The case 11 is formed in a flat box shape as an overall shape. The case 11 is configured to be expandable and contractable in the electronic component transfer direction (the Y direction in FIG. 2) in order to accommodate sticks of different lengths. Specifically, the case 11 is composed of a front case portion 11a and a rear case portion 11b which are separate members. The front case portion 11a and the rear case portion 11b are slidably assembled to each other.

The supply chute 12 is arranged on the upper front side of the case 11 (upper right side in FIG. 2). The supply chute 12 is formed in a cylindrical shape and has an inner surface corresponding to the outer shape of the electronic components supplied by the stick feeder 10 . The rear end of the supply chute 12 is connected to the front end of the supply stick 90A so that electronic components can flow therethrough. The supply chute 12 forms part of a guide path that guides the electronic components transferred from the front end of the stick 90 to the electronic component supply position Pt.

The component sensor 13 is provided in the supply chute 12 and detects the presence or absence of an electronic component at a predetermined position within the supply chute 12 . When the electronic component is not detected by the component sensor 13 , the tail end of the row of electronic components to be transferred is positioned forward of the component sensor 13 . Accordingly, the feeder control section 80, which will be described later, determines whether or not the supply stick 90A is empty based on the detection result of the component sensor 13. FIG.

The guide device 20 is arranged behind the supply chute 12 in the upper part of the case 11 . The guide device 20 guides the vertical movement of the stacked sticks 90 . The guide device 20 has a pair of stick guides 21, 22 and a pair of pins 23, 24 (see FIGS. 5-7). The front stick guide 21 is fixed to the front case portion 11 a of the case 11 . The rear stick guide 22 is fixed to the rear case portion 11 b of the case 11 . As a result, the pair of stick guides 21 and 22 are configured so that the distance between them can be adjusted according to the length of the stick 90 . A pair of stick guides 21 and 22 support the ends of the stick 90 and regulate the movement of the stick 90 in the longitudinal direction and width direction (X direction in FIG. 2).

As shown in FIGS. 5 to 7, the pair of pins 23 and 24 are arranged in the pair of stick guides 21 and 22, and are provided so as to be able to move forward and backward of the stick feeder 10 by an actuator (not shown). The pair of pins 23 and 24 are arranged at vertical positions corresponding to the spare stick 90B positioned one step above the supply stick 90A among the plurality of sticks 90 . A pair of pins 23 and 24 are driven into openings at both ends of the spare stick 90B by the actuator to prevent the spare stick 90B from falling. Also, the pair of pins 23 and 24 are retracted from the openings at both ends of the spare stick 90B by the actuator, allowing the spare stick 90B to fall.

The stick support device 30 has a front support member 31 and a rear support member 32 that support both ends of the lowest supply stick 90 (supply stick 90A) among the plurality of sticks 90 . The front support member 31 is arranged below the front stick guide 21 and fixed to the case 11 . The rear support member 32 is arranged below the rear stick guide 22 .

The stick support device 30 also has a driving device 40 that moves the rear support member 32 in the longitudinal direction of the stick 90 . The rear support member 32 is connected to a piston rod 45 of the drive device 40 and configured to be movable by the drive device 40 . Thereby, the space|interval of the front side support member 31 and the rear side support member 32 is adjustable. The details of the rear support member 32 of the stick support device 30 and the drive device 40 will be described later.

The extrusion device 50 inserts an extrusion member (not shown) from the rear end side of the supply stick 90A to push out the electronic component from the front end of the supply stick 90A. In addition, when the supply stick 90A is empty, the extrusion device 50 advances the extrusion member further and inserts it into the supply chute 12 . Thereby, the pushing device 50 is configured to be able to transfer the electronic components in the supply chute 12 to the supply position Pt.

