A cushion member 109 is attached to t'Hs. Next, when the plunger 106a of the air cylinder 106 is retracted, the arm 105 moves to the right and the crank lever 108
rotates in the direction of the hour hand. This rotation angle is set to 45°. In response to the rotation of the crank lever 108, the shaft 101 (according to the rail section 80aIt) is rotated 45 degrees to the SO8 position. In this state, air is injected from the rear of the IO from a nozzle (not shown), and the IC is 2 direction conversion ff1S21. By repeating such an operation, the direction of zero weight can be sequentially changed by 45 degrees within the vertical direction 1111 while being transported. Second Direction Changing Section FIG. 11 is a diagrammatic perspective view showing the overall configuration of the second direction changing section 27 that changes the conveyance direction of the workpiece 0 by 90 degrees in a horizontal plane, and FIG.

Suppose that A pulley 111 is fixed to the upper surface of the rotary table 11G via a shaft, and this pulley is connected to a pulley 118 via a timing belt 111. The diameter of this pulley 118 is made larger than the diameter of the pulley 111.A shaft 114 is fixed to the pulley 118, and an arm 1 is attached to this shaft.
One end of the first air cylinder 11 (S) is pivotally connected to one end of the first air cylinder 11 (S), and the tip of the plunger 116a of the first air cylinder 116 is pivotally connected to the other end of the first air cylinder 115 (7-A115). 17 are aligned and connected, and the tip of the plunger 117a of this second air cylinder is swingably supported via a bearing 118.These first and second air cylinders constitute the main body mechanism 7. t4>1[IA*B and 0 are n)l when the rotary table 11G is at the positions of -90°, 0°, and +90°, respectively.

50 directions can be rotated by 190'. In this case, the 1060 beam conveyed from the Q41 direction conversion section 26 is reversed by exactly 180'. Next, when the second air cylinder 117 is energized from the θ° position, the entire air cylinder 116t'3 Yohi 117 moves to the left as shown in Fig. 0, so the arm 115 moves in the counterclockwise direction. The shaft 114, second pulley 118, timing belt 118 and first
The rotary table 110 also rotates 90 degrees counterclockwise through the pulley 111.
'M moves and becomes +90' place ti. In this case, the workpiece 050 conveyed from the first direction conversion section 2B is sent to the rail 119 of the next stage correction section 2B with the direction unchanged. As mentioned above, in this example, the conveyance direction of workpiece 0 can be changed by 90 degrees in the horizontal plane, and at the same time, the direction of workpiece 10 can be reversed by one center on the foot, so compared to the case where these are provided separately, 4IjI construction is possible. can be made simple and compact, and the processing speed can be increased.As is clear from FIG. 18, two air cylinders 116
By selectively driving the air cylinders 11 and 117, eight positions iRk can be obtained.

By setting $146 like this, air cylinders 116 and 11? can be easily swung. As mentioned above, the turntable 110 rotates ±90° while holding l050, but in order to prevent the IC from protruding 1ξ from the turntable 11G during this rotation, a part of it is shown in FIG. A presser mechanism 811 shown in FIG. As shown in detail in FIG.

The tip of the lever 122 is bifurcated as clearly shown in FIG. 11, penetrates the pulley 111, protrudes into the rotating table 110, and is attached to the constriction of the shaft 1214 that presses the IO against the rail 110a from above. let A tension coil spring 125 is provided between one end of the lever 122 and the frame 11G, and biases the lever 122 in the direction of the hour hand as shown in FIG. After placing 1050 into the rotary table 110, the solenoid 121 is energized at a predetermined timing to release the plunger 1.
21a, the lever 122 is rotated counterclockwise against the force of the coil spring 125, the shaft 124 is pushed down, and the l050 is pressed against the rail 110a. Thereafter, plunger 118 or 117 is driven to rotate rotary table 110 90' in a predetermined direction.

Next, air is injected from the nozzle 120 shown in FIG. 14 to send the workpiece 050 to the rail 119 of the correction section. As shown in FIG.
It is made to act as a stopper when inserting the rotary table 110 into the rotary table 110, and also to absorb the shock of the @M east. When the turntable 110 rotates, this rubber ruler 1

