Description

[Detailed description of the invention] The present invention relates to an automatic supply device for electrical components.

For electrical components such as capacitors, the electrical characteristics of all electrical components are measured after manufacturing.
In such cases, it is desirable to align the individual parts one after another and automatically feed them into the measuring instrument.

The present invention provides an automatic feeding device for this purpose, and the present invention will be explained in detail in the following examples.

In Fig. 1, many trough-like magazines 2, 2, ... are fixed side by side at regular intervals on a conveyor 1, and each magazine stores an array body 3 (for convenience, three magazines are shown in the figure). (Only one magazine is shown, and only one of them houses the array body 3).

As shown in FIG. 3, the arrayed body 3 includes a plurality of polyester film capacitors 5 as electrical components arranged along a plate-like base 4 made of cardboard or iron plate.
The leads of each capacitor are temporarily fixed to the surface of the base 4 using an adhesive tape 6 as a tape material.

A ratchet wheel 8 is attached to the drive shaft 7 of the conveyor 1, and when the rotation of the first motor 9 is transmitted to the eccentric wheel 11 via the first electromagnetic clutch 10,
A feed pawl 12 connected to the eccentric wheel swings to cause the ratchet wheel 8 to rotate step by step. Therefore, these conveyor 1, drive shaft 7, ratchet wheel 8, first motor 9, first electromagnetic clutch 10, eccentric wheel 1
1. A feeding means is constituted by the feeding claw 12, and as the conveyor 1 moves, the aligned bodies 3 stored in the magazine 2 sequentially reach a predetermined insertion position. Now, if we assume that the magazine position in which the alignment body 3 is inserted is the above-mentioned insertion position as shown in the figure, when the alignment body reaches the above-mentioned insertion position, the eccentric wheel 11
The feed arm 15 rotates around the fulcrum 16 due to the movement of the cam 13 and the cam follower 14, which are interlocked with the alignment body 3, with the tip of the rotation being at the insertion position.
and pushes out the aligned body from the magazine 2.
In this way, the alignment body 3 pushed out by the pushing means consisting of the feed claw 12, the eccentric wheel 11, the cam 13, the cam follower 14, and the feed arm 15 is transferred to the first pressing roller 17 as a transfer means located in front of the alignment body 3.
and the first feed roller 18.

The power transmission wheel 19 has a flange 21 fixed to the first feed roller 18 by the pressing force of a spring 20.
The friction force causes the first
The rotation of the motor 9 is transmitted to the first feed roller 18. Therefore, the aligned body 3 is further fed by the first feed roller 18 and inserted into the insertion path 22.

As shown in FIG.
It has a groove 23 through which only one sheet can pass. Therefore,
If the aligned body 3 that is sent through the insertion path 22 by the first feed roller 18 has already entered the aligned body in front of the insertion path 22, it will collide with this, and at this time, it will come into contact with the aligned body 3 between the flange 21 and the power transmission wheel 19. This causes slippage and the subsequent feed of the aligned body is stopped. Further, a long hole 24 is provided near the entrance of the insertion path 22 and is perpendicular to the groove 23, and the actuator 26 of the first switch 25 faces the inside of the long hole 24. At position 24, the actuator 26 is pushed out of the elongated hole 24 by the alignment body, and the first switch 25 is turned off. Furthermore, a long hole similar to the hole 24 is provided near the exit of the insertion path 22, and a second pressure roller 27 and a second feed roller 28 face each other and face this hole. The second feed roller 28 receives the rotational force of the first motor 9 via the second electromagnetic clutch 29, so that the alignment body 3 is transferred in the alignment direction within the insertion path 22 after the first feed roller 18. The second feed roller 28 then takes over. As a result of this transfer, the aligned body 3 is finally discharged from the exit of the insertion path 22, but it passes through an extraction position on the way.

At the extraction position, an actuator of the second switch 30 and a preliminary chuck 31 that moves up and down as preliminary extraction means are arranged. The second switch 30 is turned on when the lead of the capacitor 5 is pushed away by the actuator of the second switch 30 when the capacitor 5 is in the above-mentioned extraction position. The spare chuck 31 has a pair of claws 32a and 32b to clamp the leads of the capacitor 5 in the above-mentioned extraction position, and a support shaft 33 of each claw
a, 33b are rotatably abutted and supported by a lever 34 at their lower ends, and support shafts 33a, 33b
Gears 35a and 35b inserted between the two mesh with each other.

