronic components from one end of the component container and supplies them to the electronic component mounting device.
The conventional component container has an endless conveyor belt along the direction in which the electronic components are arranged, and the electronic component supply device applies power to the conveyor belt of the component container to feed out the electronic components. (For example, refer to Patent Document 1).

  However, when the electronic components with leads are arranged in a row as described above, the components are easily clogged inside the component container, and the motor that is the conveyance drive source of the conveyance belt in the state where the components are clogged If the driving is continued, there are problems such as heat generation due to the load and wear of power transmission parts.

As a technique for preventing overload when transporting with an endless belt as described above, both ends of the endless belt are stretched with a pair of transport pulleys, and one transport pulley is moved away from the other transport pulley with a spring. Some have a configuration in which tension is applied (for example, see Patent Document 2).
In the above-described configuration, when the conveyance object is inhibited from being conveyed for some reason and a load of a certain level or more is generated, one conveyance pulley moves toward the other conveyance pulley against the tension of the spring. This movement is detected by a sensor and the drive source is stopped to prevent overload.

Japanese Utility Model Publication No. 5-29200 Japanese Patent Laid-Open No. 7-170096

In order to take measures against overload in Patent Document 2, it is essential to provide a conveyor belt in the component housing as in Patent Document 1.
However, since it is common to mount and use a component container of a plurality of electronic components in one electronic component supply device, it is necessary to reduce the cost of the component container suitable for mass production. However, there is a problem that it is difficult to reduce the cost when the conveyor belt is mounted in the component housing.

  An object of the present invention is to reduce an overload of a driving source for transporting an electronic component of an electronic component supply device while reducing a production cost of the component container.

The present invention according to the electronic component supply apparatus
In an electronic component supply device that has a cylindrical component container that accommodates an electronic component therein and supplies the electronic component of the component container to a component delivery position,
A holding portion for holding the component container;
An insertion member that is inserted into the component container, is capable of feeding out the electronic component, and has flexibility;
A drive source for inserting the insertion member into the component container;
A bending detection unit that detects bending generated in the vertical direction by the insertion member in an inserted state in the component container;
And a control unit that performs control to stop the drive source when the deflection detection unit detects a deflection exceeding a specified amount of the insertion member.

  The electronic component supply apparatus may further include a guide unit having a guide path for guiding the electronic component from the component container of the holding unit to the component delivery position on an extension line in the feeding direction of the electronic component. good.

  The electronic component supply device may include a transport unit that sends the electronic component in the guide unit to the component delivery position side.

  The electronic component supply apparatus may further include a component detection unit that detects the presence or absence of an electronic component at the component delivery position, and the control unit detects the electronic component by the component detection unit when the drive source is driven. In addition, the drive source may be stopped.

  Further, in the electronic component supply device, the control unit is configured to stop the drive source when a state in which the deflection detection unit does not detect the deflection of the insertion member has elapsed after the drive source is driven. Also good.

  Moreover, the said electronic component supply apparatus WHEREIN: It is good also as a structure which makes the said bending | flexion detection part the origin sensor of the said insertion member which detects the said insertion member in the one end part side of the said component container.

In the above invention, when the insertion member to be inserted into the component container is grasped due to clogging of the component or the like, the occurrence of the grasping of the insertion member is detected by the deflection detection unit and driven by the flexibility. Stop the source. As a result, it is possible to avoid the occurrence of an overload caused by continuing to drive the drive source while the advance of the insertion member is inhibited.
And since the overload of a drive source is detected from the bending of an insertion member, it becomes unnecessary to equip a component belt in a conventional component container, and a component container can be formed with a simple cylindrical body. For this reason, it becomes possible to achieve cost reduction suitable for mass production of the component container.

In addition, when a guide unit that guides the electronic component from the component container to the component delivery position is provided, the fed-out electronic component can be smoothly guided to the component delivery position.
In particular, when a transport unit that feeds the electronic component in the guide unit to the component delivery position side is provided, it is possible to guide the electronic component that has been delivered more reliably to the component delivery position.

  In addition, when the control unit stops the drive source by detecting the electronic component by the component detection unit, the stop position of the advancing insertion member can be optimized and the electronic component can be sent appropriately.

Further, when the control unit stops the drive source after a certain period of time has elapsed since the drive source is driven and the deflection detection unit does not detect the deflection of the insertion member, the component container is shorter than the guide path of the guide unit. Even if it exists, it becomes possible to send an electronic component appropriately.
That is, when driven by a drive source for a certain period of time, all the electronic components in the component container are fed out to the guide portion, so that the advancement of the insertion member can be appropriately stopped without providing a component detection portion at the component delivery position. Is possible.

