The upper screw shaft 199 has a handle 203 at the outer end, and is linked to the lower screw shaft 200 via a chain transmission system 204. If the handle 203 is rotated, the upper and lower screw shafts 199, 200 will move in the same direction. It is designed to rotate by the same amount.

Reference numeral 205 denotes a reflection type sensor for detecting the laminated substrate B, which is provided on one side of the lower frame 151, and a reflection plate 206 is provided on the other side of the lower frame 151 so as to face the reflection type sensor 205. . Reference numeral 207 denotes a pulse generator attached to the outer upper sliding plate 161, which is linked to the rack 209 via the pinion 208, and the rack 209 is fixed to the inner upper sliding plate 161.
Reference numeral 210 denotes a pulse generator for detecting the distance between the two inner guide plates 157, which is attached to one vertical frame 152 via a bracket and is interlockingly connected to the upper screw shaft 192 via gears 211,212.

Next, the operation from the loading of the printed circuit board A to the supply to the washing machine in each of the above devices will be described. First, the printed circuit board A is loaded on the loading conveyor 158 of each loading unit 156 of the loading device, and a large number of printed circuit boards A are vertically stacked.

At this time, the guide plates 157 on both sides of each loading section 156
The mutual interval is adjusted in advance according to the width of the printed circuit board A to be loaded in the loading section 156. This adjustment can be performed by rotating the handles 194, 203 of the inner / outer adjusting means 191, 198. That is, when the handle 194 of the inner adjusting means 191 is operated in the forward and reverse directions, the inner two guide plates 157 are inserted through the female screw bodies 195 and 196 which are screwed to the upper and lower screw shafts 192 and 193.
Since an operation force in the left-right direction is applied to the guide plates 157, the guide plates 157 slide in the left-right opposite directions along the slide rails 163 and 166, and the distance between the guide plates 157 changes.

When the handle 203 of each outer adjusting means 198 is operated in the forward and reverse directions, the outer guide plate 157 slides in the left and right direction via the upper and lower screw shafts 199, 200, the female screw bodies 201, 202, etc. The distance from the guide plate 157 changes. Therefore, each guide plate 157 can be operated only by operating the handles 194, 203.
The interval between them can be easily and arbitrarily adjusted and changed. Also in
The outer adjusting means 191,198 are screw shafts 192,193,199,200 up and down.
Since the operation force in the left-right direction is applied to both upper and lower sides of the guide plate 157, the sliding of each guide plate 157 becomes very smooth. The sliding amount of each guide plate 157 is detected by the pulse generators 207 and 210 and sent to the control box (not shown).

When the printed circuit board A is loaded, the opening / closing cylinder 187 is contracted to close the gate plate 183. When the printed circuit board A is loaded so as to hit the gate plate 183, the printed circuit boards A of the respective loading sections 156 are aligned by the left and right guide plates 157 and the gate plate 183.
Printed circuit boards A can be stacked in order,
There is no fear that B will collapse.

When the loading of the laminated substrate B into the loading section 156 is completed, the opening / closing cylinder 187 is extended to open the gate plate 183, and the loading conveyor motor 175 and the loading conveyor motor 182 are activated to load the loading conveyor. Feed conveyor from 158
The laminated substrate B is sent to 159 in the direction of arrow a in FIG. Then, when the reflection sensor 205 detects the laminated substrate B, the loading conveyor motor 175 and the loading conveyor motor 182 are stopped, and the laminated substrate B is stopped in a state of being transferred onto the loading conveyor 159.

At this time, if each mounting section 8 of the supply device is ready to receive, the loading conveyor 159 loads the laminated substrate B onto the mounting conveyor 10 of each mounting section 8 and transfers it. To do. Therefore, by doing this, the laminated substrate B for three rows
Can be simultaneously loaded into each of the mounting portions 8, and rapid loading is possible.

Even when the laminated substrate B is placed on each placing portion 8 of the supply device, each guide plate is adjusted according to the width of the laminated substrate B.
Adjust the interval between 9 beforehand. Also in this case, if the handles 65, 66 of the inner / outer adjusting means 13, 14 are rotated, the respective guide plates 9 slide left and right along the slide rails 36, 40, and the distance between them can be easily and easily adjusted. It can be adjusted arbitrarily. That is, when the handle 65 of the inner adjusting means 13 is operated in the forward and reverse directions, the upper and lower screw shafts 61 and 63 are rotated, and the inner two screw shafts 68 and 69 are used to move the inner two.
Since the operating force in the left-right direction is transmitted to the one guide plate 9, the guide plate 9 slides in the opposite direction along the slide rails 36, 40, and the distance between the two changes.

When the handle 66 of each outer adjusting means 14 is operated in the forward and reverse directions, the upper and lower screw shafts 62 and 64 are similarly rotated, and the outer guide plates 9 are rotated via the female screw bodies 74 and 75. Also, since the operating force in the left-right direction is transmitted, each outer guide plate 9 slides left and right along the slide rails 36, 40, and the space between the inner guide plate 9 changes.

At this time, since the sandwiching rollers 43 of the mounting frame 11 are rotatably abutted on the respective guide plates 9 from the left and right sides, when the respective guide plates 9 slide left and right, the sandwiching rollers 43 and the like are formed. The operating force in the left-right direction is transmitted to the pair of left and right mounting frames 11 of each mounting portion 8 via the linking means 44, and each of the mounting frames 11 is moved up and down.
The slide rail 46 slides in the left-right direction. Therefore, if the distance between the guide plates 9 is adjusted, the distance between the pair of left and right placement frames 11 and the placement conveyor 10 of each placement portion 8 can be adjusted at the same time. The drive pulley 49 of each mounting conveyor 10 slides on the spline shaft 54 integrally with the mounting frame 11.

