The

return guide portions

23 and 33 guide the component C conveyed by the 2 nd conveyor belt 22 to the drop position IP. The

return guide portions

23 and 33 guide the component C so that the component C conveyed to the return position TP by the 2 nd conveyor belt 22 is thrown to the throw-in position IP located on the left side of the return position TP. The return guide 33 is disposed rearward of the return guide 23.

The front end of the return guide 33 is disposed above the 1 st conveyor belt 21. The return guide 33 is in contact with the conveying surface 220 of the 2 nd conveying belt 22. The return guide 33 is separated from the conveying surface 210 of the 1 st conveying belt 21. The return position TP includes a position where the conveying surface 220 of the 2 nd conveying belt 22 faces the return guide 33.

In the embodiment, the height of the conveying surface 220 of the 2 nd conveyor belt 22 at the return position TP is higher than the height of the conveying surface 210 of the 1 st conveyor belt 21 at the input position IP. The component C conveyed from the retracted position JP to the returning position TP is guided leftward by the returning

guide portions

The components C stacked in the vertical direction are dropped to the input position IP of the 1 st transport belt 21 by the

return guide portions

23 and 33 at different timings. Thus, even if a large amount of the component C is conveyed to the return position TP, the component C is prevented from staying at the return position TP. Therefore, the component C is smoothly conveyed.

Further, for example, a blower may function as the

return guide

23, 33.

The rotation shaft of the motor 24, the rotation shaft of the 1 st gear 25, the rotation shaft of the 2 nd gear 26, the rotation shaft of the drive pulley 27, the rotation shaft of the 2-stage driven pulley 28, and the rotation shafts of the

idle pulleys

29, 30, 31, and 32 extend in the left-right direction, respectively.

Fig. 11 is a perspective view of the motor 24 according to the embodiment. As shown in fig. 6, 7, 8, 9, 10, and 11, the motor 24 is supported by the support plate 18. The motor 24 generates a rotational force for driving each of the 1 st conveyor belt 21 and the 2 nd conveyor belt 22. The motor 24 is a stepping motor.

The 1 st gear 25 is coupled to a rotor shaft of the motor 24. The rotor shaft of the motor 24 rotates, whereby the 1 st gear 25 rotates. The motor 24 can rotate the 1 st gear 25 forward and backward.

The 2 nd gear 26 is disposed rearward of the 1 st gear 25. The 2 nd gear 26 meshes with the 1 st gear 25. The 1 st gear 25 rotates, whereby the 2 nd gear 26 rotates. The rotation direction of the 1 st gear 25 and the rotation direction of the 2 nd gear 26 are different. For example, when the 1 st gear 25 rotates forward, the 2 nd gear 26 rotates backward. When the 1 st gear 25 is rotated in the reverse direction, the 2 nd gear 26 is rotated in the normal direction.

The drive pulley 27 is disposed on the left of the 2 nd gear 26. The drive pulley 27 is coupled to the 2 nd gear 26. The rotation axis of the drive pulley 27 coincides with the rotation axis of the 2 nd gear 26. The 2 nd gear 26 rotates, whereby the drive pulley 27 rotates together with the 2 nd gear 26. That is, the rotation direction of the drive pulley 27 is the same as the rotation direction of the 2 nd gear 26. For example, when the 2 nd gear 26 rotates in the normal direction, the drive pulley 27 also rotates in the normal direction. In the case where the 2 nd gear 26 is reversed, the drive pulley 27 is also reversed.

The 1 st conveyor belt 21 is supported by a drive pulley 27. The inner surface of the 1 st conveyor belt 21 is in contact with the surface of the drive pulley 27. The drive pulley 27 rotates, whereby the 1 st conveyor belt 21 is driven.

The 2-stage driven pulley 28 is disposed rearward of the 2 nd gear 26 and the drive pulley 27. The 2-stage driven pulley 28 has a large diameter portion 281 and a small diameter portion 282. The diameter of the large diameter portion 281 is larger than that of the small diameter portion 282. The large diameter portion 281 is disposed on the left of the small diameter portion 282. The large diameter portion 281 and the small diameter portion 282 are integral. The rotation axis of the large diameter portion 281 and the rotation axis of the small diameter portion 282 coincide with each other. The large diameter portion 281 rotates, and thereby the small diameter portion 282 rotates together with the large diameter portion 281. That is, the rotation direction of the large diameter portion 281 is the same as the rotation direction of the small diameter portion 282. For example, when large diameter portion 281 rotates normally, small diameter portion 282 also rotates normally. When the large diameter portion 281 is reversed, the small diameter portion 282 is also reversed.

The 1 st conveyor 21 is supported by the large diameter portion 281. The outer surface of the 1 st conveyor belt 21 is in contact with the surface of the large diameter portion 281. The drive pulley 27 rotates, and the 1 st conveyor belt 21 is driven, whereby the large diameter portion 281 rotates.

The 2 nd conveyor belt 22 is supported by the small diameter portion 282. The inner surface of the 2 nd belt 22 contacts the surface of the small diameter portion 282. The large diameter portion 281 rotates and the small diameter portion 282 rotates, whereby the 2 nd transport belt 22 is driven.

