If the support arm 55 and the support plate 63 do not rotate, the number of the connecting rod 61 may be one.

When the printed board 1 is supplied to the next step in the supply device having the above-described structure, the following operation is performed. First, the printed circuit boards 1 are placed on the lift table 3 in a laminated manner, the suction feeding means 7 are adjusted so as to correspond to the left and right sides of the printed circuit board 1, and the two-sheet feeding preventing means 8 is adjusted to the thickness of the printed circuit board 1. Adjust accordingly.

When adjusting the suction feed means 7, the suction feed means 7 is rotated around the support shaft 25 to disengage the engaging body 39 from the positioning body 26, and the support shaft 25 is adjusted to the width of the printed circuit board 1. After sliding in the axial direction, the engaging body 39 is moved to the positioning body 26.
To engage from below. Therefore, it is possible to easily cope with the printed boards 1 having different widths. Printed circuit board
When a large number of small holes for mounting parts are drilled in 1, the position of the suction feed means 7 may be adjusted to the left or right according to the distribution state of the small holes.

When adjusting the two-sheet feeding prevention means 8,
Lift the contact body 60 against the spring 64 to remove it from the setting portion 58, and turn the disc 59 around the support shaft 57 so that the setting portion 58 corresponding to the thickness of the printed circuit board 1 corresponds to the contact body 60. , Its setting section 58
The contact body 60 is engaged with the upper side. This allows the setting section
The vertical position of the regulation body 53 is determined by the depth of 58, and the regulation body 53 can be easily adjusted according to the thickness of the printed board 1.

When these adjustments are completed, each part of the supply device is activated to start the supply operation of the printed circuit board 1. During the feeding operation, the lifting drive motor 4b raises the lifting platform 3 and when the uppermost printed circuit board 1 on the lifting platform 3 reaches a predetermined position, the position sensor 17 detects the uppermost printed circuit board 1. The lifting drive motor 4b stops.

On the other hand, the opening / closing valve 51 on the suction means 6 side repeats the opening / closing operation at a predetermined time interval set in advance, and after the uppermost printed circuit board 1 reaches the predetermined position,
When the on-off valve 51 is opened, the suction force of the blower 45 causes the suction means 6 to suction the downstream end of the uppermost printed circuit board 1 upward by vacuuming. Then, when the downstream end of the uppermost printed circuit board 1 is lifted up, the suction rotation belt 21 of the suction feeding means 7 sucks the printed circuit board 1 to the lower surface side by the same vacuuming.

When the suction rotation belt 21 sucks the printed circuit board 1, first, the portion of the suction rotation belt 21 corresponding to the downstream side suction portion 22 is sucked up by the suction means 6 and is raised to the downstream side of the printed circuit board 1. Adsorb the edge, then
The printed board 1 is sucked by the entire lower surface side of the suction rotation belt 21 corresponding to the downstream suction section 22 and the upstream suction section 23.

The printed circuit board 1 adsorbed by the suction rotation belt 21 is moved by the rotation of the suction rotation belt 21 to the feed conveyor.
Move to 5 downstream. Then, when the downstream end of the printed board 1 reaches the feed conveyor 5, the suction rotation belt 21 is sequentially removed from the downstream suction section 22, so that the printed board 1 is delivered to the feed conveyor 5. After that, it is supplied to the downstream side by the feed conveyor 5.

When the suction rotation belt 21 sucks the printed circuit board 1, the suction sensor 38 detects the printed circuit board 1 and the elevating drive means 4 raises the elevating table 3 so that the suction means 6 moves the printed circuit board 1 up. The printed circuit board 1 is sucked up and sucked by the suction rotation belt 21 and sent to the feed conveyor 5. After that, the same operation is sequentially repeated, and the printed circuit board 1 on the lifting platform 3 is sequentially sucked from the upper side and supplied to the downstream side at a predetermined time interval.

When the uppermost printed circuit board 1 on the lifting platform 3 is displaced to the upstream side, the position sensor 17 may detect a few printed circuit boards 1 from the uppermost position. In this case, when the elevating table 3 is raised until the position sensor 17 detects the printed circuit board 1, the uppermost printed circuit board 1 comes into contact with the lower surface side of the suction rotation belt 21 of the suction feeding means 7 and the suction feeding means. The upstream side of 7 is pushed up around the support shaft 25.

However, since the downstream end of the suction feed frame 18 of the suction feed means 7 descends and shuts off the light from the light emitter 52a to the light receiver 52b, the push-up sensor 52 is used by the suction feed means.
Detects the push-up of 7 and stops the supply operation of printed circuit board 1. Therefore, it is possible to prevent damage on the suction feed means 7 side, clogging of the printed circuit board 1, and the like.

If the feeding device having such a structure is used,
There is no need to move the suction feed means 7 up and down, or to reciprocate the suction feed means 7 in the feed direction, and the structure of the entire device can be simplified and downsized, and the printed circuit board 1 on the lift table 3 is sequentially moved upward. It can be adsorbed from and can be efficiently supplied in a short time.

Further, the printed circuit board 1 by the sucking means 6
Since the downstream end of the printed circuit board 1 is sucked up and the printed circuit board 1 is sucked by the suction rotation belt 21, the uppermost printed circuit board 1 is easily separated from the lower printed circuit board 1 and two or more The printed circuit board 1 of is not adsorbed and sent out.

Even if the suction rotation belt 21 sucks two or more printed circuit boards 1, when it moves slightly to the downstream side, the regulating member 53 is provided on the downstream side of the second or less printed circuit boards 1. Engage with each other to regulate the movement of the printed circuit board 1 to the downstream side, so that the two feeds of the printed circuit board 1 by the suction rotation belt 21 can be reliably prevented.

When the length of the printed circuit board 1 is short, the on-off valve 50 connected to the upstream suction section 23 is closed, and the downstream suction section 22 is used to move the suction rotation belt 21 to the printed circuit board 1.
Adsorb 1. When the width of the printed circuit board 1 is small, one suction feeding means 7 and, in particular, the suction feeding means 7 on the guide plate 16 side are used.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the embodiments. For example, two suction feed means 7 are provided so that the position can be adjusted in the left-right direction, but the suction feed means 7 may be one piece or three or more pieces. In that case, the suction feed means 7 can be fixed so that the position cannot be adjusted in the left-right direction.

Further, the suction rotation belt 21 of the suction feed means 7
Can be one. One or three or more suction units may be provided in the rotation direction of the suction rotation belt 21. The suction feed frame 18 may be formed in a plate shape, and the downstream pulley 19, the upstream pulley 20, the suction rotation belt 21, and the suction portions 22 and 23 may be provided on one side or both sides of the suction feed frame 18. Although the suction means 6 and the two-sheet feeding prevention means 8 are attached to the suction feeding frame 18, they may be provided separately from the suction feeding means 7. The on-off valves 49 to 51 may have any structure.

In the embodiment, the supply device for supplying the printed circuit board 1 is illustrated, but the printed circuit board 1
The same can be applied to a feeding device for a plate material other than 1. That is, as long as it is a plate material that can be sucked up by the suction means 6 and sucked by the suction feed means 7, it can be applied to the case of supplying a thin plate material other than the printed circuit board 1 or the case of supplying a thicker plate material. .
