Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply apparatus, and more particularly, to an aligning and conveying means for feeding out components in a hopper while aligning them along a guide, and a component receiving portion for conveying the components conveyed by the aligning and conveying means. While receiving in sequence,
The present invention relates to a component supply device provided with a transfer means that transfers a component after it has been received to the next process, sends it out each time, and supplies it to the next process.

[0002]

2. Description of the Related Art An apparatus of this type will be described with reference to FIGS. 1 and 2 showing an embodiment of the present invention. For example, an aligning and conveying means A utilizing a bowl type hopper 10 as shown in FIG.
Is a guide 2 provided along the peripheral wall 10a of the hopper 10 by vibrating the components housed in the hopper 10, for example.
2A to guide the excessive parts 1 and those in the non-aligned state into the hopper 10 as indicated by the broken line arrow a in FIG. ) Send it out as shown in. On the other hand, the transfer means B for transferring the parts 1 sent by the alignment transfer means A to the next step C shown in FIG. 1 and supplying the same to the next step C is, for example, the parts 1 supplied as shown in FIGS. The index table 4 is used for receiving the parts in the concave part receiving part 3 arranged on the outer peripheral part and transferring the parts 1 by the circular movement of the concave part receiving part 3.
The component 1 sent by the guide 2 is received in the component receiving concave portion 3 facing the tip of the guide 2 and is transported by a fixed amount while rotating intermittently, and is supplied to it every time the next step C is reached.

By the way, when the parts 1 conveyed by the aligning and conveying means A are cubes or rectangular parallelepipeds, even if the parts 1 are aligned along the guide 2, the front-back direction and front-back direction May not be constant.

For example, in the case of automatically supplying electronic components to an automatic component mounting machine or a component automatic mounting machine for automatically mounting or mounting a large number of electronic components on an electronic circuit board, it is convenient to automatically supply the components. It is said that the electronic components supplied in the next step C are sequentially accommodated in a tape-like holder for component supply in an aligned state to form a so-called taping component or in a tray or cassette for component supply in an aligned state. Is done.

However, even if the components to be accommodated have different orientations, even if the automatic component mounting machine and the automatic component mounting machine can automatically cope with this, the orientation of the supplied components can be determined and the components can be detected based on this determination. Orientation correction, or treatment of parts that cannot be rectified or are treated as defective without being rectified,
Since work such as resupply of proper parts is required, work efficiency is greatly affected.

Therefore, the index table 4 automatically determines the orientation and the like of the component 1 to be supplied to the next process, and eliminates the defective component 1 in advance. The rejected parts are not defective in quality per se even if the supply direction is bad, and the rejected parts are carried again to the aligning and conveying means A and reused.

[0007]

However, the reuse of the parts requires a special container or work for collecting the excluded parts and carrying them to the aligning and conveying means A for loading. Therefore, the apparatus and the work are complicated and the cost is increased. Further, there are disadvantages that the expenses of the parts in the hopper are high and the parts need to be replenished frequently.

The component feeder of the present invention aims to solve such a problem, and aligns and conveys the components to be eliminated due to the improper orientation in the stage of transferring to the next process without a special container or work. It is an object of the present invention to provide a component supply device that can be returned to the inside of the hopper of the means and that has a simple structure and operation.

[0009]

In order to achieve the above-mentioned object, the component supplying apparatus of the present invention is arranged and conveyed by aligning and conveying the components in a hopper along a guide, and is conveyed by the aligning and conveying means. In a component supply device having a transfer means for sequentially transferring the received parts to the next process while sequentially receiving the parts to the part receiving part and sending the parts each time and supplying the parts to the next process, Detecting means for detecting the quality of the orientation of the component received by the component receiving part on the way of the transfer path from the component receiving position to the component supplying position, and the part for which the detection result by the detecting means is defective is discharged from the component receiving part. And a discharging means for sequentially providing the discharging means for discharging the components received in the component receiving portion into the hopper. It is an butterfly. In addition, the quality of the orientation of the component refers to whether or not the front and back of the component and the posture in the front, rear, left, and right directions are desired.

In the transfer means, it is preferable that the transfer path portion through which the parts are discharged by the discharge means is located above the opening area of the hopper.