  In addition, when the deflection detection unit is an origin sensor, the means for detecting the positioning position of the insertion member that is retracted back and the means for detecting the deflection can be shared, thereby reducing the number of parts and the manufacturing cost. It becomes possible to plan.

[Electronic parts and parts container]
FIG. 2 is a perspective view of the component container 20, and FIG. 3 is a view showing a cross section along the Z direction. As shown in FIG. 3, the electronic component C supplied by the electronic component supply apparatus 10 includes leads C2 that protrude from the left and right side surfaces of the component main body C1 and extend downward. One or more leads C2 are provided on one side.

As shown in FIGS. 2 and 3, the component container 20 is a cylindrical body having a substantially rectangular cross section with both end portions 21 and 22 opened. And as for the component container 20, the outer wall is formed so that the cross-sectional shape of the hollow interior space may become a gate type. Further, by forming a gate-shaped cross section, a ridge 23 is formed on the inner bottom surface over the entire length.
And in the said component container 20, the some electronic component C is accommodated in a line in the state straddling the protruding item | line 23. FIG.

[flame]
As shown in FIG. 1, the frame 80 includes a main body 81 that supports the holding unit 30 and the transport unit 60, and two legs 82 that are provided vertically on the lower side of the main body 81. A total of four height adjustment members 83 (only two are shown in FIG. 1) are provided in each leg portion 82. For this reason, even if the installation location of the electronic component supply apparatus 10 is not completely horizontal, the main body 81 can be leveled by the individual height adjusting members 83.

[Holding part]
As shown in FIG. 1, the holding portion 30 of the component container 20 includes support plates 31 and 32 that are erected facing each other at the upper portion of the main body portion 81 of the frame 80. Are formed with fitting grooves 33 and 34 along the vertical direction in which both end portions 21 and 22 of the component container 20 are gently fitted.
And in the holding | maintenance part 30, the main-body part is made by fitting the both ends 21 and 22 of each component container 20 in the fitting grooves 33 and 34 at the upper end part of each support plate 31 and 32, and dropping down. It can be stacked on top of 81.
Further, the lowermost component housing 20 is supported from below at a predetermined height by first and second support members 71 and 72 of a discharge mechanism 70 described later.

  The support plate 31 is formed with a through hole 35 that faces the opening of the one end 21 of the component container 20 held at the lowermost side. This is for the insertion member 40 inserted into the one end 21 of the lowermost component housing 20 to pass through the support plate 31.

Further, the support plate 32 is formed with a through hole 36 facing the opening of the other end 22 of the component container 20 held at the lowermost side. This is for the plurality of electronic components C pushed out by the insertion member 40 inserted into the component container 20 to pass through the support plate 31.
In addition, the conveyance part 60 is located in the other end part 22 side of the component container 20 hold | maintained at the lowest side of the holding | maintenance part 30 on the extension line along the longitudinal direction of the said component container 20. FIG. Therefore. The electronic component C pushed out from the component container 20 is sent to the transport unit 60 through the through hole 36 of the support plate 32.

[Insert member]
FIG. 4 is a schematic diagram showing the configuration of the insertion member 40 and the drive mechanism 50. The insertion member 40 includes a flat plate-like long metal belt 41 having flexibility, and a pusher 42 that is provided at the tip of the belt and abuts against the electronic component C.
When the insertion member 40 is not used, the metal belt 41 is wound around the drum 51 of the drive mechanism 50 due to its flexibility. Further, the metal belt 41 is curved so that a central portion in the width direction (a direction perpendicular to the longitudinal direction and the thickness direction) is slightly depressed over the entire length. In the state where the insertion member 40 is wound around the drum 51, the bending in the width direction is relaxed and the insertion member 40 can be easily bent along the drum peripheral surface. It is possible to maintain a state of being bent in a straight line and extending straight in the longitudinal direction.
Therefore, as shown in FIG. 5, when the insertion member 40 in which the winding state of the metal belt 41 is unwound is inserted into the component container 20 from one end, the electronic components C aligned in a row due to its rigidity are inserted into the other end. It can be pushed out to the 22 side.

  The pusher 42 abuts on the electronic component C in the component housing 20 when the metal belt 41 is extended, so that the pusher 42 is fed out, so that the material is softer than the metal belt (such as rubber or plastic) so as not to damage the electronic component C. Resin material). It is more desirable to coat the surface with a low friction material so that friction with the surroundings does not occur during insertion.

