By being able to reciprocate across the transfer conveyor 13 and moving up and down by the expansion and contraction of the cylinder 27, the single materials t in the upper stage can be transferred to the transfer conveyor 13 two by two.

Further, the height detecting tool 3 lowers the base rod 31 together with the operating rod 33 by extending its cylinder 30 before the lifting tool 12 is raised, as shown in FIG. Therefore, the rising upper surface of the single block T pushes up the operating rod 33 until the detector 34 is activated. As the detectors 34 and 34 operate, the lifting tool 12 stops rising, and the height detector 3 detects the proximity of the operating rod 33. The height is kept constant as measured by the detector 34. After the measurement, the cylinder 30 is reduced in size and the operating rod 33 is lifted as shown by the dashed line in FIG. prevent.
It should be noted that the cylinder 50 is extended every time the transfer of the single material t in each stage is completed, and its raised position is kept constant.

The spacer dispensing tool 5 according to the present invention extends the cylinder 66 and moves the sweeper 53 when the transfer of the single material t placed on the spacer s is completed and the spacer s is exposed on the upper surface of the single material t. The contact portion 62 of the spacer s is tilted to a height where it comes into contact with the spacer s. Thereafter, the spacer s can be dropped into one of the receiving boxes 71 by driving the deceleration motor M2 and moving the part 62 together with the traveling base 51 along the longitudinal axis direction of the single material t. After passing, it stops at that position, and when the next spacer s is exposed, the other cylinder 67 is extended and the tool 63 is lowered and returned to feed the spacer s into the other receiving box 71. can.