[0011]

In the above-mentioned structure of the component supply apparatus of the present invention, the aligning and conveying means sends out the components in the hopper while aligning them in the guide, and at the same time the transferring means is guided by the aligning and conveying means from the hopper to the guide. While sequentially receiving the incoming parts to the parts receiving section, the parts after the reception are repeatedly transferred to the next process and sent out each time to be supplied to the next process. The detection means and the discharge means are located in the middle of the transfer path of each component that is sequentially and repeatedly transferred from the position where the component receiving portion of the transfer means receives the component to the position where the received component is supplied to the next process. The means detects whether the transferred parts are in the wrong direction, and the discharging means discharges the defective parts detected by the detecting means from the part receiving section.Therefore, supply only the correct direction to the next process. In particular, since the discharging means discharges the defective part from the transfer path into the hopper, it can be returned to the hopper without any special container or operation so that it can be reused. , Equipment and work are simplified. It also eliminates the need for frequent replenishment of parts in the hopper.

In the structure in which the transfer path of the transfer means for discharging the parts by the discharging means is located above the hopper, the discharging means discharges the parts into the hopper. Since it is carried out from the transfer path located above the opening area of the hopper, the simple operation of naturally dropping the parts received in the parts receiving part is sufficient, and the structure of the device is further simplified and The return efficiency of parts is high.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The component supply apparatus of the present invention will be specifically described below with reference to one embodiment.

1 and 2 show a component supply apparatus as an embodiment of the present invention. As shown in FIGS. 1 and 2, the apparatus of the present embodiment guides and aligns the parts 1 in the bowl-shaped hopper 10 by the guides 2 along the peripheral wall 10a of the bowl-shaped hopper 10 while aligning them from the hopper 10. While sequentially receiving the aligning and conveying means A for sending out and the parts 1 conveyed by the aligning and conveying means A, the parts 1 after the receipt are transferred to a next step C at a predetermined position and sent out. And a transfer means B for supplying.

The aligning and conveying means A may be of any type as long as it can convey the components 1 in the hopper 10 in an aligned state by directing the guides 2 toward the tip of the guide 2. Vibration of hopper 10 and hopper 10
It is possible to employ various types such as a type that utilizes the rotation of a rotating disk (not shown) that is inclinedly arranged inside, or a type that feeds it to the guide 2 by other means. Since these are publicly known, illustration and description are omitted. The guide 2 may be of any type as long as it can guide the components 1 in an aligned state, and various types are adopted according to the alignment method and the transportation method of the components 1 or the shape and size of the components 1. be able to.

In the present embodiment, the transfer means B employs an index table 4 having a large number of recessed component receiving portions 3 each having a component receiving opening 3a on its outer peripheral surface as shown in FIG. This rotates intermittently to circulate and move each component receiving portion 3 intermittently, so that each time the component receiving portion 3 faces the tip of the guide 2, the component 1 sent toward the tip of the guide 3 is fed into the component receiving port 3a. It is possible to repeatedly carry out the process of receiving the parts 1 through the above, sequentially transferring the received parts 1 to the side of the next step C, and feeding and supplying the parts 1 when facing the next step C. An air passage 28 is provided in each of the component receiving portions 3, and the received component 1 is supplied to the air passage 2
As shown in FIG. 2A on the back wall of the component receiving portion 3 by suction through
Part 1 by adsorbing as shown by the virtual line
Is surely received and can be positioned at a predetermined position.

However, the component receiving portion 3 has a concave shape in which the component 1 is fed sideways from the tip of the guide 2 as described above, and the component 1 fed to the tip of the guide 2 is a suction nozzle or the like. Picked up and transferred, and next step C
The component 1 may be transferred by using various transfer means such as a suction nozzle that is picked up by a suction nozzle or the like to be supplied to the next step C when facing. Further, a transfer system in which the parts 1 are repeatedly transferred from the aligning and conveying means A to the next step C in the parts receiving section 3
In addition to the circulating movement method by turning using the rotating index table 4 or the like, the belt may be circulated and moved by a free path by moving a belt, a chain, a rope or the like. Depending on the case, it is also possible to adopt a structure in which the component receiving portion 3 is reciprocally moved or circulated in a linear direction to transfer and supply the component 1.

The next step C is not particularly limited as long as it sequentially receives the components 1 received by the component receiving portion 3 of the transfer means B and transported to a predetermined position and handles them in various ways. However, it is more effective to use a process of forming a taping component or the like for automatically supplying the electronic component to the electronic component mounting machine or the automatic mounting machine.

The index table 4 of this embodiment is intermittently driven by the drive motor 18 so that the component receiving portion 3 of the index table 4 is stopped for a certain period of time each time it faces the tip of the guide 2 or the next step C, and the index table 4 is moved from the guide 2 to the index table 4. The component 1 is received in the component receiving portion 3 and the component receiving portion 3 is surely supplied to the next step C. Also, 1 on the index table 4
Compared to the case where one component receiving portion 3 faces the tip of the guide 2 and at the same time, one component receiving portion 3 faces the next process C, and these facings are performed at different times. However, the number of required stoppages of the index table 4 is halved, which is preferable.