The component holding device 60 holds the electronic component transported to the supply position Pt so as to be able to be supplied. Specifically, the component holding device 60 holds electronic components corresponding to the types of the electronic components. As a result, the stick feeder 10 can feed various electronic components so that the component transfer device of the component mounter 1 can hold electronic components having different external shapes. The component holding device 60 forms part of a guide path that guides the electronic components transferred from the front end of the stick 90 to the electronic component supply position Pt.

The feeder control section 80 controls various operations in the stick feeder 10 . The memory of the feeder control unit 80 stores firmware to be executed in controlling the supply of electronic components and set values such as correction amounts. The feeder control unit 80 controls the transfer operation of the pushing device 50 and the component holding device 60 according to command values input from the outside while being held in the slot 2a of the component feeding device 2 so as to be communicable. Also, the feeder control unit 80 determines whether or not the supply stick 90A is empty based on the detection result of the component sensor 13 . The feeder control section 80 controls the operation of exchanging the sticks 90 by the stick support device 30 .

(Detailed configuration of rear support member 32 and driving device 40)
Here, in the stick feeder 10, the case 11 is composed of separate members (the front case portion 11a and the rear case portion 11b) as described above, and can accommodate sticks 90 of different lengths. However, even sticks 90 of the same type have variations in length. Therefore, even if the length of the case 11 is set for each type of stick 90, if the length of the stick 90 is different, a gap is generated between the rear end of the supply shooter 12 and the front end of the supply stick 90A. may affect the transport of

Correspondingly, the stick support device 30 has a rear support member 32 movable with respect to the fixed front support member 31 and a drive device 40 for driving the rear support member 32 . As a result, in this embodiment, the stick support device 30 has the function of exchanging the supply sticks 90, and also pushes the supply sticks 90 forward to create gaps based on variations in the length of the sticks 90. It is configured to have a function of suppressing

Specifically, the driving device 40 moves the rear side support member 32 to three positions: the reference position Ps, the pressing position Pp, and the ejection position Px. The reference position Ps is a position where the stick 90 (preliminary stick 90B) that falls while being guided by the guide device 20 is received as the supply stick 90 (supply stick 90A) (see FIG. 5).

The pressing position Pp is a position where the supply stick 90 (supply stick 90A) is advanced from the reference position Ps and pressed toward the front side support member 31 (see FIG. 6). The ejection position Px is a position where the supply stick 90 (the supply stick 90A) is retracted from the reference position Ps and ejected from between the front side support member 31 (see FIG. 7).

In this embodiment, the rear support member 32 has a support surface 32a and a pressing surface 32b, as shown in FIG. The support surface 32a is formed horizontally and supports the lower surface of the rear end of the supply stick 90A at the reference position Ps. A pressing surface 32b of the rear support member 32 is formed so as to be orthogonal to the support surface 32a. The pressing surface 32b presses the rear end of the supply stick 90A at the pressing position Pp.

5, the front support member 31 has a support surface 31a arranged at the same vertical position as the support surface 32a of the rear support member 32. As shown in FIG. With such a configuration, the front support member 31 and the rear support member 32 support both ends of the supply stick 90A so that the supply stick 90A is horizontal at the reference position Ps and the pressing position Pp.

3 and 4, the driving device 40 includes a first solenoid valve 41, a second solenoid valve 42, an air pump 43, an air cylinder 44, a piston rod 45, a reverse spring 46, and a forward spring. 47. The first solenoid valve 41 and the second solenoid valve 42 are used to control the flow of compressed air supplied from the air pump 43 .

In this embodiment, the first solenoid valve 41 and the second solenoid valve 42 are configured to be independently operable, and when the respective solenoids 41a and 42a are energized, the compressed air is circulated to the air cylinder 44. It is a normally closed type that supplies compressed air. The air pump 43 supplies compressed air to the first solenoid valve 41 and the second solenoid valve 42 . The operation of the air pump 43 is controlled by the feeder control section 80 .

