FIG. 9 is an explanatory diagram showing the electrical connection relationship of the control device 70. As shown in FIG.

The work supply device 10 supplies a disk-shaped or annular work W to a work robot (not shown) that performs a predetermined work. Here, the workpiece W is a washer member such as a plain washer or a spring washer in this embodiment. Also, in this embodiment, the working robot is a vertical articulated robot in which a gripping tool for gripping a washer member is attached to the tip arm as an end effector. This working robot grips a washer member supplied by the work supply device 10 and inserts the gripped washer member into the screw shaft of the aligned screw with the screw head facing downward.

As shown in FIGS. 1 and 2, the work supply device 10 includes a base 11, a hopper case 20, a rotating disk 30, a transport path 40, a transport device 50, a delivery device 60, and a control device 70 ( See FIG. 9).

The hopper case 20 is a case that can accommodate a large number of works W, and is fixed to the base 11 . The work W may be carried into the hopper case 20 by an operator, or may be automatically carried out by a carry-in device (not shown). The hopper case 20 has a bottom portion 21 and a wall portion 22 erected from the outer peripheral edge of the bottom portion 21, as shown in FIG. The bottom portion 21 is formed by an inclined surface. In addition, as shown in FIG. 4, the bottom portion 21 is formed with a circular concave portion 21d having an outer diameter slightly larger than the outer diameter of the rotating disk 30. As shown in FIG. An opening 21o as a through hole is formed at a position above the bottom surface of the recess 21d in the direction of inclination.

The rotating disk 30 is a thin disk-shaped member. The rotating disk 30 is rotatably arranged in the recess 21d, and the surface of the rotating disk 30 is slightly recessed from the inclined surface around the recess 21d as shown in FIGS. . A pulley 34 is coaxially attached to the rear surface of the rotating disk 30, as shown in FIG. A rotating shaft of a drive motor 36 is connected to the pulley 34 via a belt 35 . The rotating disk 30 is rotated clockwise in FIG. 3 by a driving motor 36 .

In addition, a plurality of (for example, six) pockets 32 as circular through holes are formed in the outer peripheral portion of the rotating disk 30 at equal intervals in the circumferential direction. Each pocket 32 has an outer diameter slightly larger than the outer diameter of the washer member so that the washer member as the work W can be fitted therein. Each pocket 32 moves in the circumferential direction as the rotary disk 30 is driven to rotate by the drive motor 36, and as shown in FIG. It communicates with an opening 21o formed in the .

Further, guide ribs 33 are formed on the surface of the rotating disk 30 and extend obliquely and linearly with respect to the tangential direction of the rotating disk 30 from the vicinity of the central portion to the front of the outer peripheral edge. As shown in FIG. 3, the guide rib 33 is formed at a position on the upstream side in the rotation direction of the rotating disk 30 with respect to the pocket 32 to be guided, and guides the work W to the outer peripheral edge of the rotating disk 30 to align the work W. In this state, it is guided to the pocket 32 to be guided. In this embodiment, a plurality of (for example, three) guide ribs 33 are formed at equal intervals in the circumferential direction.

A brush member 25 is provided in close proximity to the surface of the rotating disk 30, as shown in FIG. The brush member 25 is fixed to the wall portion 22 of the hopper case 20 via a bracket 24 so that the tip of the brush member 25 is close to the surface of the rotating disk 30 with a small gap. As a result, the brush member 25 allows the work W fitted in the pocket 32 to pass through, but prevents other works W from passing through. Therefore, since excess work W is not carried upward in the tilting direction of the rotating disk 30, it is possible to prevent a plurality of works W from being concentrated and stacked in the opening 21o.

In this manner, the workpieces W stored in the hopper case 20 are fitted into the pockets 32 by the guide ribs 33 below the rotating disk 30 in the inclination direction. When the work W is fitted in the pocket 32, the work W is pulled upward in the tilt direction by the rotation of the rotating disk 30. As shown in FIG. Then, when the pocket 32 reaches a predetermined position P above in the inclination direction, the work W drops with the pocket 32 communicating with the opening 21o of the bottom 21 (recess 21d).