[Drive mechanism]
As shown in FIGS. 1 and 4, the drive mechanism 50 is provided on the rear end side of the main body 81 of the frame 80 (the component delivery position P is the front end side).
The drive mechanism 50 includes a drum 51 that winds the insertion member 40 described above, a driven belt pulley 52 that is coupled to the drum 51 on the same shaft and performs interlocking rotation, and the insertion member 40 moves forward and backward along the component housing 20. A feeding motor 53 serving as a driving source for the operation, a main driving belt pulley 54 attached to an output shaft of the feeding motor 53, and a timing belt 55 stretched over the belt pulleys 52 and 54 are provided.

The driven belt pulley 52 has an outer diameter larger than that of the main belt pulley 54, and the rotation of the feeding motor 53 is decelerated and transmitted to the drum 51.
When the drum 51 is rotated in the clockwise direction in FIG. 4 by the feeding motor 53, the insertion member 40 moves forward and is inserted into the component housing 20, and when the drum 51 is rotated in the counterclockwise direction in FIG. The member 40 is wound around the drum 51 and retracted, and is pulled out from the component container 20.

[Origin sensor]
As shown in FIGS. 1 and 4, the insertion member 40 has an origin (a standby position when not in use) where the tip pusher 42 is located in front of the through hole 35 of the support plate 31. An origin sensor (deflection detection unit) 56 as a detection unit is provided inside the through hole 35 serving as a position.
The origin sensor (deflection detection unit) 56 includes a light source that projects light onto a detection target, a light receiving element that receives reflected light from the light projection, and an optical system that is provided separately for the light source and the light receiving element. The light source is provided so as to project downward.
When the insertion member 40 is moving forward, as shown in FIG. 6A, the metal belt 41 or the pusher 42 is projected and the reflected light is received, and the sensor output of the origin sensor 56 is inserted. There is a member (ON state).
Further, when the insertion member 40 is retracted from the origin sensor 56, as shown in FIG. 6B, the metal belt 41 and the pusher 42 are out of the light projecting position, so that the reflected light is not received. The sensor output of the origin sensor 56 is no insertion member (OFF state).
Based on these detections, the control unit 90, which will be described later, stops the feeding motor 53 when the origin sensor 56 is switched from the ON state to the OFF state when the feeding member 53 is wound up by the feeding motor 53. Control is performed to stop 40 at the origin position.

The origin sensor 56 has a distance range d that can be detected in the light projection direction (vertical vertical direction) from the sensor by the optical system, and the metal belt 41 or the pusher 42 is out of the distance range d. In this case, even if the light is projected from the light source, the reflected light is not received by the light receiving element, and the sensor output of the origin sensor 56 has no insertion member (OFF state).
For example, when a series of electronic components C are fed out from the component container 20, the electronic components C are stacked and the insertion member 40 cannot move forward, and the feeding motor 53 continues to drive as shown in FIG. 6C. Thus, each part of the metal belt 41 bends in the vertical direction due to its flexibility.
As a result, the metal belt 41 deviates from the detectable distance range d of the origin sensor 56, and the output of the origin sensor 56 has no insertion member (OFF state).

Therefore, the control unit 90 detects the occurrence of an overload state of the feeding motor 53 when the insertion member 40 cannot move forward by using the detection range characteristic of the origin sensor 56 and the flexibility of the insertion member 40. ing. That is, when the output of the origin sensor 56 is turned off while the feeding motor 53 is driven in the direction in which the insertion member 40 moves forward, the control unit 90 assumes that the overload state of the feeding motor 53 has occurred. The emergency stop of the motor 53 is performed.
Thus, the origin sensor 56 performs both the origin position detection of the insertion member 40 and the detection of the overload state of the feeding motor 53.

[Discharge mechanism]
7 and 8 are schematic configuration diagrams showing the discharging operation of the discharging mechanism 70 in order.
As shown in FIGS. 1, 7, and 8, the discharge mechanism 70 is disposed below the holding unit 30 in the frame 80.
The discharge mechanism 70 includes first and second support members 71 and 72 that individually mount and support the bottom surfaces of both end portions of the lowermost component housing 20 of the holding unit 30, and the holding unit 30. Are provided with third and fourth support members 73 and 74 that can be individually inserted and supported in the openings at both ends of the second component housing 20 from the bottom.
In addition, the lower portion of the main body 81 of the frame 80 and the holding portion 30 is formed with an opening (not shown) through which the component container 20 can be dropped, and a drop is formed below the opening. A discharge slope 75 for receiving the component container 20 to be discharged and discharging it to the rear is attached.