The air cylinder 44 is partitioned into a first air chamber 44 a and a second air chamber 44 b by a head portion 45 a formed on the piston rod 45 . Compressed air is supplied to the first air chamber 44 a via the first solenoid valve 41 . Compressed air is supplied to the second air chamber 44 b via the second solenoid valve 42 . The piston rod 45 is movably supported in the axial direction of the air cylinder 44 . A rear support member 32 is fixed to the end of the piston rod 45 .

The retraction spring 46 and the forward spring 47 are arranged on the outer peripheral side of the piston rod 45 . A retraction spring 46 and an advancement spring 47 axially urge the piston rod 45 to return the head portion 45a of the piston rod 45 to the neutral position. That is, according to the driving device 40 configured as described above, the piston rod 45 is returned to the neutral position when both the two solenoids 41a and 42a are not energized. As a result, the rear support member 32 connected to the piston rod 45 is positioned at the reference position Ps.

Further, for example, when the solenoid 41a of the first solenoid valve 41 is excited by power supply, the first solenoid valve 41 is opened. Compressed air is thereby supplied from the air pump 43 to the first air chamber 44 a via the first solenoid valve 41 . As a result, the piston rod 45 moves while compressing the retraction spring 46 . As a result, the rear side support member 32 connected to the piston rod 45 is moved from the reference position Ps to the pressing position Pp.

Further, for example, when the solenoid 42a of the second solenoid valve 42 is excited by power supply, the second solenoid valve 42 is opened. Compressed air is thereby supplied from the air pump 43 to the second air chamber 44b via the second solenoid valve 42 . As a result, the piston rod 45 moves while compressing the forward spring 47 . As a result, the rear support member 32 connected to the piston rod 45 is moved to the ejection position Px, which is retracted from the reference position Ps.

When power supply to the two solenoids 41a and 42a is cut off and both are not energized, air is discharged from the first air chamber 44a and the second air chamber 44b by the elastic forces of the backward spring 46 and the forward spring 47. be. Thereby, the piston rod 45 is returned to the neutral position. In this way, the driving device 40 includes the first solenoid valve 41 that switches the three positions (the reference position Ps, the pressing position Pp, and the discharge position Px) of the rear support member 32 according to the state of power supply to the two solenoids 41a and 42a. and a second solenoid valve 42 .

In this embodiment, the driving device 40 is a combination of two two-position valves (the first solenoid valve 41 and the second solenoid valve 42) that operate independently to constitute a solenoid valve that switches between three positions as a whole. I assumed. Alternatively, a three-position valve that switches between three positions using two solenoids may be applied.

(Replacement operation of stick 90)
The stick feeder 10 configured as described above performs a replacement operation of the stick 90, for example, when the supply stick 90A becomes empty. First, based on the detection result of the parts sensor 13, the feeder control unit 80 recognizes that the tail end of the electronic parts is closer to the supply position Pt than the position where the parts sensor 13 is arranged, and feeds the supply stick 90A. is empty.

The drive device 40 of the stick support device 30 cuts off power supply to the solenoid 41a of the first solenoid valve 41 to bring it into a non-excited state. As a result, the supply of compressed air to the air cylinder 44 is cut off, and the piston rod 45 moves to the neutral position. The rear support member 32 retreats from the pressing position Pp to the reference position Ps as the piston rod 45 moves.

Also, the feeder control unit 80 recognizes that one or more spare sticks 90B are being guided by the guide device 20 based on the detection result of a sensor (not shown). The guide device 20 allows the pair of pins 23 and 24 to enter openings at both ends of the spare stick 90B to regulate the vertical movement of the spare stick 90B. As a result, the one or more spare sticks 90B are prevented from falling.

Next, the stick support device 30 supplies power to the solenoid 42a of the second solenoid valve 42 to energize it. As a result, compressed air is supplied to the air cylinder 44 via the second solenoid valve 42, and as shown in FIG. 7, the rear support member 32 retreats from the reference position Ps to the discharge position Px. Then, the distance between the front side support member 31 and the rear side support member 32 becomes wider than the length of the empty stick 90C, and the empty stick 90C is ejected.