As shown in FIGS. 5 to 8, the transport path 40 is a straight path, and has side walls 41 and 42 and an upper wall 43 (see FIG. 5) which are spaced apart from each other. A receiving area 40 a is provided on the upstream side of the transport passage 40 to receive the workpiece W dropped from the opening 21 o of the hopper case 20 . The interval between the side walls 41 and 42 is adjusted so that the width of the passage is slightly larger than the outer diameter of the workpiece W except for the receiving area 40a. The interval between the side walls 41 and 42 can be changed according to the size of the workpiece W. As shown in FIG. The upper wall portion 43 is arranged so that the conveying passage 40 has a tunnel shape except for the receiving area 40a. The upper wall portion 43 is arranged to have a size matching the passage width. As a result, the work W on the transport path 40 is prevented from jumping out of the path during transport. A transport end (downstream end) of the transport passage 40 is provided with a buffer sensor 48 for detecting that a work W is waiting at the transport end. The buffer sensor 48 can be composed of, for example, a transmissive photoelectric sensor having a light projecting section and a light receiving section which are arranged to face each other with the conveying end interposed therebetween.

The conveying device 50 conveys the work W dropped into the receiving area 40a of the conveying passage 40 from the upstream side to the downstream side along the conveying passage 40 by blowing air. As shown in FIGS. 6 to 8, the conveying device 50 supplies air to a first air blowing portion 51, a second air blowing portion 52, a third air blowing portion 53, and air blowing portions 51 to 53. and a carrier air supply mechanism 55 (see FIG. 2). The first air blowing portion 51 is arranged to blow air along the conveying path 40 from the upstream side toward the downstream side. The second and third air blowing portions 52 and 53 are arranged so as to blow air obliquely with respect to the conveying direction of the workpiece W from the side of the conveying path 40 . The conveying air supply mechanism 55 has a conveying switching valve (solenoid valve) connected to an externally installed air supply source (not shown) and each of the air blowing portions 51 to 53, and the conveying switching valve is turned on and off to control the supply of air to each of the air blowing portions 51-53. In addition, each of the paths of the air directed to each of the air blowing portions 51 to 53 of the conveying air supply mechanism 55 is provided with a throttle, and the blowing amount of the air becomes the blowing amount corresponding to the workpiece W by the throttle. is adjusted to By using the conveying device 50 as described above, the work W dropped into the receiving area 40 a of the conveying passage 40 first gains thrust from the air blown from the first air blowing portion 51 and advances along the conveying passage 40 . When the work W progresses halfway through the conveying passage 40, it is also thrust by the air blown by the second air blowing portion 52 and the air blown by the third air blowing portion 53, so that the work W is sufficiently thrust to reach the conveying end. can proceed.

The transfer device 60 is provided at the transfer end of the transfer passage 40, receives the work W transferred from the transfer end, and transfers the work W to a work robot (not shown). The transfer device 60 includes a table 61 having a receiving portion 61a capable of receiving only one workpiece W, a first position (see FIG. 6) where the receiving portion 61a is connected to the conveying end of the conveying path 40, and the receiving portion 61a. and a separating cylinder (air cylinder) 65 for moving the table 61 between a second position (see FIG. 7) where the table 61 is separated from the conveying end of the conveying path 40 . The bottom surface of the receiving portion 61 a is formed so as to be substantially flush with the bottom surface of the transport passage 40 . In addition, the surface of the table 61 facing the transport path 40 is provided with a wall portion 61b formed so as to be one step higher than the bottom surface of the transport path 40 except for the receiving portion 61a. Therefore, when the next work W is transported while one work W is received in the receiving portion 61a of the table 61, the next work W collides with the work W already received in the receiving portion 61a. and stops at the conveying end of the conveying path 40 . Further, when the next work W is transported while the receiving portion 61a is separated from the transport passage 40, the next work W collides with the wall portion 61b of the table 61 as shown in FIG. Stop at the transport end of the path 40 . The disconnecting cylinder 65 is connected to an air supply source via a disconnecting cylinder solenoid valve 66 (see FIG. 2), and moves the table 61 between the first position and the second position by supplying and discharging air. The delivery device 60 also has a work arrival sensor 68 for detecting that the work W has arrived at the table 61 . The work arrival sensor 68, like the buffer sensor 48, can be composed of, for example, a transmissive photoelectric sensor having a light projecting part and a light receiving part arranged to face each other with the receiving part 61a interposed therebetween.

The control device 70 is configured as a microprocessor centering on a CPU, and is provided with a ROM, a RAM, an input/output port, a communication port, etc., in addition to the CPU. As shown in FIG. 9, a detection signal from the buffer sensor 48, a detection signal from the work arrival sensor 68, and the like are input to the control device 70 through an input port. From the control device 70, a drive signal to the drive motor 36, a drive signal to the transfer air supply mechanism (solenoid valve) 55, a drive signal to the solenoid valve 66 for the separation cylinder, etc. are output via the output port. . The control device 70 also exchanges signals with the control device of the working robot via a communication port (not shown).

