Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts feeding apparatus.

2. Description of the Related Art For example, in a vibrating parts feeder, a spiral part transfer path is formed on the inner peripheral wall of a bowl that receives a large number of parts, and the torsional vibration of the bowl causes the part to travel along the transfer path. Although the parts are transferred, the transfer attitude of the parts is discriminated on the way, and based on this judgment, the parts which are not in the desired attitude by some part feeding means are moved outward from the transfer path, for example. It is widely known that it is blown into the bowl by compressed air, or is corrected to a desired posture, for example, it is corrected by a turntable so as to change the direction by 180 degrees and guided to the downstream transfer path. ing.

However, as a conventional device for discriminating the posture of a component, for example, a plurality of pairs of light emitting elements and light receiving elements are formed, and a small hole is formed through the transfer path to allow the light rays from each light emitting element to pass therethrough. A light receiving element is arranged to receive the light from the light emitting element. Among these, a pair of light emitting element and light receiving element are used for so-called synchronization, and when this light is blocked, the posture is determined. It is determined that the tip of the component to be reached has reached the detection position, and in the computer it is determined whether the light from the light emitting element corresponding to which light receiving element in the other pair of light emitting element and light receiving element at this time has arrived, As a result, as compared with the predetermined posture, when the posture is not the predetermined posture, the components are blown toward the inside of the bowl by the component adjusting means on the downstream side, for example, the air jetting means. Alternatively, when it is determined that the front-back direction is opposite, the posture is corrected to a correct posture by the component reversing means and the component is supplied to the downstream side.

However, there is no problem as long as the parts stored in the bowl are constant parts. However, if the above-mentioned operation is to be performed on parts having other shapes, the attitude of the parts should be judged. It is necessary to change the arrangement of a plurality of pairs of light emitting elements and light receiving elements in order to determine the posture. Or you have to change the number. Recently, since the components to be transported have become very small like electronic components, the work of arranging these light emitting element and light receiving element is very troublesome. Further, as the size of the component becomes smaller, a through hole must be formed in the transfer path to allow the light from the light emitting element to pass therethrough, but this is also small, and it is very difficult to form this.

In view of the above-mentioned problems, the applicant of the present invention can promptly deal with a change in the shape of a component immediately, and can correctly determine the posture of any shape or any small component. For the purpose of providing a parts feeding device in a vibrating parts carrier capable of
The following device has been proposed (Japanese Patent Laid-Open No. 4-7211).
issue).

The component feeding apparatus will be described below with reference to the drawings.

FIG. 8 and FIG. 9 show this conventional apparatus. In the figures, a spiral part transfer track 3 is formed on the inner peripheral wall of a bowl 2 of a vibrating parts feeder 1 and its discharge end is linear. It is supposed to be truck 4. From now on, the component m is supplied to the next process in a predetermined posture. A movable core 5 is integrally fixed to the bottom wall of the bowl 2, and is connected to a base block 6 by a leaf spring 7 arranged at equal angular intervals. An electromagnet 9 around which a coil 8 is wound is fixed on the base block 6. The vibrating parts feeder 1 is constructed as described above, but the whole is supported on the floor by the vibration-proof rubber 10.

A CCD camera 11 is provided at a predetermined position on the bowl 2.
The lens portion 11a is fixed to the bowl 2 by the mounting member 12 so that the lens portion 11a fits into the side wall portion of the bowl 2. Further, the lens part 11a captures an image of the part m transported in front of the camera. According to the conventional example, the camera 1
1, a light source 13 is arranged in front of the light source 1, so that the shadow of the component m is imaged. That is, the black level signal is picked up according to the shape.

On the downstream side of the CCD camera 11, an air ejecting device 14 is fixed to the bowl 2 in the vicinity thereof, and its nozzle portion 14a faces the track 3 and is desired by a computer as described later. The component m that is determined not to have the posture is configured to be blown into the bowl 2 by the compressed air. The solenoid valve 15 connected to this tube is controlled by a computer.