Subsequently, the stick support device 30 shuts off power supply to the solenoid 42a of the second solenoid valve 42 to bring it into a non-excited state. As a result, the supply of compressed air to the air cylinder 44 is cut off, and the piston rod 45 moves to the neutral position. The rear support member 32 advances from the discharge position Px to the reference position Ps as the piston rod 45 moves.

In this state, when the guide device 20 retracts the pair of pins 23 and 24 from the openings at both ends of the spare stick 90B, the spare stick 90B falls. As shown in FIG. 5, the spare stick 90B that has fallen is handled by the front support member 31 and the rear support member 32 at the reference position Ps as the next supply stick 90 (new supply stick 90A). Acceptable. At this time, the distance between the rear end of the supply chute 12 and the pressing surface 32b of the rear support member 32 is longer than the supply stick 90A.

The stick support device 30 supplies power to the solenoid 41a of the first solenoid valve 41 to energize it. As a result, compressed air is supplied to the air cylinder 44 via the first solenoid valve 41, and as shown in FIG. 6, the rear support member 32 advances from the reference position Ps to the pressing position Pp. Then, the rear end of the supply stick 90A comes into contact with the pressing surface 32b and is pressed toward the front support member 31 side.

As a result, the supply stick 90A is moved to a position where the front end contacts the rear end of the supply shooter 12, and is sandwiched between the rear end surface of the supply shooter 12 and the pressing surface 32b of the rear support member 32. Become. Thereby, the supply stick 90A is connected to the supply shooter 12 so that the electronic components can be circulated regardless of variations in length.

By repeating the above operations, the stick 90 is appropriately exchanged. In addition, in the operating state in which the stick feeder 10 supplies electronic components, control is performed so that the supply stick 90A is always pressed against the supply chute 12 . Further, when the position of the supply stick 90A pressed toward the supply chute 12 side is held by, for example, a frictional force with the front side support member 31, the rear side support member 32 is moved to the reference position in the operating state. It may be controlled to return to Ps.

(Effects of Configuration of Embodiment)
The stick feeder 10 feeds the electronic components by pushing out the electronic components from the front end of a stick 90 containing a plurality of electronic components. The stick feeder 10 includes a guide device 20 that guides the vertical movement of a plurality of stacked sticks 90, a front support member 31 that supports both ends of the lowest feeding stick 90 among the plurality of sticks 90, and A rear support member 32 and a driving device 40 for moving the rear support member 32 in the longitudinal direction of the stick 90 are provided.
The drive device 40 moves the stick 90 for supply forward from the reference position Ps to the front side support member 31 side by moving the stick 90 for supply to the front side support member 31 side. The rear support member 32 is moved to three positions: a pressing position Pp for pressing, and an ejection position Px for ejecting the supply stick 90 from the front support member 31 by retracting from the reference position Ps.

With such a configuration, the stick feeder 10 presses the feed stick 90 toward the front support member 31 by the rear support member 32 . As a result, the front end of the feed stick 90 is pressed against a member (the feed shooter 12 in this embodiment) on the front side of the stick feeder 10 . Therefore, regardless of the length of the stick 90 for supply, the occurrence of a gap between the supply chute 12 and the guide path is suppressed. Therefore, the stick feeder 10 allows the lengths of the plurality of sticks 90 to be different, so that the electronic components can be preferably moved.

The driving device 40 also has solenoid valves (a first solenoid valve 41 and a second solenoid valve 42) that switch between three positions of the rear support member 32 according to the state of power supply to the two solenoids 41a and 42a.
With this configuration, the position of the rear support member 32 is switched by the two solenoids 41a and 42a, so that the rear support member 32 can be reliably operated while reducing manufacturing costs. Also, by using two solenoids 41a and 42a, it is possible to reliably control the operation of switching between the three positions (reference position Ps, pressing position Pp, ejection position Px) of the rear support member 32 .