The surface of the large diameter portion 281 contacts with the outer surface of the 1 st conveyor belt 21. The surface of the small diameter portion 282 contacts the inner surface of the 2 nd conveying belt 22. Therefore, the 1 st transport belt 21 is driven to move the transport surface 210 forward, and when the large diameter portion 281 rotates, the small diameter portion 282 rotates together with the large diameter portion 281, and the 2 nd transport belt 22 is driven to move the transport surface 220 backward.

As described above, in the embodiment, both the 1 st conveyor belt 21 and the 2 nd conveyor belt 22 are driven by the rotational force generated by the 1 motor 24. The 1 st conveyor belt 21 and the 2 nd conveyor belt 22 are each supported by a2 nd-stage driven pulley 28. The 2 nd conveyor belt 22 is driven in synchronization with the 1 st conveyor belt 21. Further, both the 1 st conveyor belt 21 and the 2 nd conveyor belt 22 are driven by the rotational force generated by the 1 st motor 24 so that the conveying direction of the 1 st conveyor belt 21 is opposite to the conveying direction of the 2 nd conveyor belt 22.

The conveying speed of the 1 st conveyor belt 21 is higher than that of the 2 nd conveyor belt 22. The 1 st conveyor 21 is supported by the large diameter portion 281. The 2 nd conveyor belt 22 is supported by the small diameter portion 282. Therefore, the large diameter portion 281 and the small diameter portion 282 of the 2-stage driven pulley 28 rotate together, and thus the conveying speed of the 1 st conveyor belt 21 is higher than the conveying speed of the 2 nd conveyor belt 22.

The conveying speed of the 1 st conveyor belt 21 is higher than the conveying speed of the 2 nd conveyor belt 22, so the component C can be smoothly transferred from the 2 nd conveyor belt 22 to the 1 st conveyor belt 21. Further, since the components C are fed from the 2 nd conveyor belt 22 to the 1 st conveyor belt 21 and then conveyed at a high speed, the components C are prevented from staying on the 1 st conveyor belt 21. Therefore, the component C is smoothly conveyed.

In the embodiment, the 2 nd gear 26 and the drive pulley 27 are rotatably supported by the carrier 35. The bracket 35 is supported by the support plate portion 18. The 2-stage driven pulley 28 is rotatably supported by the carrier 36. The bracket 36 is supported by the support plate portion 18.

The idler pulley 29 is provided in plurality. The 1 st conveyor belt 21 is movably supported by a plurality of idler pulleys 29. The idler pulley 30 is provided in plurality. The plurality of idler pulleys 30 are in contact with the 1 st conveyor belt 21, and adjust the tension of the 1 st conveyor belt 21.

The idle pulley 31 is provided in plurality. The 2 nd transport belt 22 is movably supported by a plurality of idler pulleys 31. The idler pulley 32 is provided in plurality. The plurality of idler pulleys 32 are in contact with the 2 nd transport belt 22, and adjust the tension of the 2 nd transport belt 22.

The simple component sorting unit 34 is disposed between the input position IP and the supply position SP. The simple component sorting unit 34 is supported by at least a part of the housing 11. In the embodiment, the base end portion of the simple component sorting section 34 is supported by the left plate section 12. The sorting surface of the simple component sorting section 34 is inclined forward and rightward. The simple component sorting unit 34 is disposed above the 1 st conveyor belt 21. In the embodiment, the simple component sorting unit 34 is disposed to face a part of the conveyance surface 210 in the inclined surface portion 211. The simple component sorting unit 34 is separated from the conveying surface 210 of the 1 st conveyor belt 21.

The plurality of components C loaded at the loading position IP may be conveyed to the supply position SP by the 1 st conveyor 21 in a vertically overlapped state. The simple component sorting unit 34 restricts conveyance of an upper component C among the components C stacked in the vertical direction. Among the components C stacked in the vertical direction, the lower component C passes below the simple component sorting unit 34. That is, some of the components C stacked in the vertical direction abut on the sorting surface of the simple component sorting unit 34, and the conveyance to the supply position SP is suppressed. Some of the components C stacked in the vertical direction pass between the simple component sorting unit 34 and the 1 st conveyor belt 21. Thereby, the number of components C supplied from the drop position IP to the supply position SP is adjusted. Further, the component C is prevented from falling to the outside of the component supply apparatus 100.

Further, for example, a blower may function as the simple component sorting section 34.

In the embodiment, the base end portion of the partition portion 61 is supported by the left plate portion 12. The partition plate surface of the partition plate portion 61 is inclined rightward and forward.

The 1 st sorting unit 60 passes only the components C in the 1 st posture one by one. In the embodiment, the 1 st posture of the component C is a posture in which the vertical dimension of the component C is smallest. The 1 st posture of the component C is a posture in which the conveying surface 420 of the 1 st conveying member 42A and the 2 nd side surface Dd of the body D are in contact. The partitioning portion 61 is separated by a predetermined amount upward from the conveying surface 420 of the 1 st conveying member 42A so that only the member C in the 1 st posture passes through.

Fig. 15 is a schematic diagram for explaining the 1 st sorting unit 60 according to the embodiment. As shown in fig. 15(a), in the 1 st posture in which the conveyance surface 420 of the 1 st conveyance member 42A and the 2 nd side surface Dd of the main body D are in contact, the member C can pass below the partitioning portion 61.

As shown in fig. 15(B), in a state where the conveyance surface 420 of the 1 st conveyance member 42A and the 1 st side surface Dc of the main body D are in contact, the main body D is stopped by the partition portion 61, and the member C cannot pass below the partition portion 61.