When the rotation of the first motor 9 is transmitted to the chuck opening/closing cam 37 via the third electromagnetic clutch 36, the cam follower 38 in sliding contact with the cam and the crack 39 interlocked therewith drive the gear 35a, so that the chuck 31 is closed. Each rotation of the opening/closing cam 37 first closes and then opens. The chuck up/down cam 40 rotates together with the chuck opening/closing cam 37 to move up and down the lever 34 connected to the tip of the cam follower 41 that is in sliding contact with the chuck up/down cam 40, thereby moving the support shafts 33a, 33b up and down.

That is, the chuck 31 rises in its closed position and then lowers in its open position.

Thus, the base body 4 of the aligned body is pressed against the second pressure roller 27.
Since the capacitor 5 is held in pressure contact with the second feed roller 28, the capacitor 5 in the above-mentioned extraction position is almost, but not completely, pulled out from the adhesive tape 6 by the closing and rising of the chuck 31.

As shown in FIG. 2, a main chuck 50 is arranged above the preliminary chuck 31 as a main extracting means. It is completely pulled out by 50.

Referring to FIG. 2 below, distribution arms 51 arranged at 90 degrees, each having the main chuck 50 attached to its tip, are rotationally driven by a second motor 54 via a fourth electromagnetic clutch 52 and a Geneva mechanism 53. This constitutes a rotary transfer means.

The Geneva mechanism 53 consists of a drive board 55 on the motor side and a slit board 56 on the distribution arm side.
A drive pin 57 is installed in the slit plate 56.
is provided with a slit 58 arranged 45 degrees offset from the distribution arm 51, and the drive pin 57 enters the slit 58 during its rotation, and engages with the slit to rotate the slit plate 56 by 90 degrees. It separates from the rear slit 58. Therefore, the distribution arm 51 stops at four station positions and moves intermittently between them. A third switch 60 interlocked with the cam 59 detects the stopped state of the distribution arm 51. Also, the reserve chuck 31 is located at one of the station positions.

Hereinafter, such a position will be referred to as a first station position, and positions sequentially spaced apart by 90 degrees from it will be referred to as second to fourth station positions.

A slide guide 6 is provided at the tip of each distribution arm 51.
1 is fixedly installed, and the slide rod 6 is
2 is guided so that it can be raised and lowered. First and second air cylinders 63 and 64 are arranged above the first station position and a third station position 180 degrees away from the first station position, and a U-shaped engagement body 65 at the tip of the piston hangs down from each cylinder. is engaged with the slide rod 62 in the first and third station positions at its engagement pin 66, so that in the first and third station positions, the slide rod 62 is in the first and third station positions.
It is driven up and down by the second cylinders 63 and 64.

The main chuck 50 mentioned above is attached to the lower end of the slide rod 62. That is, as shown in FIG. 5, a slide body 71 screwed to the upper part of the rear surface of a chuck board 70 is inserted into an elongated hole 72 provided below the slide rod 62, and a spring 7 disposed within the elongated hole.
It is pressed downward by 3. Therefore, the spring 73
This means that the chuck board 70 is supported so as to be able to move up and down with respect to the slide rod 62, although there is a drag force due to this. Note that the slide guide 61 is omitted in FIGS. 5B, C, and D.

On the other hand, a holding lever 75 is mounted on the back surface of the chuck board 70, and is rotatably supported around a fulcrum 74 and biased counterclockwise by a spring 76. The chuck board 70 is engaged with a notch provided at the lower end of the chuck board 70, and unless such engagement is released, the chuck board 70
cannot move upward relative to the slide rod 62. The lower end of the holding lever 75 protrudes slightly from the lower end of the chuck board 70 in the above-mentioned engaged state, and by pushing up the lower end of the holding lever, the holding lever can be rotated clockwise to release the above-mentioned engagement. .

A long hole 77 is formed along the lower center of the chuck board 70.
An operating pin 78 is inserted into the elongated hole so as to be movable up and down along the elongated hole, and the pin head 79 and pin foot 80 of the operating pin 78 protrude from the back and front surfaces of the chuck board 70, respectively. To position.

A pair of chuck claws 81a and 81b are supported on the surface of the chuck base plate 70 so as to be rotatable about fulcrums 82a and 82b, respectively. Chuck claw 81
Interlocking levers 84a, 84a and 83b are interlocked between the intermediate supports 83a and 83b of a and 81b and the pin leg 80 of the operation pin 78,
84b is passed, therefore the chuck claw 81
a and 81b are closed when the operation pin 78 is at the upper end position of the elongated hole 77, and opened when it is at the lower end position. The opening/closing state is achieved by the intermediate fulcrums 83a, 83 of the chuck claws.
It is held by a spring 85 installed between b.