Further, the driving device 40 sets the rear support member 32 to the reference position Ps in a state in which both the two solenoids 41a and 42a are not energized.
With such a configuration, power is not supplied to the two solenoids 41a, 42a when receiving the falling spare stick 90 for supply. As a result, malfunction of the rear support member 32 can be prevented, and the falling backup stick 90 can be reliably received for supply.

The rear support member 32 has a support surface 32a that supports the lower surface of the rear end of the supply stick 90 at the reference position Ps, and a rear end of the supply stick 90 that is perpendicular to the support surface 32a and at the pressing position Pp. and a pressing surface 32b for pressing the .
With such a configuration, the stick feeder 10 maintains the stick 90 in a predetermined posture (horizontal posture in this embodiment) by the support surface 32a, and pushes the stick 90 toward the front support member 31 by the pressing surface 32b. can be reliably pressed. Therefore, the operation of the stick feeder 10 can be stabilized. In addition, compared to a configuration in which the support surface 32a is inclined, the posture of the stick 90 can be maintained constant regardless of the length and longitudinal position of the stick 90. FIG.

Also, the front support member 31 and the rear support member 32 support both ends of the supply stick 90 so that it is horizontal at the reference position Ps and the pressing position Pp.
Here, in the drop-type stick feeder 10 that supports the stick 90 in a substantially horizontal posture, the difference in the length of the stick 90 particularly affects the occurrence of a gap between the stick 90 and the feed chute. On the other hand, as in the configuration of the present embodiment, by adopting a configuration in which the stick 90 is supported in a horizontal posture, the gap and angle at the connecting portion between the supply shooter 12 and the stick 90 are eliminated, and the electronic It becomes possible to transfer the parts favorably.

<Modification of Embodiment>
(Regarding drive device 40)
In the embodiment, the drive device 40 is configured such that the piston rod 45 is returned to the neutral position and the rear side support member 32 is set to the reference position Ps when the two solenoids 41a and 42a are not energized. On the other hand, the driving device 40 may be configured such that the rear side support member 32 is set at the pressing position Pp or the ejecting position Px in a state in which both the two solenoids 41a and 42 are not energized.

For example, when the drive device 40 is configured to set the rear support member 32 to the pressing position Pp in the above state, the elastic force of the forward spring 47 presses the supply stick 90A forward. As a result, when the stick feeder 10 is in operation, the supply stick 90A can be kept pressed against the end of the supply chute 12 without supplying power to the two solenoids 41a and 42a.

In the embodiment, the driving device 40 is configured to switch between three positions (reference position Ps, pressing position Pp, ejection position Px) of the rear support member 32 by operating the first solenoid valve 41 and the second solenoid valve 42. and On the other hand, the driving device 40 can employ actuators other than solenoid valves. For example, the drive device 40 may be configured to steplessly position the rear support member 32 at positions in the front-rear direction including the above three positions by the operation of the electric motor.

(Regarding the rear support member 32)
In the embodiment, the rear support member 32 is configured to have a planar support surface 32a and a pressing surface 32b. On the other hand, the rear support member 32 can be appropriately set in a shape corresponding to the function of exchanging the sticks 90 and the function of pressing the sticks 90 provided in the stick support device 30 . For example, when the rear support member 32 receives the spare stick 90B dropped at the reference position Ps for supply, the rear support member 32 has a slope on the upper part of the pressing surface 32b that guides the spare stick 90B so as to correct the deviation in the length direction. It is good also as a structure formed.

Further, the pressing surface 32b of the rear support member 32 may be set to a shape corresponding to the shape of the opening at the end of the supply stick 90A instead of being planar. Also, the pressing surface 32b may be formed of a material that prevents slipping on the end of the feeding stick 90A, or a cushioning material that has a certain degree of elasticity. With such a configuration, it is possible to improve the stability of the operation when the rear support member 32 presses the supply stick 90A.