As shown in fig. 15(C), in a state where the conveyance surface 420 of the 1 st conveyance member 42A is in contact with the upper surface Da of the main body D, the lead E is blocked by the separator 61, and the member C cannot pass below the separator 61.

As shown in fig. 15(D), when the component C is conveyed in the state of being overlapped while being in the 1 st posture, the upper component C is stopped by the partition portion 61, and the upper component C cannot pass below the partition portion 61.

< 2 nd sorting section >

The 2 nd sorting unit 70 is disposed between the 1 st sorting unit 60 and the pickup position PP. The 2 nd sorting unit 70 is vibrated by the vibrator 41. The 2 nd sorting unit 70 has a guide portion 71 disposed on the left side of the conveying surface 420 of the 3 rd conveying member 42C. The 3 rd conveying member 42C has a conveying surface 420 and an inclined surface 72. The inclined surface 72 of the 3 rd conveying member 42C is disposed on the right side of the conveying surface 420 of the 3 rd conveying member 42C. The inclined surface 72 is disposed below the conveying surface 420 of the 3 rd conveying member 42C. The inclined surface 72 is inclined rightward and downward.

The component C having passed through the 1 st sorting unit 60 is conveyed to the 2 nd conveying component 42B, and then conveyed to the 3 rd conveying component 42C of the 2 nd sorting unit 70. The component C having passed through the 2 nd conveyance component 42B is supplied to the 3 rd conveyance component 42C.

The guide portion 71 guides the member C supplied from the 2 nd conveying member 42B and conveyed to the 3 rd conveying member 42C forward. The guide portion 71 is disposed on the left side of the conveying surface 420 of the 3 rd conveying member 42C.

In the left-right direction, the size of the conveying surface 420 of the 3 rd conveying member 42C is smaller than the size of the conveying surface 420 of the 1 st conveying member 42A and the size of the conveying surface 420 of the 2 nd conveying member 42B.

The 2 nd sorting unit 70 passes only the component C in the 1 st posture and the 2 nd posture. In the embodiment, the 2 nd posture of the component C is a posture in which the lead E protrudes from the body D in a specified direction. In the embodiment, the 2 nd posture of the component C is a posture in which the lead E protrudes rightward from the body D. The left-right direction dimension of the conveying surface 420 of the 3 rd conveying member 42C is determined to be passed by only the member C in the 2 nd posture.

Fig. 16 is a schematic diagram for explaining the 2 nd sorting unit 70 according to the embodiment. As shown in fig. 16(a), in the 2 nd posture in which the upper surface Da of the main body D faces the guide portion 71 and the lead E protrudes rightward from the main body D, the component C can pass through the 3 rd conveying member 42C.

As shown in fig. 16(B), in a state where the lead E protrudes forward or backward from the main body D, the component C cannot pass through the 3 rd feeding member 42C. That is, in a state where the lead E protrudes forward or backward from the main body D, the dimension in the left-right direction of the conveying surface 420 of the 3 rd conveying member 42C is sufficiently smaller than the dimension in the left-right direction of the main body D, and therefore the contact area between the main body D and the conveying surface 420 in the state shown in fig. 16(B) is smaller than the contact area between the main body D and the conveying surface 420 when the member C is in the 2 nd posture. When the contact area between the main body D and the conveying surface 420 is small, the component C falls to the right from the conveying surface 420 of the 3 rd conveying member 42C due to the gravity.

As shown in fig. 16(C), even in a state where the lead E protrudes leftward from the body D, the component C cannot pass through the 3 rd feeding component 42C. That is, in a state where the lead E protrudes leftward from the body D, the contact area between the body D and the conveying surface 420 is smaller than the contact area between the body D and the conveying surface 420 when the component C is in the 2 nd posture. When the contact area between the main body D and the conveying surface 420 is small, the component C falls to the right from the conveying surface 420 of the 3 rd conveying member 42C due to the gravity.

As described above, the 2 nd sorting unit 70 passes only the component C in the 2 nd posture. The component C that cannot pass through the 3 rd conveying component 42C falls from the 2 nd sorting portion 70. That is, the 2 nd sorting unit 70 drops the component C not in the 2 nd posture from the 2 nd sorting unit 70.

In the embodiment, the 2 nd sorting part 70 drops the component C not in the 2 nd posture from the 2 nd sorting part 70 to the retreat position JP of the 2 nd conveying belt 22. In the front-rear direction, the position of the 2 nd sorting portion 70 and the position of at least a part of the 2 nd conveying belt 22 are equal. The 2 nd sorting section 70 drops the component C not in the 2 nd posture to the retreat position JP of the 2 nd conveying belt 22. In the embodiment, the member C falling to the right from the conveying surface 420 of the 3 rd conveying member 42C falls to the retreat position JP of the 2 nd conveying belt 22 via the inclined surface 72.

The dimension of the conveying surface 420 of the 3 rd conveying member 42C in the left-right direction can be adjusted. The dimension in the left-right direction of the conveying surface 420 of the 3 rd conveying member 42C can be adjusted by, for example, adjusting the position of the guide portion 71 in the left-right direction. The dimension of the conveying surface 420 of the 3 rd conveying member 42C in the left-right direction is adjusted based on the outer shape and the dimension of the member C so that only the member C in the 2 nd posture passes through.