By the way, when the parts 1 conveyed toward the tip of the guide 2 by the aligning and conveying means A are cubic or rectangular parallelepiped, even if they are aligned along the guide 2, The orientation and the front and back may not be uniform. To deal with this, index table 4
The image pickup means 27 for detecting the orientation of the component 1 received in the component receiving portion 3 is arranged on the transfer route of the component 1 by the image pickup means 27, and the image pickup data by the image pickup means 27 is subjected to data processing to obtain the component 1 Of the air passage 2 that is connected to the component receiving portion 3 by detecting the direction of the
The air is blown out from 8 to eliminate it as shown in FIG. 2 (b). Therefore, in the next step C, it is possible to supply only the component 1 having a fixed orientation.

Suction of the air through the air passage 28,
The blowing of the air described here can be achieved by switching connection between the air suction path and the air supply path of the air passage 28 according to the rotation position of the index table 4, and in some cases, another air passage is individually provided. Can also be provided. Then, the positioning by suction through the air passage 28 is maintained from the time when the component receiving portion 3 receives the component 1 until the detection by the image pickup means 27 for detecting the orientation of the received component 1. To As a result, it is possible to avoid an error in the detection of the orientation due to the displacement of the component 1.

The component 1 from the component receiving portion 3 to the next step C
2 can also be supplied by blowing air from the air passage 28 of the component receiving portion 3 as shown in FIG. 2 (c).

The discharge position of the component 1 is shown in FIGS. 1 and 2 (b).
As shown in FIG. 5, the position is set at a position shifted from the defect detection position by the image pickup means 27 by one pitch in the arrangement of the component receiving portions 3 in the component transfer direction. However, the determination position and the discharge position may be in the middle of the transfer path from the alignment receiving means 3 to the transfer of the parts 1 from the aligning and conveying means A to the next step C, and are limited to the positional relationship shown in this embodiment. It is not something that will be done.

However, the discharge of the component 1 is as shown in FIGS.
As indicated by the broken line arrow b in (b) of FIG.

As a result, it is possible to return the component 1 to be discharged only in the bad orientation to the inside of the hopper 10 without any special container or operation so as to be reused.

Moreover, in the present embodiment, the transfer path portion 29 in which the parts are discharged by the air blowing from the air passage 28 as the parts discharging means of the transferring means B is located above the opening area of the hopper 10. . For this reason, the component 1 having the bad supply direction being transported by the transport means B is discharged from the transport path portion 29 located above the opening area of the hopper 10 of the transport means B, so that the component 1 is discharged into the hopper. A simple operation of naturally dropping the component 1 received by the receiving portion 3 is sufficient, the structure of the device is further simplified, and the efficiency of returning the component into the hopper is increased.

The component discharging means may be one that is pushed out by a pusher or another suitable one in addition to blowing air from the air passage 28 or the like. Depending on the case, a transfer means such as a suction nozzle can be used.

[0028]

According to the present invention, the aligning and conveying means sends out the parts in the hopper while aligning the parts in the hopper along with the guide, and at the same time, the conveying means guides and sends out the guides from the hopper by the aligning and conveying means. While the parts are sequentially received by the parts receiving portion, the parts after the reception are repeatedly transferred to the next process, and are sent out each time to be supplied to the next process. From the position where the parts receiving part of the transfer means receives the parts,
The detection means and the discharge means are located in the middle of the transfer path of each part that sequentially and repeatedly transfers the received parts to the position where they are supplied to the next process, and the detection means detects whether the transferred parts are in the wrong orientation. However, since the discharging means discharges the defective component detected by the detecting means from the component receiving portion, it is possible to supply only the component in the normal direction to the next process. Since the discharge is directed from the transfer path into the hopper, it can be returned to the hopper and reused without any special container or operation, which simplifies the apparatus and operation. It also eliminates the need for frequent replenishment of parts in the hopper.

In the structure in which the transfer path of the transfer means for discharging the parts by the discharging means is located above the hopper, the discharging means discharges the parts having a bad supply direction into the hopper. Since it is carried out from the transfer path located above the opening area of the hopper, the simple operation of naturally dropping the parts received in the parts receiving part is sufficient, and the structure of the device is further simplified and The return efficiency of parts is high.