Rubber pieces 86a and 86b are attached to the ends of the chuck claws 81a and 81b so as to face each other, so that when the chuck claws are in the closed state, the winding portion of the capacitor 5 can be clamped without being damaged.

1 rotatably provided on the slide guide 61
The pair of clamping levers 87a, 87b are springs 88a, 8
Rollers 89a and 89b attached to the tips of the rollers 89a and 89b engage with notches 90a and 90b on both sides of the upper part of the chuck base plate 70 to hold the slide rod 62 at a specific height. This specific height is the standby state of the air cylinders 63 and 64,
In other words, this is the height of the U-shaped engaging body 65 when the piston is stopped at the uppermost position, and the engaging pin 66 of the slide rod 62 is raised by the rotation of the distribution arm 51.
When the main chuck 50 is separated from the U-shaped engaging body 65, the clamping levers 87a and 87b prevent the sliding rod 62 from lowering below the specified height due to the weight of the main chuck 50.

The chuck pawls 81a, 81b of the main chuck 50 are closed at the first station position and opened at the third station position, so that the distribution arm 51 moves from the first station position to the third station position via the second station position. It is in the closed state during the entire journey, and is in the open state during the journey from the third station position to the first station position via the fourth station position.

chuck claw 81a at the first station position;
The closing operation of 81b is as follows. At the first station position, the chuck pawl is initially in an open state as shown in FIG. 5A, and then the first air cylinder 63
When the slide lever 62 is moved down, the chuck board 70 is also moved away from the clamping levers 87a and 87b and lowered. During its descent, the operating pin 78
The pin head 79 hits the first block 100 (FIG. 2) fixed on the downward path of the pin head, and therefore, as the slide rod 62 descends thereafter, the operating pin 78 moves against the chuck board 70. The chuck claws 81a and 81b are relatively raised and closed. In this closed position, the winding portion of the capacitor 5 which has been preliminarily pulled out from the arrangement body by the preliminary chuck 31 is located, so that the chuck pawls 81a, 81b can clamp this winding portion. The first air cylinder 63 then pulls up the slide rod 62 to its original position, that is, to the specified height, and the chuck board 70 is again held by the holding levers 87a and 87b.
At this time, the chuck claws 81a and 81b remain closed, so it is clear that the capacitor 5 has been completely pulled out from the array body 3.

chuck claw 81a at the third station position;
The opening operation of 81b is as follows. At the third station position, the chuck pawl is initially in a closed state as shown in FIG. 5B, and then the second air cylinder 64
When the slide lever 62 is lowered by operation, the chuck substrate 70 is also moved away from the clamping levers 87a and 87b and lowered. During its descent, the holding lever 7
A second block 101 (FIG. 2) fixedly installed on the lower end of 5 and the lower end of the chuck board 70 (FIG. 2),
First, the lower end of the holding lever 75 hits, and as a result, as the sliding rod 62 subsequently descends slightly, the engagement between the tip of the holding lever 75 and the lower end of the sliding rod 62 is disengaged. Then, the lower end of the chuck board 70 hits the second block 101, and as a result, as the slide rod 62 is lowered thereafter, the slide rod 62
The lower end of the pin comes into contact with the pin head 79 to lower the operation pin 78, which causes the chuck claws 81a, 81b to
opens. At this time, the capacitor 5 held by the chuck claws 81a and 81b falls with its leads facing down. The second air cylinder 64 then pulls up the slide rod 62 to its original position.
The chuck board 70 is again held by the clamping levers 87a, 87.
b, and the holding lever 75 and the slide rod 62 are engaged with each other.

Referring again to FIG. 2, below the third station position are a plurality of measurement terminal sockets 1 lined up in a row.
02, 102, . . . are driven by separate motors and run continuously, and the capacitor falls into the socket 102 which reaches the drop point of the capacitor. That is, the socket 102 has a pair of socket holes 10.
3a, 103b, and socket holes 103a, 1
Each lead of the capacitor is inserted into each of 03b. An automatic measuring device (not shown) is placed at the destination of the measuring terminal sockets 102, 102, .
The electrical characteristics are measured via 103b and the capacitors are sorted according to their capacitance classification, for example.

A fourth switch 104 detects by means of a protrusion 105 provided on each socket 102 that the socket 102 has reached the drop point of the capacitor, and determines the timing for dropping the capacitor.