< Direction setting part >

The direction setting part 80 is disposed between the 2 nd sorting part 70 and the pickup position PP. The direction setting unit 80 adjusts the component C that has passed through the 2 nd position of the 2 nd sorting unit 70 to the 3 rd position.

The direction setting section 80 includes: a guide part 81 disposed on the right side of the conveyance surface 420 of the 4 th conveyance member 42D; a guide portion 82 disposed on the left side of the conveying surface 420 of the 4 th conveying member 42D; a guide portion 83 disposed in front of the guide portion 81; a guide portion 84 disposed in front of the guide portion 83; a guide section 85 disposed in front of the guide section 82; and a posture adjustment portion 86 supported by the guide portion 85. The 4 th conveying member 42D, the guide portion 81, the guide portion 82, the guide portion 83, the guide portion 84, the guide portion 85, and the posture adjustment portion 86 are each vibrated by the driving of the vibrator 41.

The guide 81 and the guide 82 each guide the component C passing through the 2 nd sorting unit 70 forward. The guide portion 81 and the guide portion 82 are opposed. The guide portion 81 and the guide portion 82 are parallel.

The guide portion 83, the guide portion 84, and the guide portion 85 each guide the member C passing between the guide portion 81 and the guide portion 82 forward. The guide portion 85 faces the guide portion 83 and the guide portion 84, respectively. The guide portion 83 is inclined so as to approach the guide portion 85 toward the front. The guide portion 84 and the guide portion 85 are parallel. In the front-rear direction, the position of the front end portion of the guide portion 81 and the position of the rear end portion of the guide portion 83 are substantially equal. In the front-rear direction, the position of the front end of the guide portion 83 is substantially equal to the position of the rear end of the guide portion 84. The distance between the guide portion 84 and the guide portion 85 is shorter than the distance between the guide portion 81 and the guide portion 82.

The posture adjusting part 86 adjusts the component C in the 2 nd posture to the 3 rd posture. The 3 rd posture is a posture in which the lead E protrudes downward from the body D. The posture adjustment portion 86 is fixed to the guide portion 85. The posture adjustment portion 86 is inclined upward toward the front.

Fig. 17 is a schematic diagram for explaining the direction setting unit 80 according to the embodiment. The component C from the 2 nd sorting part 70 passes between the guide part 81 and the guide part 82 in a state of maintaining the 2 nd posture. The body D of the member C passing between the guide part 81 and the guide part 82 is in contact with the attitude adjusting part 86. If the body D moves forward while being in contact with the attitude adjustment portion 86, the body D gradually rises. Further, in a state where the main body D moves forward while being in contact with the posture adjustment portion 86, the leading end portion of the lead wire E is guided by the guide portion 83. The component C moves forward while the body D is guided by the posture adjustment portion 86 and the lead E is guided by the guide portion 83, whereby the posture of the component C changes from the 2 nd posture to the 3 rd posture. The component C adjusted to the 3 rd posture moves between the guide part 84 and the guide part 85 to reach the pickup position PP while maintaining the 3 rd posture. Thereby, as shown in fig. 17, the component C in the 3 rd posture is disposed at the pickup position PP. The mounting head 5 is at the pickup position PP, and can hold the upper surface Da of the main body D by the suction nozzle 4.

< control System >

Fig. 20 is a functional block diagram showing a control system 101 of the feeder 10 according to the embodiment. As shown in fig. 20, the control system 101 has a control device 110, a motor 24, a vibrator 41, a rotation sensor 120, a component sensor 130, an operation device 140, and a notification device 150.

The control device 110 includes a computer system. The control device 110 has a processor 111, a main memory 112, a storage 113, and an interface 114. The processor 111 is exemplified by a CPU (Central Processing Unit) or an MPU (micro Processing Unit). As the main memory 112, a nonvolatile memory or a volatile memory is exemplified. As the nonvolatile memory, a rom (read Only memory) is exemplified. As the volatile memory, a ram (random Access memory) is exemplified. As the storage 113, a Hard Disk Drive (HDD) or a Solid State Drive (SSD) is exemplified. As the interface 114, an input-output circuit or a communication circuit is exemplified.

The interface 114 is connected to the motor 24, the vibrator 41, the rotation sensor 120, the member sensor 130, the operation device 140, and the notification device 150, respectively. Interface 114 communicates with motor 24, vibrator 41, rotation sensor 120, member sensor 130, operation device 140, and notification device 150, respectively.

The motor 24 drives the 1 st conveyor belt 21 and the 2 nd conveyor belt 22, respectively.

The vibrator 41 vibrates the conveying member 42.

The rotation sensor 120 detects the state of the motor 24. The state of the motor 24 includes a rotation state of the motor 24. As described above, in the embodiment, the motor 24 includes a stepping motor. The state of the motor 24 includes step motor misalignment. The step-out of the stepping motor is caused by an overload applied to the stepping motor, a rapid change in the rotational speed of the stepping motor, or the like, and means a state in which the pulse signal input to the stepping motor and the rotation of the stepping motor are out of synchronization. For example, in the case where the member C is sandwiched between the 1 st conveyor belt 21 and the housing 11 or between the 1 st conveyor belt 21 and the conveying member 42, an overload is applied to the motor 24 via the 1 st conveyor belt 21, and the possibility of the motor 24 being out of order increases. Similarly, when the component C is sandwiched between the 2 nd conveyor belt 22 and the housing 11, an excessive load is applied to the motor 24 via the 2 nd conveyor belt 22, and the possibility of the motor 24 being out of order increases. In the embodiment, as shown in fig. 7, 8, and 9, the rotation sensor 120 is disposed on the 2-stage driven pulley 28.