Each of the support members 71 to 74 can be switched between holding and releasing the component container by moving forward and backward along the longitudinal direction of the component container 20 by actuators 71a to 74a (see FIG. 9) such as solenoids. It has become. In addition, the first and second support members 73 and 74 are also provided with actuators 71b and 72b (see FIG. 9) for moving up and down, and are the second from the bottom after the lowermost component container 20 is discharged. It is possible to perform an operation for receiving the component container 20.
Hereinafter, the operation of dropping and discharging the lowermost component container 20 will be described in order.

During the normal operation of feeding out the electronic component C, the first and second support members 71 and 72 are in a supporting state and located below the lowermost component housing 20, and the third and fourth. The support members 73 and 74 are inserted into both end portions of the second component housing 20 from the bottom (FIG. 7A).
Next, when the first and second support members 71 and 72 are retracted and separated from the lower side of the lowermost component housing 20, the component housing 20 falls and slides on the discharge slope 75 to the outside of the machine. It is discharged (FIG. 7B). Further, the second component container 20 from the bottom and the upper component container 20 are supported by the third and fourth support members 73 and 74 and thus do not fall.

Next, the first and second support members 71 and 72 move forward and return to the support position (the state shown in FIG. 7C). It is made to contact | abut to the bottom face of a part (FIG.7 (D)).
Then, the third and fourth support members 73 and 74 are retracted from the state, and the state of supporting the both end portions of the component housing 20 that is newly at the lowest position is released (FIG. 8A). Only the first and second support members 71 and 72 are in a state of supporting the component housing 20 that is newly lowermost.

Next, the first and second support members 71 and 72 are lowered, and the component housing 20 that is newly at the lowest position is positioned at a height at which the electronic component C can be fed (FIG. 8B). ).
Then, the third and fourth support members 73 and 74 are advanced and inserted into both end portions of the component housing 20 that is newly second from the bottom (FIG. 8C), and the discharging operation is completed.

[Transport section]
As shown in FIG. 1, the conveyance unit 60 vibrates the guide unit 61 having a guide path for guiding the electronic component C from the support plate 32 to the component delivery position P, and the electronic component C in the guide unit 61 with minute vibration. And an excitation mechanism 62.
The guide part 61 has a concave groove that conveys the electronic components C in a row as a guide path, and a convex line having the same cross-sectional shape and dimensions as the convex line 23 of the component container 20 is formed on the inner bottom surface of the concave groove. The guide portion 61 is formed over the entire length. Further, the ridge of the guide portion 61 is formed so as to be close to and communicate with the ridge 23 of the lowermost component housing 20 in the holding portion 30. Further, the ridges 23 of the component container 20 and the ridges of the guide portion 61 are formed so that no step is generated or the ridges of the guide portion 61 are slightly lowered. Further, the protrusions in the guide portion 61 may be chamfered so that the electronic component C is not caught.
Accordingly, each electronic component C fed out from the opening of the other end portion 22 of the component container 20 by the pressing of the insertion member 40 smoothly moves to the guide portion 61 and is conveyed to the component delivery position P.
Further, the total length of the guide portion 61 is set longer than the total length of the component container 20, and it is possible to send out all the electronic components C in the component container 20 into the guide path of the guide portion 61. .

In addition, a component detection sensor 63 as a component detection unit that detects whether an electronic component C exists at the component delivery position P is provided at the component delivery position P in the guide path of the guide unit 61.
This component detection sensor 63 arranges the light source and the light receiving element so as to sandwich the electronic component C in the guide path, and detects the presence of the electronic component C by blocking the light reception of the light receiving element.

  The insertion member 40 is set to a length that does not reach the component delivery position P, and the insertion member 40 is not detected by the component detection sensor 63. The electronic component C pushed out to the guide portion 61 by the insertion member 40 is conveyed to the component delivery position P by a vibration mechanism 62 described later. The insertion member 40 arrives at the leading electronic component C to the component delivery position P when all the electronic components C in one component container 20 are moved to the component delivery position P side in a line. You may set to the length which can be made to do.

  The vibration mechanism 62 vibrates the guide portion 61 to move each electronic component C placed on the ridge forward toward the component delivery position P side. It should be noted that depending on which part of the guide portion 61 is vibrated in which direction and amplitude, the direction in which the electronic component C moves depends on which direction the electronic component C moves forward. The excitation position, the excitation direction, the excitation period, and the excitation amplitude are adjusted so as to perform.