Next, an electric circuit connected to the CCD camera 11 will be described. The driving power is supplied from the driving circuit 20 to the coil 8 of the electromagnet 9 which is the driving unit of the vibrating parts feeder 1. This is an alternating current and is supplied to the synchronizing signal generating circuit 21 to generate a signal synchronized with this frequency. It is connected. This is further supplied to the image input control device 22 connected to the output terminal of the CCD camera 11, where C
Only the image synchronized with the vibration by the CD camera 11 is supplied to the computer 23. Ie CCD
According to this conventional example, the camera 11 performs an image pickup operation at a frequency higher than the drive frequency of the drive circuit 20, and therefore, when each image pickup signal and the sync signal from the sync signal generation circuit 21 are ANDed and they occur simultaneously. Computer 23 CCD
The image pickup signal of the camera 11 is supplied.
A predetermined attitude of the component m is stored in the computer 23 by operating various buttons, and this is compared with an image pickup signal supplied from the image input control device 22, and when they match, a solenoid valve connected to the computer 23. Although the solenoid portion of 15 is not driven, when it does not match, the solenoid portion is driven to supply compressed air to the air ejection device 14.

The component feeding device in the vibrating component carrier according to the conventional example is constructed as described above, and its operation will be described below.

In FIG. 8, the parts m are shown only in a scattered manner, but it is assumed that a large number of parts m are actually put therein. Further, in order to make the drawing easy to understand, the relative sizes of the bowl 2 and the component m are neglected in the drawing.
When the coil 8 is excited by the drive circuit 20, the drive circuit 2
At a drive frequency of 0, the bowl 2 undergoes torsional vibration, which causes the part m to be transported along the track 3 in the direction indicated by the arrow.

When coming in front of the lens portion 11a of the CCD camera 11, the light source 13 is irradiated with light and its shadow is imaged.
This shutter time is higher than the drive frequency of the bowl 2. This image pickup signal is supplied to the image input control device 22. On the other hand, the excitation signal of the coil 8 is supplied from the drive circuit 20 to the synchronization signal generation circuit 21, and the circuit 21 supplies the rectangular pulse synchronization signal to the image input control device 22. Here, it is synchronized with the image pickup signal from the CCD camera 11. That is, when the logical product is obtained and coincident, that is, only the synchronized imaging is supplied to the computer 23. Since a desired posture is stored in advance in the computer 23, the solenoid valve 1 is compared when compared with the desired posture.
Since the solenoid portion 5 is not excited at all, the component m passes through the front of the nozzle portion 14a as it is and is supplied to the next process through the track 4. If the computer 23 determines that they do not match, the solenoid portion of the solenoid valve 15 is excited, compressed air is ejected from the nozzle portion 14a, and the component m not in the predetermined posture is blown inward of the bowl 2. There is.

As described above, it is possible to supply only one part m having a predetermined posture to the next process, but the input operation of the predetermined posture in the computer 23 is performed by various buttons or by analog operation. Since it can be stored, it is possible to promptly deal with this even if the shape of the part changes. Further, even when the shape of the part whose posture should be determined is very small, the lens portion 11a of the CCD camera 11 is
The conventional example can be applied to any small-sized component because the image can be magnified by the magnifying action and imaged and compared in the computer 23. Further, even if the shape of the part is changed, only the input operation of the desired attitude to the computer 23 need be performed, so that the change in the shape of the part can be dealt with much more quickly than before.

However, in the above-mentioned component feeding apparatus, the CCD camera 11 is used as an image pickup device, which is fixed to the bowl 2 as shown in FIG. 8, and the shutter release timing of this camera is used. As is well known on the track of the vibrating parts feeder 1, the part m is transferred in a certain direction by repeating a periodic jumping motion. Since this jumping motion is periodic, it is integrated with the track. I try to release the shutter of the camera in the normal phase. Therefore, various control devices as shown in FIG. 10 are required. Therefore, a complicated circuit is required to set the timing for releasing the shutter of the camera, and since the camera 11 is fixed to the bowl 2, an unbalanced load may occur and the vibration mode of the bowl 2 may be non-uniform.

[0015]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and takes a timing to release the shutter of the camera without interfering with the vibration mode of the bowl of the vibrating parts feeder as the vibrating carrier. Therefore, an object of the present invention is to provide a parts feeding device that does not require a complicated control circuit.

[0016]

[Means for Solving the Problems] The above-mentioned object is to convey a component by vibrating along a predetermined transfer path, determine the transfer posture of this component, and based on this determination, move the component to a predetermined posture. In the parts aligning device which removes the parts not in the outside from the transfer path or corrects them to a desired posture and guides them to the transfer path on the downstream side, in the vicinity of the discharge end of the transfer path. Then, a belt conveyer and an image pickup device are provided in the vicinity of the side of the belt conveyer, and the posture of the component supplied from the discharge end is imaged on the belt conveyer,
When the images are compared with a desired posture previously stored in the computer, and when these do not match, the transfer component is driven outward by the partial feeding means, or the desired posture is obtained. This is achieved by a component feeding device characterized by being straightened.