Fig. 21 is a left side view showing the rotation sensor 120 according to the embodiment. The rotation sensor 120 is disposed on the 2-stage driven pulley 28. The rotation sensor 120 detects the rotation state of the 2-stage driven pulley 28, thereby detecting the state of the motor 24.

As described with reference to fig. 11 and the like, the 2-stage driven pulley 28 supports the 1 st conveyor belt 21 and the 2 nd conveyor belt 22, respectively. When an overload is applied to the 1 st conveyor belt 21 or the 2 nd conveyor belt 22, the rotation state of the 2-stage driven pulley 28 becomes abnormal. The rotation sensor 120 detects the rotation state of the 2-stage driven pulley 28, and thus can appropriately detect the state of the motor 24.

In the embodiment, the slit plate 121 is fixed to the 2-stage driven pulley 28. As shown in fig. 11, the slit plate 121 is disposed between the large-diameter portion 281 and the small-diameter portion 282. The slit plate 121 is substantially disc-shaped. The slit plate 121 has a diameter larger than the diameter of the large-diameter portion 281 and the diameter of the small-diameter portion 282. If the 2-stage driven pulley 28 rotates, the slit plate 121 rotates together with the 2-stage driven pulley 28. The slit plate 121 has slits 122. The slit plate 121 has 1 slit 122.

The rotation sensor 120 is disposed opposite to at least a portion of the slit plate 121. The rotation sensor 120 is an optical sensor that detects the slit 122. In the case where the motor 24 is normally rotated, the slit 122 is detected by the rotation sensor 120 at a certain cycle. In the case where the motor 24 is out of order, the slit 122 is irregularly and periodically detected by the rotation sensor 120.

The component sensor 130 detects the state of the component C in the conveying component 42. The state of the component C includes the amount (number) of the component C in the conveying member 42 and the presence or absence of the component C in the conveying member 42. In the embodiment, the component sensor 130 includes a component full sensor 131 and a component presence/absence sensor 132 disposed at a position different from the component full sensor 131. In the embodiment, the component full sensor 131 is disposed rearward of the component presence sensor 132.

As shown in fig. 13 and the like, the component full sensor 131 is disposed on the left side of the 4 th conveyance component 42D. The component full sensor 131 detects the amount (number) of the components C in the 4 th conveyance component 42D. The component-full sensor 131 may be an optical sensor that detects the amount of the component C by emitting detection light, or may be a contact sensor that detects the amount of the component C by bringing a probe into contact with the component C. Whether or not the component C is full is detected based on the detection data of the component full sensor 131.

As shown in fig. 13 and the like, the component presence sensor 132 is disposed on the left side of the pickup position PP. The component presence sensor 132 detects the presence or absence of the component C at the pickup position PP. The component presence sensor 132 may be an optical sensor that detects the presence or absence of the component C by emitting detection light, or may be a contact sensor that detects the presence or absence of the component C by bringing a probe into contact with the component C. The presence or absence of the component C at the pickup position PP is detected based on the detection data of the component presence or absence sensor 132. The detection data of the component presence/absence sensor 132 is transmitted to the component mounting apparatus 1. The component mounting apparatus 1 controls the suction timing of the component C relating to the suction nozzle 4 based on the detection data of the component presence/absence sensor 132.

The operation device 140 is operated to drive and stop the motor 24. Further, the operation device 140 is operated to switch the rotation direction of the motor 24. In an embodiment, the operating means 140 comprises a push button. For example, the operating device 140 is pushed long, whereby the motor 24 is driven or stopped. For example, the operating device 140 is continuously pressed 2 times, whereby the rotation direction of the motor 24 is switched. If the operation device 140 is operated, the rotation direction of the motor 24 is switched so that the conveying surface 210 of the 1 st conveyor belt 21 moves backward. As shown in fig. 18 and 19, the operation device 140 is disposed outside the housing 11.

In the embodiment, the operation device 140 functions as the notification device 150. The operating means 140 and the notification means 150 are integral. The notification device 150 operates when the state of the motor 24 is abnormal. The notification device 150 comprises a light. The lamp comprises a Light Emitting Diode (LED). When the state of the motor 24 is abnormal, the lamp blinks.

The control device 110 includes a motor control unit 111A, a vibrator control unit 111B, a motor state determination unit 111C, a member state determination unit 111D, and a notification control unit 111E. The processor 111 functions as a motor control unit 111A, a vibrator control unit 111B, a motor state determination unit 111C, a member state determination unit 111D, and a notification control unit 111E.

The motor control unit 111A outputs a control command for controlling the motor 24. When the conveying surface 210 of the first conveyor belt 21 is moved forward, the motor control unit 111A controls the motor 24 so that the rotor of the motor 24 rotates forward.

When the conveying surface 210 of the 1 st conveyor belt 21 is moved backward, the motor control unit 111A controls the motor 24 so that the rotor of the motor 24 is reversed. When the component C is conveyed from the input position IP to the supply position SP by the 1 st conveyor 21, the motor control unit 111A controls the motor 24 so that the conveying surface 210 of the 1 st conveyor 21 moves forward.

