And a conveying means 1 comprising a driven roller 12, an endless belt 13 wound and stretched between the rollers 11, 12, and a sorting conveying section 2 provided below the conveying means 1. The sorting transport unit 2 includes a drive roller unit 21 connected to a motor, a lower magnet roller unit 22 corresponding to the driven roller 12, and a belt unit 23 wound around the two roller units 21 and 22. Consisting of The sorting transport unit 2 is set such that the belt 23 moves in the direction opposite to the chip transport direction of the transport unit 1. The chips D supplied onto the belt 13 of the conveying means 1
Transported to the side. If the terminal portion (nickel-plated material) D1 of the chip D is properly plated and has a certain plating thickness, when the chip D reaches the end of the belt 13, it falls to the lower magnet roller portion 22 side. The magnetic roller 22 is attracted by the magnet roller 22 and reverses downward with the rotation of the magnet roller 22. On the other hand, when the plating process of the chip terminal portion D1 is not appropriate and the plating thickness is thin, the chip terminal portion D1 is not attracted to the magnet roller portion 22, falls down as it is, and is stored in the defective product receiving box A. As a result, non-defective products (chips having good adhesiveness to solder) and defective products (chips having poor solder paste) are sorted and sorted. In FIG. 3, the sorting transporting section 2 is provided with three transporting sections 2a, 2b, 2c whose transport directions are opposite to each other, in three stages in the vertical direction.
Therefore, the chip D sucked by the uppermost transport unit 2a (on the side of the transport unit 1) and inverted downward is transferred to the magnet roller unit 22.
At the point when the suction force of
After being dropped and conveyed, it is again suction-reversed by the middle magnet roller unit 22, then dropped on the belt 23 of the lowermost conveyance unit 2 c, conveyed, and turned downward by the lower magnet roller unit 23. , Falls at a point where the attractive force of the magnet roller portion 23 is released, and is stored in the non-defective product receiving box B.

Therefore, if a part of the two chips E and F among the plurality of chips supplied on the belt 13 of the conveying means 1 is transported in a state of being vertically overlapped, the two chips E and F flow in an overlapping manner. Assuming that both chips E and F are non-defective products (the plating thickness of the terminal portion D1 satisfies the standard), the chip E located below the overlap is the magnet roller portion 2 of the sorting / conveying portion 2.
2, the chip F located above the overlap is housed in the non-defective product receiving box A without being absorbed by the magnet roller portion 22, and is sorted out. There were disadvantages, such as the inability to execute completely.

合であっても、良品・不良品が完全に選別される。In the chip sorting apparatus having such a configuration, for example, the chips D supplied from the hopper (feeder) C onto the belt 13 of the conveying means 1 are conveyed to the driven roller 12 side. If the plating of the terminal portions D1 at both ends of the chip D is not appropriate (when the nickel plating thickness is small), the chip D that has reached the end of the driven roller 12 is not attracted to the magnet roller 22 located above, It falls from the conveyor belt 13 as it is and is stored in the defective product receiving box A. On the other hand, when the plating process of the terminal portion D1 of the chip D is appropriate (when the nickel plating thickness is large), the terminal portion D1 is attracted to the magnet roller portion 22, lifted and inverted upward,
The sheet is conveyed to the driven roller section 21 side on the conveyance selection belt 23. During this conveyance, the chip D is again attracted by the magnet roller portion 22 of the middle stage 2b, lifted and inverted. Further, the driven roller portion 21 is placed on the belt 23 of the middle stage 2b.
While being conveyed to the side, it is attracted and inverted by the magnet roller unit 22 of the upper stage 2c, is conveyed on the upper belt 23, and is moved from the position where the attraction force of the magnet roller unit 22 is released (the drive roller unit 21 of the upper stage 2c). It is stored in the non-defective product receiving box B below. As shown in FIG. 2, if a plurality of chips (two good chips E and F) supplied on the conveyor belt 13 are conveyed in an overlapping manner and reach the lower portion of the magnet roller unit 22, first, The chip F located on the upper side is attracted and lifted at the tip end side of the magnet roller portion 22, and is inverted upward. Subsequently, the chip E located on the lower side is sucked and lifted at the rear end side of the magnet roller portion 22 and is inverted upward. Therefore, even if a plurality of non-defective chips are transported in an overlapping manner, non-defective and defective products are completely selected.

Although the example in which the sorting transport unit 2 is configured by arranging the steps 2b and 2c vertically in a stepwise manner is shown, this is achieved by sequentially weakening the magnet force from the lower transport unit 2a to the upper transport unit 2c to reduce the chip. This is because the quality of D is further selected step by step with high accuracy. Therefore, in the case where the non-defective product and the defective product are finished by one-time sorting, it is a matter of course that the sorting and transporting unit 2 can be executed only by a single transporting unit (the lower transporting unit 2a).

A chip sorting transport unit that transports the belt to the head is provided, and a good-quality chip with a large plating thickness is attracted and turned upward by a magnet roller unit that is arranged above the driven roller. Defective chips with incomplete processing (thin plating thickness) fall from the end of the belt of the conveyor to the defective receiving box, and the non-defective chips are attracted by the magnet roller, lifted upside down, and turned upside down. Dropped and stored in a box. In addition, even when a plurality of non-defective chips are transported in an overlapping manner, after the upper chip in the overlapping manner is sucked and lifted,
Subsequently, the chip located on the lower side is sucked and lifted upside down behind the magnet roller portion. Therefore, the present invention has an excellent effect of attaining the object of the invention, such as eliminating the disadvantage that a good chip conveyed in an overlapped form is shaken off to a defective product as in the related art and realizing high-precision sorting.
