The third sensor 116 is mounted close to the downstream end of the second conveyor 40 and has a poor posture from the second conveyor 40 to the guide chute 68, i.e., the parts 2 with respect to their conveying direction. The control unit 110 outputs a signal that detects the parts 2 that are turned over without maintaining an orthogonal posture and inputs the signal to the controller 110. The controller 110 processes signals input from the first to third sensors 112, 114, and 116, respectively, so that the motor 30 of the first conveyor 20, the motor 54 of the second conveyor 40, The driving of the servomotor 84 of the linear actuator 80 and the motor 104 of the tilting device 100 is sequence controlled.

The operation of the component supply apparatus according to the present invention having such a configuration will now be described.

1, 2 and 6, when a large amount of parts 2 are inserted upstream of the hopper 32, the parts 2 introduced into the hopper 32 are inclined by their own weight 28. Is concentrated upstream. When the motor 30 of the first conveyor 20 is driven, the driving force of the motor 30 is transmitted to the motor pulley 24 by the belt transmission device 34, and the motor pulley by the rotation of the motor pulley 24. The belt 28 wound around the 24 and the driven pulley 26 is conveyed. The parts 2 are received one by one in the grooves 28a of the belt 28 and are transported from the first position P1 upstream to the second position P2 downstream.

6 and 7, the parts 2 received and transported in the grooves 28a of the belt 28 escape from the grooves 28a downstream of the belt 28 from the feed belt 28b. Departed, the departed parts 2 are turned over to the belt 52 of the second conveyor 40. The parts 2 received in the feed belt 52b of the belt 52 are slid by their own weight in the inclined section S1 and concentrated upstream of the feed belt 52b.

The first sensor 112 outputs a signal detected by the components 2 supplied upstream of the feed belt 52b and inputs it to the controller 110. The controller 110 processes the signal input from the first sensor 112 so that the components 2 can be loaded at least one lot 2, i.e., more than the set quantity upstream of the feed belt 52b. When it is determined that the supply is made, the driving of the motor 30 is stopped to stop the operation of the first conveyor 20. Thus, the parts 2 supplied to the belt 52 of the second conveyor 40 by supplying the parts 2 to the second conveyor 40 in the set quantity by the operation of the first conveyor 20. It is possible to transfer the parts 2 accurately and stably by preventing a transfer error due to their overload.

1, 2 and 7, when the motor 54 of the second conveyor 40 is driven, the motor pulley 44 is rotated by the driving of the motor 54. The belt 52 wound around the driven pulley 44 and the driven pulley 46 is transferred by the rotation of the driven pulley 44. The parts 2 are accommodated one by one in the grooves 52a of the belts 52 and then the first intermediate pulley 48 and the prime mover after the inclined section S1 between the driven pulley 46 and the first intermediate pulley 48. It is transferred to the horizontal section (S2) between the pulleys (44). The parts 2 which are not received in the correct position in the grooves 52a of the belt 52 are rolled up by the feed belt 52b by their own weight in the inclined section S1 and are collected again upstream. Therefore, by the operation of the second conveyor 40, the parts 2 are precisely aligned one by one and sequentially transferred.

Subsequently, the parts 2 carried on the feed belt 52b of the belt 52 are transferred to the downstream third position P3 through the horizontal section S2. Parts 2 received and transported in the grooves 52a of the belt 52 exit the grooves 52a at the downstream end of the belt 52 and are separated from the feed belt 52b, and the parts 2 are separated. ) Slides on the guide chute 68 and is turned over to the wheel 62 of the unloading wheel device 60. Since the wheel 62 is connected by the motive pulley 44 of the second conveyor 40 and the belt transmission device 68, the wheel 62 rotates with the conveyance of the belt 52. The parts 2 are sequentially received one by one in the grooves 62a of the wheel 62 which are rotated past the guide chute 68 and the parts 2 received in the grooves 62a are subjected to rotation of the wheel 62. It passes along the passage 64a and toward the exit 64b. The parts 2 are discharged through the outlet 64b while being separated from the grooves 62a, and the parts 2 discharged through the outlet 64b are aligned and received inside the cartridge 70.

The third sensor 116 is a component of poor posture such that the parts 2 taken over from the belt 52 to the guide chute 68 are not placed in a direction orthogonal to the conveying direction but are inclined to one side or placed in parallel with the conveying direction. The signals detected by (2) are input to the controller 110. When the controller 110 processes the signal input from the third parser 116 and determines that the postures of the components 2 are poor, the controller 110 stops driving of the motor 54 and the second conveyor 40 and the unloading wheel device. The operation of the 60 is stopped. When the operation of the second conveyor 40 and the unloading wheel device 60 is stopped, the operator removes the bad posture parts 2 placed on the guide chute 68 and then releases the buttons 110a of the controller 110. To operate the motor 54 again. Therefore, the parts 2 can be received and carried in the correct position in the grooves 62a of the wheel 62.

7 to 10, the second sensor 114 outputs a signal detecting the parts 2 accommodated in the cartridge 70 and inputs the signal to the controller 110. The controller 110 processes the signal input from the second sensor 114, and when it is determined that the predetermined number of parts 2 are accommodated in the cartridge 70, the servo motor of the lead actuator 80 84). The lead screw 86 is rotated by the driving of the servomotor 84, and the ball nut 88 is screwed along the lead screw 86 being rotated. The carrier 90 coupled with the ball nut 88 is linearly moved along the guide rail 82 to transport the cartridge 70 mounted on the holder 92. Thus, since the cartridge 70 is linearly moved with respect to the outlet 64b between the wheel 62 and the guide cover 64 by the operation of the lead actuator 80, the empty space of the cartridge 70 is discharged 64a. ), The parts 2 may be aligned and accommodated in the entire cartridge 70.

1 and 8 to 10, when the storage of the parts 2 for the cartridge 70 is completed, the motor 30 and the second of the first conveyor 20 are controlled by the controller 110. The motor 54 of the conveyor 40 is stopped. Next, when the motor 104 of the tilting device 100 is driven by the control of the controller 110, the eccentric wheel 106 is rotated about the shaft 108 by the driving of the motor 104. As shown in FIG. 9, the other end lower surface of the guide rail 82 is supported by the maximum eccentric outer surface portion 106a as the rotation of the eccentric wheel 106 is supported by the minimum eccentric outer surface portion 106b. One end of the guide rail 82 is hinged 102 while the other end surface of the guide rail 82 is supported from the maximum eccentric outer surface portion 106a of the eccentric wheel 106 to the minimum eccentric outer surface portion 106b. The pivot 70 is rotated about the pivot 102c, and the cartridge 70 is spaced apart from the wheel 62 in the standby position P4. Therefore, the operator can detach the cartridge 70 in which the parts 2 are stored from the holder 92, and then simply attach the empty cartridge to the holder 92.

Next, when the cartridge 70 is mounted on the holder 92 of the lead actuator 80, the eccentric wheel 106 is rotated by driving the motor 104 so that the other end lower surface of the guide rail 82 is the maximum eccentricity. The cartridge 70 is tilted to be supported by the outer surface portion 106a. Accordingly, the cartridge 70 is disposed in the storage position P5, which is close to the lower portion of the wheel 62 and can receive the components 2. After the operator randomly inserts a large amount of parts 2 into the hopper 32 of the first conveyor 20, the operator can continuously perform the alignment and supply of the parts 2 by setting the controller 110.