Further, the above object is to convey a component by vibrating along a predetermined transfer path, determine the transfer posture of this component, and based on this determination, move the component that is not in the predetermined posture by the component aligning means. In a parts feeding device which is removed from the path outward or is corrected to a desired posture and guided to the transfer path on the downstream side, a cutout is formed in a part of the transfer path, and the cutout is formed. A belt conveyor and an image pickup device adjacent to the side of the belt conveyor are provided in the section, images of the postures of the components supplied from the upstream side of the transfer path are imaged on the belt conveyor, and the image pickup is performed in advance in a computer. Compared with the stored desired posture, when these do not match, the transfer path component is driven to the outside by driving the component feeding means or corrected to the desired posture. Achieved by a parts feeding device featuring It is.

[0018]

Since the notch is formed in the vicinity of the discharge end of the transfer path or in a part of the transfer path and the belt conveyor device is provided here, the transfer on the belt transferred above this is not vibration transfer. As the belt travels linearly, it is transferred to the chute of the next process or the transfer path on the downstream side, so the timing of the shutter of the image pickup device arranged close to this is set. Since the image pickup device is fixedly supported on the stationary part and not fixed to the vibrating carrier, for example, the bowl of the vibrating parts feeder, the vibration mode can be controlled by the image pickup device without requiring a complicated control circuit. It will not be damaged. Therefore, the posture of the component can be surely discriminated at low cost, and thereafter, the component which is not in the predetermined posture can be removed to the outside or brought into the predetermined posture by the correcting means and supplied to the next process.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A parts feeding apparatus according to embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show the parts feeding apparatus of the first embodiment. In the figures, this parts feeding apparatus is indicated by 40 as a whole, and mainly the vibrating parts feeder 4 is used.
1 and a belt conveyor device 42 connected to this discharge end
And a chute 43 arranged in the vicinity thereof. In the vibrating parts feeder 41, the bowl 44 is configured in the same manner as the conventional example, but the discharge end of the spiral track 45 is formed as a linear track 46, and the belt conveyor 42 has a slight gap in it. It is arranged in advance. The structure of the vibration parts feeder 41 is the same as the conventional one. Next, the belt conveyor device 42 will be described mainly with reference to FIG.

The belt 52 is wound around a driving roller 53 and a driven roller 54, and the driving roller 53 is driven by a motor 55. In this embodiment, the motor 55
The rotating shaft of is directly connected to the drive roller 53. An encoder 56 is concentrically attached to the shaft of the driven roller 54. The entire belt conveyor device 42 is attached to the frame 51, and is supported on the ground even though not shown. Therefore, it is vibrationally isolated from the vibrating parts feeder 41. A light source 57 and a CCD camera 58 as an image pickup device are arranged in proximity to the upstream end of the upper running portion of the belt 52 and facing the light source 57. Further, an air ejection nozzle 59 is arranged in the vicinity of the downstream end of the belt 52, which is connected to a compressor via a pipe 60 and a solenoid valve 61. Solenoid 61 of solenoid valve 61
Although not shown, a is connected to a control circuit and is configured to be excited by a command of a computer which receives the output of the CCD camera 58.

It is assumed that a predetermined posture of the parts n to be aligned and supplied in this embodiment is stored in a computer (not shown) by teaching.

At the downstream end of the belt conveyor device 42, a chute 43 is supported on the ground by a pillar 43a with a predetermined inclination as shown in FIG.

The component feeding apparatus of the present invention is constructed as described above. Next, its operation will be described.

In FIG. 1, it is assumed that a large number of parts n are stored in the bowl 44, though not shown. When this torsional vibration drive is excited, the part n is transferred by vibration along its track 45 and its linear discharge end 4
1 and is fed onto the belt 52 in the one-piece belt conveyor device 42 as shown in FIG. Since the track 46 as the discharge end of the track 45 of the bowl 44 of the vibrating parts feeder is inclined downward in the radially outer direction of the bowl 44, the track 46 is transferred while contacting the radially outer side wall portion, that is, the transfer posture. Are regulated so that the center line of the belt conveyor 52, that is, the center line of the belt conveyor, abuts one side wall portion of the track 46 and substantially coincides with the center line of the parts to be transferred, The light from the light source 57 arranged close to the upstream end is projected, and the CCD camera 58 captures this shadow. According to the present embodiment, the CCD camera 58 is configured as an area sensor, and is configured so that the part n is accommodated in the rectangular window, and the part n is inserted into the window and then predetermined. The shadow of the light source 57 of the component n is picked up after a lapse of time, and the picked-up image signal is supplied to a computer (not shown). Here, as compared with the desired posture stored in advance, when the desired posture is not obtained, air is ejected from the air ejection nozzle 59 arranged on the downstream side, and the air is ejected from the air ejection nozzle 59 to be integrated with the bowl 44. It is configured to be blown into the pocket 52. That is, when the solenoid portion 61a of the electromagnetic valve 61 is excited, air is ejected from the air ejection nozzle 59.

