JPS5811411A - Equipment for truing up minute parts - Google Patents

Abstract

PURPOSE:To efficiently true up minute parts which have a directional characteristic, by supplying the parts to a holding hole when a turntable is in one rotational position and by using a detector to find out the direction of the parts when the table is in another rotational position and by taking out the parts depedning on their direction when the table in still another rotational position. CONSTITUTION:At a primary true-up section 8, the postures of clampers are restricted to two kinds 6a, 6b. The clampers are conveyed by a straight movement feeder 9 and surely held one by one in the holding holes 20 of a turntable 11 by a suction means 10. The clampers are then moved by the rotation of the turntable 11. The difference between the postures 6a, 6b of the clampers is found out by the detector 12. A controller 13 sets the angle of rotation at 180 deg. or 90 deg. on the basis of the signal of the detector 12 to oppose the clampers to takeout sections 14a, 14b corresponding to the postures 6a, 6b, to push the clampers out into true-up sections 15a, 15b. After that, the true-up sections 15a, 15b are removed. Two rows of the clampers trued up in the same direction are thus efficiently provided.

Description

[Detailed Description of the Invention] The present invention relates to a micro parts alignment device that aligns the directions of micro parts that have directionality, and its purpose is that dimensional differences due to directionality are small and it is difficult to sort out directionality. The aim is to effectively align minute parts with different shapes.

The first device to align conventionally oriented parts
As shown in FIGS. (7) and (A), there was a system in which parts 2 fed by a parts feeder 1 or the like were sorted and aligned using a gate 3 provided in a prominent manner. This gate part 3
As shown in FIG. 1A, a gate plate 3' having a predetermined directionality is provided, and alignment is performed by selecting only parts in a direction that can pass through this gate plate 3'.

At this time, if the part 2 is minute and the dimensional difference due to directionality is small, even a slight break will have a large effect, so it will easily get clogged in the gate part 3, and even when it is in the correct direction, it may get caught and removed. Yes, reliability, availability,
There was a problem with alignment efficiency.

The present invention is a micro parts aligning device that eliminates the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings. Consider the clamper e that clamps the end of the magnetic tape 6 to the hub 4 of the micro-force set tape as shown in Figures (G) and (B). Since there is not much difference, it is difficult to sort using the conventional gate plate 31.

FIG. 3 is a perspective view of this embodiment, and FIG. 4 is a sectional view of the main part from direction P in the figure.

The clampers 6 randomly supplied to the parts feeder 7 have four types of postures ea and eb shown in FIG.

It reaches the primary alignment part 8 in either ea or ad posture,
Due to the dimensional condition of A<C shown in FIG. 2 (7), the posture ec and 6d are removed here.

The clampers in postures ea and sb pass through the linear feeder 9 and are sucked and held by the rotary table 11 in the suction section 10, and when the rotary table has rotated 90 times, the detection section 12
Which of the two directions is detected is detected. An output signal from the control section 13 which receives this detection output as an input causes the clamper to move to the extraction section 14a.

At 14bVc, they are each taken out from the rotary table 11 and aligned in alignment sections 15a and 16bK.

Further details of each part will be explained below.

FIG. 6 is a perspective view of the primary alignment section 8, and FIG. 6 is a sectional view thereof. 7 is a parts feeder through which the clamp 6 is conveyed, 2
4 is a motor for driving this primary alignment section 8, and 16 is a drive pulley provided on the shaft of the motor 24. 17 is a belt that transmits driving force to the driven side boob IJ 18, and 19 is a rail provided continuously to the parts feeder 7. The driven side boob IJ18 is positioned above the rail 19. The pulley 18 has a shape in which a regular pulley and a square plate having one side slightly larger than the diameter of this pulley are fixed together, and the lower surface of this square plate-shaped part and the front = e A predetermined distance K is provided between the rail 19 and the conveyance surface.

Here, the clamper 6 conveyed on the rail 19 has four postures (7) to (9) in FIG. 4. The lengths of each part of the clamper 6 are set as shown in FIG. For example, in postures ea and eb in FIG. If the distance K from the surface is 〈K〉0, the posture 6a, e
Only the clamper b will be transported on the rail.

Therefore, in this primary alignment section 8, the clampers 6 in various postures, which have been conveyed by the parts feeder 7, are fed into the rail 19 as they are. On the other hand, the rotation of the motor 24 is transmitted to a pulley 18 by a pulley 16 and a belt 17, and the lower surface of this pulley rotates while maintaining a distance K from the conveying surface of the rail 19 as described above. Therefore the height C
The clamper in the posture ec, 6d, which is being conveyed on the rail, contacts the lower end of the pulley 18, and slides down from the rail 19, which has one side open and forms a slope. The clamper removed and dropped from the pulley 1BK is automatically collected by the parts feeder 7 and conveyed again. On the other hand, the clamper in the posture ea+eb, which has been conveyed on the rail by a person, passes through the col rail 19 and is sent to the next device. Also, if the clamper in postures 6c and 6d comes into contact with the pulley 18 and remains on the rail in postures 6a and eb, it is conveyed and sent as is, that is, the posture has been corrected. FIG. 7 shows a perspective view of the suction unit 10 and the rotary table 11, and FIG. 8 shows a sectional view of the main parts thereof.