Correction unit I-0 conveyed from the second direction changing unit 27 then enters the correction unit 2B, and the configuration and operation of this correction unit are the same as those described in the above-mentioned Japanese Patent Laid-Open No. 112187/1987. Since the parts and connections are the same, detailed explanation thereof will be omitted. Since the glue 61 section 28 of this example only corrects the posture of the IC bottle, the structure of the correction section is simple. That is, by forcibly forcing the IC bottles into a shallow inverted triangular groove, the mutual spacing between the bottles and the opening angle of the bottles are corrected to predetermined values. After the bottle has been corrected in the insertion part insertion head part correction part 2B, the workpiece 0 is then moved to the insertion part 12B.
However, as mentioned above, this push-in radius part δ grips the workpiece 0 and rotates between 0° and 90°, but in the conventional number position, the shock during this rotation is extremely This has the disadvantage of shortening the life of the insertion section and slowing down the operating speed. The insertion section of this example eliminates these drawbacks. Figures 15A to 15D show the configuration of the insertion head section 84, and an air cylinder is arranged inside the insertion head body 180. This causes the button 181 to move up and down. A pair of claws 182 a and 1811 b for gripping the workpiece 050 are provided at the lower end of the pushing head main body 180 . These claws are connected to the 16th claw in conjunction with the elevation of the bushing 181

The air cylinder 1 is installed approximately in the center of the lever 139 via a shaft.
This air cylinder 145, on which the 45 plungers 14B& are pivotally mounted, is fixed to the base 186. Therefore, by energizing the air cylinder 145, the coil spring 144a

The l060 gripped by a and 182b can be inserted into the printed binding board 88. On the other hand, when the air cylinder 150 is energized, the spacer 149 enters the descending passage of the shock absorber 147, so the descent of the matchmaker head body 180 is restricted.◇Such a configuration is useful when checking the operation of the automatic insertion device, etc. It is effective for FIGS. 16A and 16B show a mechanism for pushing the insertion head main body 180 90 degrees.

In this way, if the lever 15B is rotated 180 degrees using the lever 1a'', -158 and the cam lever 162, the rotation error of the blade at the end of this rotation will be almost zero, so the insertion head body At the end of the 90° co-movement of 180 degrees, the energy becomes zero, so there is almost no street attack, the life of each part is extended, and the speed of movement can be increased. In addition, since the coil spring 165 is arranged between the rods 154 and 156, it is possible to sufficiently absorb the vertical movement of the insertion head main amount 180, and the unreasonable force is applied to the lever 15.