[Control system of electronic component supply device]
FIG. 9 is a block diagram showing a control system of the electronic component supply apparatus 10.
The control unit 90 of the electronic component supply apparatus 10 includes an I / F (interface) 95 and is provided on the rear end side of the frame 80. As shown in FIG. The actuators 71a to 74a, 71b and 72b of the four support members 71 to 74 are connected to each other via a drive circuit (not shown).
The origin sensor 56 and the component detection sensor 63 described above are also connected to the interface 95 of the control unit 90.

The control unit 90 includes a CPU 91 that executes various control programs, a ROM 92 that stores the control programs, a RAM 93 that serves as a work area for various processes by storing various data, and the CPU 91 and various devices. And an operation switch 94 as an input means for various settings and operations.
Further, the operation switch 94 is provided with a notification device such as a display lamp or a buzzer for performing error notification during the component supply operation.
The control unit 90 executes electronic component supply operation control, which will be described below, according to the control program.

FIG. 10 shows the flow of processing of supply operation control executed by the CPU 91 by the control program.
First, the CPU 91 of the control unit 90 monitors whether or not all the electronic components C in the guide unit 61 have been picked up based on the output of the component detection sensor 63 (step S1).
That is, while the electronic component C still remains in the guide portion 61, the vibration is generated when the leading electronic component C is picked up by the electronic component mounting apparatus and the detection output of the component detection sensor 63 becomes no component. As soon as the mechanism 62 is driven, the next electronic component C moves forward and reaches the component delivery position P, and the detection output of the component detection sensor 63 returns to the presence of the component in a short time. However, when the electronic component C does not remain in the guide portion 61, the detection output of the component detection sensor 63 does not return to the presence of the component even when the vibration mechanism 62 is driven. If the detection output of the component detection sensor 63 does not have a component even after a lapse of a certain time after driving, it is determined that there is no electronic component C in the guide portion 61.

If it is determined that all the electronic components C in the guide portion 61 have been picked up, the CPU 91 starts driving the feeding motor 53 (step S3).
As a result, the insertion member 40 that has been waiting at the origin position starts to move forward. Then, when the insertion member 40 moves forward from the origin position, the output of the origin sensor 56 has an insertion member (ON state). Further, the insertion member 40 moves forward to be inserted from the opening of the one end portion 21 of the component housing 20 positioned at the lowermost side, presses all the electronic components C inside, and in order of the transport unit 60. It sends out to the guide part 61.

  Then, the CPU 91 monitors the occurrence of bending of the insertion member 40 from the output of the origin sensor 56 while driving the feeding motor 53 in the forward direction of the insertion member 40 (step S5). The bending of the insertion member 40 is determined by whether or not the output of the origin sensor 56 becomes no insertion member (OFF state) as in the case of FIG. 6C described above.

When determining that the bending of the insertion member 40 has not occurred, the CPU 91 determines whether or not the leading electronic component C has reached the component delivery position P by the component detection sensor 63 (step S7).
As a result, when it is determined that the leading electronic component C has not reached the component delivery position P, the process returns to step S5 and the occurrence of bending of the insertion member 40 is monitored again.
On the other hand, if the arrival of the leading electronic component C at the component delivery position P is detected by the component detection sensor 63, the CPU 91 stops the driving of the feeding motor 53 (step S9). Thereby, all the electronic components C in the lowermost component container 20 are sent to the guide unit 61 of the transport unit 60.
And the drive by reverse rotation of the feeding motor 53 is started, the metal belt 41 is wound up and the insertion member 40 is moved backward (step S11).
Even if the insertion member 40 is retracted, the vibration mechanism 62 is driven, so that the electronic component C is sent to the component delivery position P.

While the insertion member 40 is moving backward, the CPU 91 repeatedly monitors the output of the origin sensor 56 until the return of the origin position (OFF state) is detected (step S13).
Then, when it is detected that the insertion member 40 has returned to the origin position, the CPU 91 stops the reverse rotation drive of the feed motor 53 (step S15).

Next, the CPU 91 controls the actuators 71a, 72a, 71b, 72b of the discharge mechanism 70 to execute the above-described operations of FIGS. It discharges outside (step S17).
Further, the CPU 91 controls the actuators 71a, 72a, 73a, 74a, 71b, 72b of the discharging mechanism 70 to execute the operations shown in FIGS. 7C to 8C, and the next component container 20 Is moved to a position where the electronic component C can be fed (step S19).