Next, the operation of the work supply device 10 configured in this manner will be described. In particular, the operation of transferring a large number of works W accommodated in the hopper case 20 by the transfer device 60 and the operation of transferring the works W received by the transfer device 60 to another will be described.

FIG. 10 is a flow chart showing an example of the transport control process. This process is repeatedly executed every predetermined time (for example, every several milliseconds or several tens of milliseconds). When the transport control process is executed, the controller 70 first determines whether the buffer sensor 48 is on (whether the work W is waiting at the transport end of the transport passage 40) (step S100). When the control device 70 determines that the buffer sensor 48 is not turned on, it drives the drive motor 36 (step S110) and drives the transfer air supply mechanism 55 (opens the transfer switching valve) (step S110). S120), the transport control process is terminated. On the other hand, if it is determined that the buffer sensor 48 is ON, the drive motor 36 is stopped (step S130), and the transfer air supply mechanism 55 is stopped (the transfer switching valve is closed) (step S140). Terminate the transport control process. As described above, the next work W is conveyed while the work W is received in the receiving portion 61 a of the table 61 , or the next work W is conveyed while the receiving portion 61 a is separated from the conveying path 40 . However, the next work W is not received by the receiving portion 61a and waits at the conveying end of the conveying path 40. As shown in FIG. Therefore, by stopping the drive motor 36 and the transfer air supply mechanism 55 so as to stop the transfer of the work W in such a situation, the drive motor 36 and the transfer air supply mechanism 55 are constantly driven. As a result, wasteful driving can be suppressed, and noise can be reduced and energy can be saved.

FIG. 11 is a flow chart showing an example of delivery processing. This process is repeatedly executed every predetermined time (for example, every several milliseconds or several tens of milliseconds). When the delivery process is executed, the control device 70 first determines whether or not the receiving portion 61a of the table 61 is separated from the transport passage 40 (step S200). When the control device 70 determines that the receiving portion 61a is not separated from the conveying passage 40 and the table 61 is waiting at the first position, it determines whether the work W has arrived at the receiving portion 61a (the work arrival sensor 68 is turned on). (step S210). When the control device 70 determines that the work arrival sensor 68 is turned off, the work W has not arrived, so the delivery process is once terminated. When the control device 70 determines that the work arrival sensor 68 is turned on, the table 61 moves to the second position and the receiving section 61a moves to the second position in order to transfer the work W received by the receiving section 61a to the working robot. The solenoid valve 66 for the disconnection cylinder is controlled so as to be disconnected from the transfer passage 40 (step S220). The control device 70 then transmits a signal to the effect that preparation of the work W is completed to the control device of the working robot (step S230), and ends the delivery process. As a result, the working robot can work on the workpiece W. As shown in FIG. On the other hand, when the control device 70 determines in step S200 that the receiving portion 61a is separated from the conveying path 40 and the table 61 has moved to the second position, has the work W been taken out from the receiving portion 61 (Work Arrival? It is determined whether or not the sensor 68 is turned off (step S240). When the control device 70 determines that the work arrival sensor 68 is turned on, the work W has not been taken out, so the delivery process is once terminated. When the control device 70 determines that the work arrival sensor 68 is turned off, it determines that the work W has been taken out by the work robot, and moves the table 61 to the first position to receive the next work W in the receiving portion 61a. The disconnecting cylinder solenoid valve 66 is controlled so that the receiving portion 61a is moved and connected to the transport passage 40 (step S250), and the delivery process is terminated.

The work supply device 10 of this embodiment described above includes a hopper case 20 capable of accommodating a large number of works W, and a rotating disk 30 provided on the bottom portion 21 of the hopper case 20 . The hopper case 20 has a bottom portion 21 formed with an inclined surface and an opening portion 21o formed in the bottom portion 21 . The rotating disk 30 is provided along the inclined surface of the bottom portion 21 and has a pocket 32 in which the workpiece W is fitted in the outer peripheral portion. Further, when the pocket 32 moves to a predetermined position P upward in the inclination direction as the rotating disk 30 rotates, it communicates with the opening 21o. As a result, when the work W stored in the hopper case 20 is fitted into the pocket 32 of the rotating disk 30, the rotating disk 30 rotates and pulls it upward in the inclined direction. Then, when the pocket 32 moves to a predetermined position P upward in the inclination direction, the work W is received on the upstream side of the conveying passage 40 through the opening 21o through which the pocket 32 communicates with the opening 21o of the hopper case 20. It is sent to area 40a. In this way, after the work W is fitted into the pocket 32 of the rotating disk 30, the work W is once lifted upward in the inclined direction, and then sent to the conveying passage 40 through the opening 21o of the bottom 21 of the hopper case 20. Therefore, it is possible to prevent a plurality of works W from being concentrated and stacked in the opening 21o. As a result, the work supply device 10 can feed and supply the works W one by one to the conveying path 40 without stacking the works W in the middle.