On the other hand, when the handles 65 and 66 are rotated,
Since the slide plate 34 supporting each guide plate 9 slides left and right along the slide rail 36, the pinion is inserted through the racks 124 and 125.
123 rotates, the sliding frame 119 slides on the sliding rail 36,
The kicking means 18 moves to substantially the center of each of the left and right mounting portions 8.

For example, when the inner guide plate 9 is adjusted, the rack 124 moves to the left and right integrally with the sliding plate 34 that supports the inner guide plate 9, and the pinion 123 that engages with this rack 124 rotates about the vertical axis. . On the other hand, this pinion 123 is engaged with the rack 125 fixed to the sliding plate 34 that supports the outer guide plate 9, and since the rack 125 is in a stopped state,
The pinion 123 moves left and right along the rack 125 while rotating. Therefore, the sliding frame 119 moves along the sliding rail 46 in the same direction as the inner sliding plate 34 and the guide plate 9, and the moving speed thereof is half the speed of the sliding plate 34 and the guide plate 9. . The same applies when adjusting the outer guide plate 9.

Therefore, even after the guide plates 9 are slid to the left and right to adjust the spacing, the kicking means 18 on both sides are always automatically aligned with the centers of the mounting portions 8. Is very easy to handle, and the center portion of each printed circuit board A can be reliably kicked by the kicking claw 21 at all times, and the displacement of each printed circuit board A at the time of kicking can be prevented. When each guide plate 9 is adjusted to the left or right, the pulse generators 126 and 140 detect the adjustment amount, that is, the interval between the guide plates 9 and send it to the control box.

When the laminated substrate B is placed on each placing part 8, the elevating frame 7 is lowered and the placing conveyor 10 is brought to substantially the same level as the loading conveyor 159 on the loading device side. 12 is started to rotate the mounting conveyor 10 in the direction of arrow b in FIG. Then, the laminated substrate B loaded from the loading conveyor 159 is delivered to the loading conveyor 10 and drawn into each loading portion 8. Then, when the laminated substrate B is completely placed on the mounting portion 8, the mounting conveyor motor 12 is stopped.

Next, the elevating motor 15 is activated, the screw shaft 29 is rotated in the ascending direction to elevate the elevating frame 7, and the laminated board B is controlled to a predetermined level. That is, if the front and rear positions of the kicking means 18 are adjusted according to the length of the printed circuit board A, when the elevating frame 7 is raised and the laminated board B is lifted, the disc 19 is moved to the laminated board B. After coming into contact with the upper surface of the rear end portion, the swing arm 91 is pushed up to rotate around the intermediate shaft 92 in the direction of the arrow c in FIG. Then, when the swing arm 91 becomes substantially horizontal, the proximity switch 98 operates and the lifting motor 15 stops, so that the upper end surface of the laminated substrate B is positioned at the height between the upper and lower feed rollers 128 and 129 of the feeding means 24. Controlled to a matching level.

When the laminated substrate B rises too much, the floating frame 93 is pushed up via the disc 19 and the swing arm 91, so that the floating frame 93 slightly rises along the sliding body 109. The limit switch 112 detects the floating frame 93 and stops the lifting motor 15. Therefore, even if the proximity switch 98 malfunctions, the kicking means 18 is not damaged.

The front and rear position of the kicking means 18 can be adjusted by rotating the handle 116a of the screw shaft 116. That is, when the handle 116a is operated, the screw shaft 116 which is screwed into the female screw body 117 of the base plate 115 rotates, so that the support frame 22 slides in the front-rear direction, and the position of the kicking means 18 can be adjusted back and forth. . When the kicking motors 20 are operated while the disk 19 is in contact with the upper surface of the laminated substrate B, the rotary shaft 89 is rotated through the belt 102, the intermediate shaft 92, and the belt 104 in FIGS. Rotate in the direction of the arrow. Then, each time the rotary shaft 89 makes one rotation, the kicking claw 21 engages with the center of the rear end of the printed board A at the upper end and kicks in the direction indicated by the arrow d.
A moves to the feeding means 24 side.

At this time, if the feed motor 25 and the feed conveyor motor 17 are activated, the front end of the printed board A enters between the vertical feed rollers 128 and 129 of the feed means 24, and the feed means 24 feeds the printed board A to the feed conveyor. After being sent onto the printed circuit board 16, the printed circuit board A is supplied by the supply conveyor 16 to the washing machine at the rear end.

Then, by controlling the kicking motors 20 so that the kicking claws 21 of the respective kicking means 18 simultaneously kick the printed circuit boards A of the respective mounting portions 8, the printed circuit boards A are simultaneously supplied in three rows. Moreover, if there is a time difference between the kicking claws 21 of each kicking means 18, three rows of the printed circuit boards A can be alternately supplied with the time difference. Moreover, the distance between the three rows of printed circuit boards A only corresponds to the thickness of the guide plate 9, and even when the widths of these printed circuit boards A differ, they should be gathered at regular intervals on the center side of the whole. Because we can supply
The printed circuit boards A in each row are not too far apart from each other.

In the embodiment, the printed circuit board is installed in the washing machine.
Although the three-row type supply device for supplying A has been illustrated, the present invention is not limited to this. That is, as long as it is a thin plate material, a material other than the printed circuit board A can be similarly supplied.
Also, if it is a double row type, it may be two rows, four rows, five rows, etc. For example, in the case of a two rows type, it can be similarly implemented by fixing the central guide plate 9.