When the operator operates the operation device 140, the motor control unit 111A controls the motor 24 to move the conveying surface 210 of the 1 st conveyor belt 21 rearward based on the operation signal of the operation device 140.

The vibrator control unit 111B outputs a control command for controlling the vibrator 41. When the conveying member 42 is vibrated, the vibrator control section 111B controls the vibrator 41 so that the vibrator 41 vibrates.

The motor state determination unit 111C determines whether or not the state of the motor 24 is abnormal based on the detection data of the rotation sensor 120. The abnormal state of the motor 24 includes a step-out of the motor 24. When the motor state determination unit 111C determines that the state of the motor 24 is abnormal, the motor control unit 111A stops the motor 24.

The component state determination unit 111D determines whether or not the state of the component C is full based on the detection data of the component sensor 130. The case where the component C is full includes a case where the amount (number) of the component C in the conveyance member 42 is more than a predetermined threshold value. When the component state determination unit 111D determines that the state of the component C is full in a state where the motor 24 is rotating and the conveying surface 210 of the 1 st conveyor belt 21 is moving forward, the motor control unit 111A controls the motor 24 to move backward and then stop the conveying surface 210 of the 1 st conveyor belt 21. The vibrator control unit 111B stops the vibrator 41 after the first conveying belt 21 stops when the member state determination unit 111D determines that the member C is full in a state where the vibrator 41 vibrates and the member C is conveyed by the conveying member 42.

The component state determination unit 111D determines whether or not the component C is present in the conveyance component 42 based on the detection data of the component sensor 130. The motor control unit 111A stops the motor 24 when the component state determination unit 111D determines that the component C is not present in a state where the motor 24 is rotating and the conveying surface 210 of the 1 st conveying belt 21 is moving forward. The vibrator control unit 111B stops the vibrator 41 at the same timing as the stop of the motor 24 when the member state determination unit 111D determines that the member C is not present in a state where the vibrator 41 vibrates and the member C is conveyed by the conveying member 42.

The notification control unit 111E outputs a control command for controlling the notification device 150. The notification control unit 111E operates the notification device 150 when the motor state determination unit 111C determines that the state of the motor 24 is abnormal. In the embodiment, when determining that the state of the motor 24 is abnormal, the notification control unit 111E blinks the lamp of the notification device 150.

[ component supply method ]

Fig. 22 is a flowchart showing a component supply method according to the embodiment. The operator drops a plurality of scattered components C to the drop position IP through the opening 9. After the component C is thrown into the throw-in position IP, the supply of the component C from the throw-in position IP to the pickup position PP is started. The motor control unit 111A controls the motor 24 so that the conveying surface 210 of the 1 st conveyor belt 21 moves forward (step SA 1).

The 1 st conveyor belt 21 is driven, and the component C put into the position IP is conveyed to the supply position SP. The component C conveyed to the supply position SP is supplied to the delivery position RP of the conveying member 42.

The vibrator control section 111B controls the vibrator 41 so that the conveying member 42 vibrates (step SA 2).

The conveying member 42 is vibrated, whereby the member C supplied to the intersection position RP is conveyed to the 1 st sort section 60. The 1 st sorting unit 60 passes only the components C in the 1 st posture one by one. The 1 st sorting section 60 drops the component C not in the 1 st posture to the retreat position JP of the 2 nd conveying belt 22. The component C having passed through the 1 st sorting unit 60 is conveyed to the 2 nd sorting unit 70. The 2 nd sorting unit 70 passes only the component C in the 2 nd posture. The 2 nd sorting section 70 drops the component C not in the 2 nd posture to the retreat position JP of the 2 nd conveying belt 22. The component C having passed through the 2 nd sorting section 70 is conveyed to the direction setting section 80. The direction setting unit 80 adjusts the component C passing through the 2 nd sorting unit 70 to the 3 rd posture. The component C adjusted to the 3 rd posture is conveyed to the pickup position PP. The component C dropped to the retreat position JP of the 2 nd conveyor belt 22 is conveyed to the return position TP by the 2 nd conveyor belt 22, and then returned to the input position IP by the

return guide portions

23 and 33.

The rotation sensor 120 detects the state of the motor 24. The rotation sensor 120 detects the slit plate 121, thereby detecting the state of the motor 24. The component sensor 130 detects the state of the component C in the conveying component 42. The motor state determination unit 111C acquires detection data of the rotation sensor 120. The component state determination unit 111D acquires detection data of the component sensor 130 (step SA 3).

The motor state determination unit 111C determines whether or not the state of the motor 24 is abnormal based on the detection data of the rotation sensor 120 (step SA 4).

If it is determined in step SA4 that the state of the motor 24 is not abnormal (No in step SA4), the component state determination unit 111D determines whether or not the state of the component C is full based on the detection data of the component sensor 130 (step SA 5).

If it is determined in step SA5 that the component C is not fully loaded (step SA 5: No), the supply of the component C from the drop-in position IP to the pickup position PP is continued.

In the embodiment, when it is determined at step SA5 that the component C is not present on the conveyance component 42, the motor control unit 111A stops the motor 24. The vibrator control unit 111B stops the vibrator 41 at the same timing as the stop of the motor 24. The notification control unit 111E operates the notification device 150 so as to notify that the component C is not present.