Operation of insertion device No. 28 and 24@
This will be explained using the timing chart shown below. The operation of the loader 2 has already been explained, so it will be omitted, but the I obtained by detecting the passage of the load to the carrier case 29d.
The falling of the C passing signal is detected and the driving of the motor 29f of the next stage 10 transport stations 25 is started. The relationship between the operations of each element is indicated by arrows. In the IC transport section 2B, the movement of the chain 2190 is detected by a distance counter (not shown), and when a predetermined value is reached, the motor 29f is stopped, and the chain 2190 is moved.
Move 90 one pitch. The distance counter is cleared for each pitch. Next, the movement is moved to the l0t-first direction changing section 26, but this operation moves the rail section 80a from the 00 position to the 4
Start by rotating it to the 50 position. For this purpose, the air cylinder 106 is energized to rotate the rail 1aoa to the position 450. This is HoF, Inter 2 Buta 80
0, the air cylinder 90 is energized to push out the plunger 90a, the shutter 76 of the carrier case 29d is closed, and the IC is transported from the carrier case to the 10,000th rotation section. For this purpose, IC feed air is ejected from the nozzle. In response to the photoelectric detector 80d detecting that the workpiece 0 has been fed into the rail portion δOa, the air cylinder 106 is deenergized and the rail portion aOa is rotated to the 00 position. One operation of the first direction converting section 26 is completed at the time when the position of ψ is detected by the photo interface cover 800. Next, the IC is transported to the second direction changing section 27, and the timing of this transport is determined by the operating state of the second direction changing section. In the automatic insertion device described in the above-mentioned Japanese Patent Application Laid-Open No. 58-112889, a gate @ mechanism is provided between each operating section, and when the processing at that section is completed, the device is sent to the downstream gate mechanism and waits here. It is then conveyed to the next operating section at an appropriate timing. Although such a configuration can increase the overall processing speed, the provision of the gate mechanism has the disadvantage that the configuration becomes complicated and large, and the conveyance path becomes long. On the other hand, an unusual automatic insertion device does not include a gate mechanism and controls the transport of the IO according to the state of the next-stage operating section. Therefore, the structure is simple and compact, and the conveyance path is also shortened. For this purpose, a data file is created for each IO, and the IO is transported in accordance with the delivery of this file. For example, the above-described transfer of the IC to the transport section is started after the file has been moved to the transport section and the photoelectric detector GOD of the first direction conversion section 26 has detected the passage of the IC. In this way, by sequentially conveying work 0 together with the file without detecting the state of the operating section of the next stage, the gate mechanism can be omitted and the processing speed can be increased. Such a control method will be further explained later. The file is transferred from the first direction converter 26 to the second direction converter 27 using the photointerrupter aO of the m1 direction converter 26.
C detects the 00 position. In response to this, the cylinder 116 or 11 is driven to rotate the rotary table 1.
Move 10 from -900 or +900 to 00. When this movement is detected by the 00 detection photo-interrupter 81d, the nozzle provided in the first direction changing section 26 blows out the force f, and the IC is conveyed from the first direction changing section 26 to the second direction changing section 27. IC at this time
The movement of is detected by the yC electric detector 131g, and after detecting the passage, the air injection is stopped and the air cylinder 116 or 117 is driven to move the rotary table 110 to +900 or -9.
Rotate to the 00 position. At this time, the solenoid 121 is also energized, and the shaft 124 presses the l050 against the rail 110a. For example, when the photointerrupter 81e for +90'' detection detects that the rotary table 110 has been rotated +900 times, the solenoid 121 is deenergized.At this point, the file of the IO is delivered to the correction section 28.In the correction section 28, After driving the IC stopper a@82a, air is ejected from the nozzle of the second direction changing section 27 to send the IC to the correction section 28, where it is stopped.The passage of the IC at this time is detected by the photoelectric detector 81h. Then, the air injection is stopped, and at the same time, the IC correction mechanism 82b is driven to correct the IC pin.When a sensor (not shown) detects the completion of this correction operation, the operation of the correction mechanism a2b is stopped, and The operation of the stopper mechanism 82a is also stopped. Next, the data file of the IC is moved to the insertion section 28. In the insertion s28, as soon as the data file is received, air is injected from the nozzle provided in the correction section 28 to remove the data file from the correction section 28. Then, the IC is sent into the insertion section 28. At this time, the movement of the IC is detected by the photoelectric detector 820, and after a predetermined lapse of time, the air cylinder provided in the insertion head main body 130 is driven to release the claw 1a2a. 132b is moved to grip the IC.At the same time, the air cylinder 204 of the clinch section 86 is driven to raise the clinch table.The air cylinder 175 of the retract section 85 is also driven to retract the rail 170. When detected by the photo interrupter 88d, the air cylinder 145 of the insertion head section 84 is driven to lower the insertion head main body 180. ° This lowering of the insertion head main body is sequentially detected by the eight photo interrupters 870, 37d, and 876, and the lowermost In response to the photointerrupter 1l17eil generating a detection signal, the button 131 is further pushed out and the pin 1050 is inserted into the hole in the printed circuit board 88.At the same time, the air cylinder 185 of the clinch section 86 is driven to remove the printed circuit board. The tip of the pin 50a of l060 protruding downward from 88 is cut by the outer cutter and the inner cutter and bent inward. When the end of this operation is detected, the clinch g (air cylinder 185 of 16 is deenergized and the outer cutter and inner cutter After the blades are expanded, the air cylinder 204 is deenergized to lower the clinch head 39a, and the air cylinder 14 of the insertion head section 84 is
B is deenergized and the insertion head main body 180 is raised. When the clinch head descends, suction air is applied, resulting in zero work.
Aspirate the cut pieces from the bottle. Rough insertion head body 1
The air cylinder provided at 80 is deenergized to raise the button 181 and expand the claws 182a and 182b. When the arrival of the insertion head main body 18G to the raised position is detected by the photointerrupter 870, the tract section 85
The air cylinder 175 is driven to cause the rail 170 to protrude to the lower side of the insertion head main body 180. In the above explanation, the insertion head main body 180 and the clinch head 89a were not rotated, but when rotating by 90 degrees, after detecting that the rail 170 of the beam tract section 85 has retreated, the air cylinder 166tr is energized and inserted. After rotating the head body 180 by 90 degrees, it is lowered once. Further, the rotation of the clinch table is performed by energizing the motor 194 at the time when the data file of the work 0 is received. As described above, the ICs can be processed one after another and pushed into the pre-memorized predetermined positions on the printed circuit board 8δ in a predetermined direction. As mentioned above, to transport ICs between multiple drive units and to control the operation of each drive unit, a data file is created for each IC, and this data file is sequentially passed to the bone to control the operation of the drive units. At the same time, the movement of this data file is controlled according to the operating state of the next drive unit, but the movement of the data file from the first direction conversion unit 20 to the second direction conversion unit 27 is controlled by the next stage of correction. Optical core detector 8 of section 28
The 0 line is carried out in response to the IO passage detection signal from 1h, and the delivery from the second direction changing section 27 to the correction section 2B is carried out in response to the photoelectric detector 820 detecting the passage of the IO to the insertion section 28. . (Effect of the invention) According to the control method of the present invention described above, the G between the plurality of operating parts is
This enables efficient operation of each operating part without providing a gate mechanism.
Since it is possible to control ljlJ, the structure of the entire automatic insertion device can be made simple and compact, and as a result, the insertion speed and proper insertion rate can be improved.