Below the second station position are a pair of blades 106a, 10 that open left and right as lead wire expansion means.
6b is arranged, and the blades slightly spread outward the two leads of the capacitor held by the main chuck 50, making it easier to drop and insert the capacitor into the socket 102 at the subsequent third station position. . That is, the blades 106a and 106b are initially closed within the opening and closing planes of the chuck claws 81a and 81b, and therefore, when the main chuck 50 reaches the second station position, the chuck claws 81
The blade 106 in the closed state is placed between the two leads of the capacitor that are lined up perpendicularly to the open/close planes a and 81b.
Since the blades a and 106b are inserted, the two leads are expanded by opening these blades. The opening/closing operation of the blades is performed by a cam 107 that receives rotation of the fourth electromagnetic clutch 52 and a cam follower 108 that is in sliding contact with the cam.
and a pair of gears 1 rotated by the cam follower.
09a, 109b.

Next, the cooperative operation of each part of the above device will be explained.

If the alignment member 3 is not present near the entrance of the insertion path 22 in FIG. 1, the first switch 25 is turned on and the first electromagnetic clutch 10 is put into operation.
As a result, the arrayed bodies 3 are fed on the conveyor 1, and when the arrayed bodies 3 reach the insertion position, the feed arm 15 works and the arrayed bodies 3 are moved to the first feed roller 18.
Thereafter, it is inserted into the insertion path 22 by the first feed roller 18. After such insertion, the first electromagnetic clutch 10 is kept inactive as the array 3 turns off the first switch 25, and the feeding of the array 3 on the conveyor 1 is stopped.

The alignment body 3 moves inside the insertion path 22 by the second feed roller 28
The condenser 5 of the array is further transported by
When it reaches the above-mentioned extraction position, the second switch 3
0 is turned on, the second electromagnetic clutch 29 becomes inactive, and the third electromagnetic clutch 36 becomes active. As a result, the second feed roller 28 is stopped and the capacitor 5 is stopped at the extraction position, while the reserve chuck 31 is activated and the capacitor array 3 is stopped.
Preliminary samples are taken from. Note that the second switch 30 is turned on because the capacitor is still in the extraction position.

When the second switch 30 is in the ON state and the third switch 60 is ON, that is, each distribution arm 51 is stopped at each station position, the first air cylinder 63 causes its piston to move downward and upward. The capacitor is then completely extracted by the main chuck 50. On the other hand, when the fourth switch 104 detects that the socket 102 has reached the capacitor drop point, the second air cylinder 64 causes its piston to move downward and upward, so that the capacitor separates from the main chuck 50 and falls.

After the above-mentioned operations of the first and second air cylinders 63, 64 are completed, the fourth electromagnetic clutch 52 is activated, the distribution arm 51 is rotated 90 degrees, the third switch 60 is turned off, and the distribution arm 51 is at the station position. When it reaches the third switch 60
is turned on again. Based on this change in state of the third switch 60 from off to on, the fourth electromagnetic clutch 52 becomes inoperative.

Also, after the capacitor is completely pulled out by the main chuck 50, the second switch 30 is turned off, so that the second and third electromagnetic clutches 29 and 36 are in the operative and non-operative states, respectively, and the second feed roller 28 is again turned off. is driven, and the above process is therefore repeated.

As is clear from the above explanation, according to the present invention, by preparing a large number of arrayed bodies in which a pair of lead wires are temporarily fixed and aligned on a plate-shaped base by fixing them with a tape material, the arrayed bodies can be Since the electrical components can be sequentially transferred along the insertion path, it becomes easy to extract the electrical components one by one from the arrayed body sent in this way and supply them to the measuring instrument. Further, the insertion path for this purpose has a groove in the transfer direction that can accommodate only one substrate, and since the drive of the feed roller is controlled by the slip torque of frictional force, two or more aligned bodies can be inserted at the same time. It is possible to ensure a reliable supply without being fed, and there is no need to check the feeding status with a sensor or the like, and continuous feeding is possible.

In addition, since the electrical components of the arrayed body that have reached a predetermined extraction position in the insertion path are preliminarily extracted by the preliminary chuck by the transfer means consisting of the first feed roller and the first pressure roller, the main extraction Using the main chuck as a means, it is possible to reliably pull out the electrical components completely.

Furthermore, the pair of lead wires of the electrical component is expanded by the pair of blades serving as the lead wire expansion means during the rotational transfer by the distribution arm serving as the rotation transfer means, so that the measurement by the measuring device is improved. Lead wires of electrical components can be suitably inserted into the terminals.