In the case where the chute 43 is in the predetermined posture, the computer judges that the posture is the predetermined posture, and the air ejection nozzle 59 disposed on the downstream side is not operated, and the chute 43 is placed on the chute 43 in the same posture. It is configured such that it is supplied, and slides here to be supplied to the next process one by one.

Since the CCD camera 58 is constructed and operates as described above, it is not necessary to fix the CCD camera 58 to the bowl 44. Therefore, the posture of the part n can be imaged without giving any interference to the vibration of the bowl 44. Those that are not in a predetermined posture can be discharged into the pocket 62. When the component whose shadow is captured by the CCD 56 by the encoder 56 is not in a predetermined posture, the excitation signal of the computer drives the solenoid 61a to eject air from the ejection nozzle 59 as described above. The part n is excluded from the pocket 62, but the air ejection timing of the air ejection nozzle 59 is transferred by this distance by the belt 52 being rotated to the air ejection nozzle 59 after being imaged by the encoder 56. The solenoid portion 61a is excited at the specified timing.

2 and 3 show a parts feeding device according to a second embodiment of the present invention, the whole of which is shown by 70, and this embodiment is mainly composed of a vibrating parts feeder. As in the first embodiment, a spiral track 72 is formed in the bowl 71, and the track portion 7 is provided as an attachment at the rear end of the discharge end.
3 is fixed. Therefore, this also performs torsional vibration and is conventionally formed integrally with the downstream side track portion 74 thereof, but in the present embodiment, the notch portion 6 is provided therebetween.
9 is formed, and the belt conveyor device 77 according to the present invention is arranged therein. This is configured similarly to the first embodiment, and a belt wound around a driving roller and a driven roller, and a light source 78 and a CCD camera 79, which are laterally opposed to each other, are provided at the upstream end of the belt. The drive roller is driven by the motor 80, and the driven roller is fixed with the encoder 82 as in the first embodiment. The air is ejected in the vicinity of the downstream end of the belt conveyor device 77. A nozzle 81 is arranged. The vibration transfer path 74 on the downstream side is fixed to the bowl 71 by a mounting member 75 with a slight gap at the downstream end of the belt conveyor device 77. Therefore, torsional vibration is integrally performed with the bowl 71. . A chute 83 is arranged on the downstream side track 74 with a slight gap.

The component feeding apparatus according to the second embodiment of the present invention is constructed as described above. Next, its operation will be described. Although not shown, this vibration parts feeder 7
When the torsional vibration drive unit of No. 0 is driven, the component n (not shown)
Is transferred by vibration along the track 71, is introduced into the upstream side track portion 73 close to this discharge end portion, is transferred from there to the upstream side end portion of the belt conveyor device 77, and is connected to the light source 78 and the CCD camera. When the shadow of this part is picked up at a predetermined timing when passing between 79, and this picked-up image signal is supplied to a computer (not shown) and does not match when compared with the part in the desired posture stored therein,
A signal for exciting the solenoid portion of the solenoid valve is generated from the computer, and thereby the nozzle 81 is operated to discharge a component, which does not have a predetermined posture and passes the side of the nozzle 81 in a predetermined rotation phase by the encoder 82, into the pocket 76. I am trying to do it.

When an image of a component in a predetermined posture is picked up, the solenoid portion of the solenoid valve is not excited. Therefore, the solenoid portion passes through the side of the nozzle 81 as it is, and is transferred to the track portion 74 on the downstream side. It can be vibrated and transferred by the torsional vibration, and can be supplied to the next process in a predetermined posture through the chute 83.

It is obvious that the same effect as that of FIG. 1 is also obtained in this embodiment.

One piece is supplied in a predetermined posture. Further, when the computer determines that the posture is not the predetermined posture, the solenoid portion 21 is passed when passing the side of the nozzle 210.