The clampers 6 aligned in two directions (postures 6a, 6b) in the primary alignment section 8 are conveyed to the surface of the rotary table 11 by the linear feeder 9. The rotary table 11 is provided with holding holes 20 every 90 degrees, which communicate the front and back surfaces. A suction section 10 is provided on the back surface of this rotary table 11,
The holding hole 2o is located on the extension of the central axis of the linear feeder 9, and the suction port 21 of the suction unit 10 is connected to the holding hole 20.
is aligned and opened. Therefore, the clamper 6 that has been conveyed to the surface of the rotary table 11 is moved to the holding hole 2 of the rotary table 11 by the conveying action using the vibration of the linear feeder 9 and the suction force of the air from the suction port 21.
After that, the rotary table 11 rotates 90 times around its axis 25 to transfer the clamper housed in the holding hole 20 to the detection section 12. Note that at this time, the next clamper is held by suction in the next holding hole at a position 90 different from the previous one.

FIG. 9 shows a perspective view of the detection unit 12. Figure 10 (g),
(A) is a front view for explaining the detection state by the detection piece 23.

In this case, a sloped portion 26 is provided at one corner of the holding hole 2o, and the tip of the detection piece 23 that contacts the clamper 6 is shaped within a horizontal plane. 22 is holding hole 2
This is a reference sleeve provided at the tip of the cylinder that rises in synchronization when the point o reaches a predetermined position.The detection piece 23 is held in this sleeve 22 and moves up and down independently.

Note that the reference sleeve 22 is raised and the rotary table 11
The detection piece 23 enters into a hole 27 provided in communication with the holding hole 20 from this circumferential end.

Fig. 10 (7) shows the case where the clamper is held in the holding hole 20 in the position 6a in Fig. 7, and Fig. 10 (a) shows the case where the clamper is held in the position 6b in Fig. 7, and this holding hole is held on the rotary table. The figure shows a state in which the sensor has reached the position of the detection unit 12 due to the rotation of the sensor.

With respect to the clamper held in posture 6a or 6b, when the reference sleeve 22 at the tip of the cylinder in the detection unit 12 rises and its upper surface contacts the circumferential end of the rotary table 11, the detection piece 23 in the reference sleeve 22 It rises to fit into the hole 27 of the rotary table. At this time, the clamper 6 in the holding hole 2o is pushed up by the detection piece 23, but due to the difference in shape and size due to the slope portion 26 and the postures 6M and 6bK, the distance from the upper surface of the reference sleeve 22 to the upper end of the detection piece 23 becomes H+ and H2. It makes a difference. (Here Ih,
>H2) Based on this difference, the attitude (directivity) of the clamper 6 in the holding hole 2o is detected, so the detection unit 12 sends a signal regarding this attitude to the control unit 1'3K as a detection output8. In this case, the shapes of the reference slip and the detection piece must be determined by minute parts. Also, the attitude (here, ea, eb) with respect to the clamper 6 is
It suffices if it can distinguish between
FIGS. 11(a) and 11(a) show other embodiments corresponding to FIGS. 10(7) and (a). It moves up and down 111 degrees. And Figure 11 (branch), (a)
As shown in FIG. 2, the configuration is such that the distance from the upper surface of the reference sleeve 22' to the upper end of the detection piece 23' varies (H1' (H2)) depending on the posture of the clamper when the lift is stopped.

Next, when the detection unit 12 detects the direction of the clamper, the control unit 13 causes the rotary table 11 to be set to 18g or 9g.
Rotated to 0. That is, for the clamper in the posture 6a, the holding hole 2o is 18
A control signal is issued to rotate the clamper 0 times, and a control signal is issued to cause the clamper in the posture 6b to rotate 90 degrees so that its holding hole faces the take-out portion 14b. Therefore, a single clamper with a single orientation (direction) is supplied to each take-out unit, and if the alignment units 16a, 15b are pushed out one by one, the alignment unit 15aK will be supplied with a clamper with a single orientation (direction). Crannos (with a posture 6b) are aligned and held in the portion 1sb.

FIG. 12 shows an operation flow chart of the device of this embodiment. According to the configuration of the above embodiment, the clamper posture is limited to two types, 6a or 6b, in the primary alignment section 8. It is possible to prevent clogging of the crane holes in the alignment section 8 and the linear feeder 9. Next, the clampers in the positions ea and eb fed by the linear feeder 9 can be reliably held one by one in the holding holes 20 of the rotary table 11 by the suction unit 10. Furthermore, the held clamper is moved away from the feed direction in a direction perpendicular to the feeding direction by the rotation of the rotary table 11 while being held, so efficiency is improved.
Next, the detecting section 12 detects the clamper's attitude 6a and the ebO difference, and the control section 13 receives this detection signal to set the rotation angle of the rotary table 11 to 180 or 9 g, and takes out the clamper corresponding to the attitude -68 or 6bK. Part 14a
, 14b [because they are made to face each other, it is easy to distinguish the remaining two types of posture and to separate them, and each take-out portion 14a.

The clampers pushed out by the alignment parts 16a and 15bK by the alignment part 14b should be surely aligned in only one direction. If the alignment parts 1sa and 1eib are removed, two clamper arrays aligned in exactly the same direction can be obtained, which is very efficient.

As described above, the micro parts alignment device of the present invention includes a supply section for micro parts having directionality, a rotary table that rotates intermittently, a holding hole for micro parts formed on the rotary table, and At the first rotation position of the take-out section and the rotary table, the minute parts are supplied from the supply section to the holding hole of the rotary table, and at the second rotation position, the minute parts are held in the holding hole by the detection section. The control unit detects the direction and controls the part to be taken out by the take-out unit according to the direction of the minute part detected at the third rotational position.

Therefore, according to the present invention, the directionality of the Nihartz can be accurately detected by the detection unit without clogging the supply unit of minute parts, and furthermore, the rotational position of the rotary table can be controlled using this detection output. This makes it possible to accurately and efficiently take out parts from the holding holes of the rotary table and align them.