If it is determined at step SA4 that the state of motor 24 is abnormal (step SA 4: Yes), motor control unit 111A stops motor 24 (step SA 6).

Further, the notification control unit 111E operates the notification device 150 to notify that the motor 24 is abnormal (step SA 7).

If it is determined at step SA5 that the component C is fully loaded (step SA 5: Yes), the motor controller 111A controls the motor 24 to stop after the conveying surface 210 of the 1 st conveying belt 21 moves backward (step SA 8).

In the embodiment, when it is determined that the state of the component C is full, the motor control unit 111A is instantaneously changed from the state in which the conveying surface 210 of the 1 st conveying belt 21 moves forward to the state in which it moves backward. The distance for moving the conveying surface 210 of the 1 st conveyor 21 backward is small. The motor control unit 111A controls the motor 24 so that the conveying surface 210 moves backward by a distance of, for example, 1 [% ] to 10 [% ] of the circumferential length of the 1 st conveyor belt 21. The circumference of the 1 st conveyor belt 21 refers to the length of the 1 st conveyor belt 21 of the endless belt. After the conveying surface 210 slightly moves backward, the motor control unit 111A stops the rotation of the rotor of the motor 24 to stop the driving of the 1 st conveyor belt 21.

In step SA8, after the driving of the 1 st conveyor belt 21 is stopped, the vibrator control unit 111B stops the vibrator 41 (step SA 9).

[ method of replacing parts ]

Fig. 23 is a flowchart showing a component replacement method according to the embodiment. When the component C housed in the housing 11 is replaced, the operator operates the operation device 140 to stop the motor 24 when the motor 24 is driven. If the operation device 140 is operated, the motor 24 is stopped by the motor control section 111A (step SB 1).

After the motor 24 is stopped, the operator removes the cover 97 from the housing 11 to open the opening 90, as described with reference to fig. 18 and 19. The opening 90 is opened, so that the operator can discharge the component C accommodated in the housing 11 to the outside of the housing 11 through the opening 90. The opening 90 is provided behind the inclined surface portion 211 of the 1 st conveyor belt 21. The inclined surface portion 211 is inclined upward from the input position IP toward the front.

After opening 90 is opened, the operator operates operation device 140. The operation device 140 is operated by an operator to generate an operation signal. An operation signal of the operation device 140 is output to the control device 110. The motor control unit 111A acquires an operation signal of the operation device 140 (step SB 2).

The motor control unit 111A controls the motor 24 based on the operation signal of the operation device 140 so that the conveying surface 210 of the 1 st conveying belt 21 moves backward (step SB 3).

The conveying surface 210 of the 1 st conveyor 21 moves backward, and the components C remaining on the 1 st conveyor 21 are discharged from the opening 90 to the outside of the housing 11.

After all the components C accommodated in the housing 11 are discharged, the operator can drop a new component C to the drop position IP. This allows the component C housed in the housing 11 to be replaced.

[ Effect ]

As described above, according to the embodiment, the feeder 10 includes: a1 st conveyor belt 21 that conveys the component C thrown into the throw-in position IP forward; and a conveying member 42 which is vibrated by the vibrator 41, conveys the component C from the 1 st conveying belt 21 forward, and supplies the component C to the pickup position PP of the mounting head 5. The conveying path of many components C is ensured by the 1 st conveying belt 21 and the conveying member 42. The first conveyor belt 21 and the conveying member 42 are arranged in the front-rear direction, thereby suppressing an increase in the size of the feeder 10 in the left-right direction. By suppressing the size of the feeders 10 in the left-right direction (the width of the feeders 10), the number of feeders 10 that can be loaded in the feeder receiver 8 can be increased. By suppressing the reduction in the number of feeders 10 that can be mounted on the feeder receiver 8, it is possible to suppress the reduction in the types of components C when the components C are scattered and supplied to the component mounting device 1. Further, the component C can be conveyed to the pickup position PP by the conveying component 42 by a conveying method equivalent to that of the bowl feeder.

Between the input position IP and the pickup position PP, a sorting unit 50 is provided through which only the component C in the predetermined posture passes. The feeder 10 can convey only the component C in the predetermined posture to the pickup position PP by the sorting section 50.

The sorting section 50 drops the component C not in the predetermined posture to the retreat position JP of the 2 nd conveying belt 22 disposed adjacent to the 1 st conveying belt 21. The 2 nd conveyor belt 22 conveys the component C in the direction opposite to the conveying direction of the 1 st conveyor belt 21.

Return guide portions

23 and 33 are provided for guiding the component C conveyed by the 2 nd conveyor belt 22 to the input position IP. Thereby, the component C dropped to the retracted position JP is returned to the input position IP. The 2 nd conveyor belt 22 is disposed adjacent to the 1 st conveyor belt 21. This suppresses an increase in the size of the feeder 10 in the front-rear direction.

The height of the conveying surface 220 of the 2 nd conveyor 22 at the return position TP is higher than the height of the conveying surface 210 of the 1 st conveyor 21 at the input position IP. The

return guide portions

23 and 33 drop the component C conveyed by the 2 nd conveyor 22 to the input position IP of the 1 st conveyor 21. This suppresses the stagnation of the component C in the 2 nd conveying belt 22. Therefore, the component C is smoothly fed from the 2 nd conveying belt 22 to the 1 st conveying belt 21.