On the other hand, when the occurrence of bending of the insertion member 40 is detected in step S5, the CPU 91 stops the driving of the feeding motor 53 (step S21), starts driving in the reverse rotation, and the metal belt 41. And the insertion member 40 is moved backward (step S23).
Then, the CPU 91 continues winding until the origin position return (OFF state) is detected (step S25), and when the origin sensor 56 detects the return (OFF state), the feeding motor 53 is driven to rotate backward. Is stopped (step S27).
Thereafter, when the clogging of components causing the bending of the insertion member 40 is resolved by the operator and a return button (not shown) provided on the operation switch 94 is pressed, the process is returned to step S1.

[Technical effect of parts delivery position]
The electronic component supply apparatus 10 uses the fact that the insertion member 40 to be inserted into the component container 20 is bent due to the clogging of the component, etc., so that the occurrence of the holding of the insertion member 40 is detected by the origin sensor. Detected by 56, the feeding motor 53 is stopped. As a result, it is possible to avoid the occurrence of an overload caused by continuing the driving of the feeding motor 53 when the insertion member 40 cannot move forward.
Then, since the overload of the feeding motor 53 is detected from the bending of the insertion member 40, it is not necessary to equip the inside with a conveyor belt as in the conventional component container, and the component container 20 is simply formed by a cylindrical body. Can be formed. For this reason, it is possible to reduce the cost of the component container 20 suitable for mass production.

  Further, as described above, since the bending of the insertion member 40 is detected by the origin sensor 56 used for positioning the origin of the insertion member 40, the sensor can be shared, the number of parts can be reduced, and the manufacturing cost can be reduced. Can be reduced.

In addition, since the transport unit 60 of the electronic component supply apparatus 10 includes the guide unit 61, all the electronic components C in the component container 20 can be sent into the guide unit 61 at a time. It is possible to reduce the driving frequency.
Moreover, since the conveyance part 60 is provided with the vibration mechanism 62, it is possible to guide the electronic component fed out more reliably to the component delivery position P.

  Further, the control unit 90 stops the feeding motor 53 by detecting the electronic component C by the component detection sensor 63, so that the stop position of the insertion member 40 moving forward can be optimized and the electronic component C can be sent appropriately. It becomes.

[Others]
Although the insertion member 40 includes the metal belt 41 having a width, a flexible wire material may be used instead of the metal belt 41. Moreover, as long as it has a certain amount of rigidity and flexibility, not only a metal but other materials (resin etc.) may be utilized.

  Moreover, it is good also as a structure which is not equipped with the conveyance part 60 in the electronic component supply apparatus 10. FIG. In that case, every time the leading electronic component C is picked up, the operation control is performed so that the insertion member 40 is advanced and the next electronic component C is fed out to the component delivery position P.

Note that the interval between the support plates 31 and 32 described above can be adjusted, and various component containers having different lengths can be stacked on the holding unit 30.
Further, when the component container 20 is short and the electronic component C at the top does not reach the component detection sensor 63 at the component delivery position P even if the insertion member 40 feeds out all the electronic components C therein, FIG. 10 may be replaced with the detection of the leading electronic component C by the component detection sensor 63, and a determination may be made based on whether or not a certain time has elapsed from the start of driving of the feeding motor 53 in the forward direction.
That is, the elapsed time from the start of driving of the feeding motor 53 in step S3 is measured, and the feeding motor 53 continues to drive forward for a certain time without bending of the insertion member 40 through steps S5 and S7. In this case, it is assumed that all the electronic components C are sent from the component container 20 to the guide portion 61 side, and the driving of the feeding motor 53 is stopped. The fixed time in this case is desirably a time during which all the electronic components C in the component container 20 can be sent out.
In the case of this configuration, it is possible to appropriately stop the advancement of the insertion member 40 without providing the component detection sensor 63 at the component delivery position P.
Moreover, in the said embodiment, in order to respond | correspond to the electronic component with a lead, the cross section along the up-down direction of the component container 20 was a cylinder shape and the portal type | mold, However, As for an electronic component, the shape where a lead extends outside is used. It is not limited to a thing, The cross-sectional shape of the component container 20 can also be matched with the shape of an electronic component. For example, the shape of the component container 20 can be variously changed such as a cylindrical shape or a box shape.
Moreover, in the said embodiment, although the deflection | deviation detection part serves as an origin sensor, another height sensor can be provided as a deflection | deviation detection part, and it can also be considered easily as two height sensors.