Further, in the work supply device 10 of the present embodiment, the works W are aligned on the outer peripheral edge of the rotating disk 30 on the surface of the rotating disk 30 at a position on the upstream side in the rotation direction of the rotating disk 30 with respect to the pocket 32 . A guide rib 33 is provided to guide into the pocket 32 . As a result, the rotating disc 30 can more reliably fit one workpiece W into the pocket 32 .

Further, the work supply device 10 of the present embodiment is provided so as to be close to a position on the upstream side in the rotation direction of the rotary disc 30 with respect to the position corresponding to the opening 21o of the rotary disc 30, and is fitted into the pocket 32. A brush member 25 is provided which allows the work W to pass through but does not allow the other work W to pass through. As a result, it is possible to prevent the excess work W from being supplied to the opening 21o, and to more reliably suppress the work W from stacking in the opening 21o.

Further, in the work supply device 10 of the present embodiment, the conveying device 50 includes the first air blowing portion 51 that blows air along the conveying passage 40 from the upstream side toward the downstream side. Thus, the work W sent to the receiving area 40a of the transport path 40 can be transported along the transport path 40 with a simple configuration. In addition, the conveying device 50 includes a second air blowing portion 52 and a third air blowing portion 53 that blow air obliquely to the conveying direction from the side of the conveying passage 40 . As a result, the conveying device 50 can impart a sufficient thrust to the work W even on the downstream side of the conveying passage 40 and convey the work W smoothly.

Further, the work supply device 10 of this embodiment includes a transfer device 60 which has a receiving portion 61a for receiving the work W from the transfer end of the transfer passage 40 and transfers the received work W to another, and A buffer sensor 48 for detecting a waiting work W and a control device 70 are provided. The control device 70 stops the rotating disk 30 (driving motor 36) and the conveying device 50 (conveying air supply mechanism 55) when the work W is detected by the buffer sensor 48. FIG. As a result, the work supply device 10 can reduce unnecessary driving, reduce noise, and save energy, compared to a device that constantly drives the rotating disk 30 and the transport device 50 .

It goes without saying that the present invention is not limited to the above-described embodiments, and can be embodied in various forms as long as they fall within the technical scope of the invention disclosed herein.

For example, in the embodiment described above, the rotating disk 30 is provided with a plurality of (six) pockets 32 on the outer peripheral portion, but it may be provided with only one pocket 32 . Further, although the rotary disk 30 is provided with the guide ribs 33 for guiding the workpieces W in alignment with the pockets 32, the guide ribs 33 may be omitted.

In the embodiment described above, the tip of the brush member 25 is provided so as to approach the surface of the rotating disk 30 with a small gap. However, the brush member 25 may be provided so that the tip thereof contacts the surface of the rotating disk 30 . Further, the work supply device 10 may be provided with a scraper member provided so that the tip is close to the surface of the rotating disk 30 instead of the brush member 25 . Also, the brush member 25 and the scraper member may be omitted.

In the embodiment described above, the conveying device 50 is provided with the second air blowing portion 52 and the third air blowing portion 53 in addition to the first air blowing portion 51 . However, the conveying device 50 may omit the second air blowing portion 52 and the third air blowing portion 53 depending on the length of the conveying passage 40 . Further, although the conveying device 50 conveys the work W by blowing air, the conveying device 50 may convey the work W by negative pressure.

In the above-described embodiment, when the buffer sensor 48 detects the work W waiting at the transport end of the transport passage 40, the control device 70 controls the rotating disk 30 (driving motor 36) and the transport device 50 (transport air). The supply mechanism 55) is to be stopped. However, when the buffer sensor 48 detects the work W waiting at the conveying end of the conveying path 40 and the work arrival sensor 68 detects the work W received in the receiving section 61a, the control device 70 rotates. The disk 30 and the carrier device 50 may be stopped. Alternatively, the control device 70 may always drive the rotating disk 30 and the transport device 50 regardless of detection by the buffer sensor 48 or the work arrival sensor 68 .