The conveying speed of the 1 st conveyor belt 21 is higher than that of the 2 nd conveyor belt 22. This suppresses the retention of the component C in the 1 st conveyor belt 21. Therefore, the component C is smoothly fed from the 2 nd conveying belt 22 to the 1 st conveying belt 21.

The predetermined postures of the component C include the 1 st posture and the 2 nd posture. The sorting unit 50 includes: a1 st sorting unit 60 that passes only the components C in the 1 st posture one by one; and a2 nd sorting part 70 that passes only the component C in the 2 nd posture. By providing the 1 st sorting unit 60 and the 2 nd sorting unit 70 as the sorting unit 50, the sorting unit 50 can pass the component C in the 1 st posture and the 2 nd posture while suppressing complication of the structure of the 1 st sorting unit 60 and the 2 nd sorting unit 70.

The component C has a body D and a lead E protruding from the body D. The 1 st posture of the component C includes a posture in which the vertical dimension of the component C is smallest. The 2 nd posture of the component C includes a posture in which the lead E protrudes from the body D to the right in a specified direction. Thus, even when the component C has the lead E, the sorting unit 50 can pass the component C in the 1 st posture and the 2 nd posture.

A direction setting part 80 for adjusting the component C passing through the sorting part 50 to the 3 rd posture is provided. Thereby, the component C in the 3 rd posture is supplied to the pickup position PP.

The 3 rd position of the component C includes a position in which the lead E protrudes downward from the body D. Thereby, the mounting head 5 can hold the upper surface Da of the main body D by the suction nozzle 4 at the pickup position PP.

At the boundary between the 1 st conveyor belt 21 and the conveying member 42, the height of the conveying surface 210 of the 1 st conveyor belt 21 is higher than the height of the conveying surface 420 of the conveying member 42. This allows the scattered components C to be smoothly transferred from the 1 st conveyor belt 21 to the conveying member 42.

An opening 90 is provided in the housing 11 that houses the 1 st conveyor belt 21. The opening 90 faces the drop position IP. The opening 90 is opened and closed by a cover 97. When the component C existing at the input position IP of the housing 11 is discharged to the outside of the housing 11, the cover 97 is removed from the housing 11 to open the opening 90, whereby the component C is smoothly discharged to the outside of the housing 11.

The conveying surface 210 of the 1 st conveyor belt 21 includes a slope 211 inclined upward from the input position IP toward the front. The opening 90 is disposed behind the inclined surface portion 211. The opening 90 is opened, whereby the component C is smoothly discharged to the outside of the housing 11.

The operation device 140 is operated, thereby controlling the motor 24 to move the conveying surface 210 of the 1 st conveyor belt 21 rearward. The conveying surface 210 of the 1 st conveyor 21 moves backward, and the components C remaining on the 1 st conveyor 21 are discharged from the opening 90 to the outside of the housing 11.

In the case of a maladjustment of the motor 24, the motor 24 is stopped. For example, in the case of clamping the component C between the 1 st conveyor belt 21 and the housing 11, or clamping the component C between the 1 st conveyor belt 21 and the conveying member 42, the possibility of the motor 24 being out of order becomes high. When the motor 24 is out of order, if the driving of the motor 24 is continued and the driving of the 1 st conveyor belt 21 is continued, the component C and the 1 st conveyor belt 21 rub against each other, and there is a possibility that the 1 st conveyor belt 21 is worn out. Likewise, for example, in a state where the component C is sandwiched between the 2 nd conveyor belt 22 and the housing 11, if the driving of the 2 nd conveyor belt 22 is continued, there is a possibility that the 2 nd conveyor belt 22 is worn out. A rotation sensor 120 is provided for detecting a step-out of the motor 24. When it is determined that the motor 24 is out of order based on the detection data of the rotation sensor 120, the motor 24 is stopped. This suppresses wear of the 1 st conveyor belt 21 and wear of the 2 nd conveyor belt 22.

If the state of the motor 24 is abnormal, the notification device 150 operates. This allows the operator to recognize that the motor 24 is out of order.

When it is determined that the component C is fully loaded in the conveying member 42 and is not smoothly conveyed in a state where the conveying surface 210 of the 1 st conveyor 21 moves forward, the motor 24 is controlled so that the conveying surface 210 of the 1 st conveyor 21 slightly moves backward. The 1 st conveyor belt 21 moves in the reverse direction, and thus even in a case where the component C is sandwiched between the 1 st conveyor belt 21 and the conveying member 42, the component C is discharged from between the 1 st conveyor belt 21 and the conveying member 42. When the conveying surface 210 of the 1 st conveyor 21 slightly moves backward, the driving of the 1 st conveyor 21 is stopped, and the supply of the component C from the 1 st conveyor 21 to the conveying member 42 is stopped. Thereby, the state in which the component C is full in the conveying member 42 is eliminated.

When it is determined that the component C is filled in the conveying member 42 and is not conveyed smoothly, the vibration of the vibrator 41 is stopped after the driving of the 1 st conveying belt 21 is stopped. Thus, the member C of the conveying member 42 moves forward in a state where the supply of the member C from the 1 st conveying belt 21 to the conveying member 42 is stopped. Therefore, the state in which the component C is full in the conveying member 42 is eliminated.
