〔Example〕

Fig. 1 is a perspective view showing one embodiment of the present invention;
The figure is a perspective view showing an example of the stake S, and Figures 3a, b, c, d, and e are explanatory diagrams showing the operating states of each mechanism in Figure 1, where A is a front view and B is a side view. , C shows a plan view. In the figure, reference numeral 1 denotes a guide mechanism that is divided into five rows by a partition plate 1a, and each row accommodates stacks S containing semiconductor devices in a stacked state (for example, if one row is 20, five rows are used).
100 pieces), the partition plates are formed of flat plates at opposing positions in order to guide the vertical movement of the accommodated stakes S.

2 is a first movable block that holds the lowermost stake S housed in the guide mechanism 1 and controls its descent. Reference numeral 3 denotes an eccentric cam which drives the vertical movement of the first movable block 2. Diagrams of its operating state are shown in the diagrams in FIGS. 3a, b, and c. 4 is a push-out mechanism for the stopper pin 5;
The first movable block 2 is lowered by the operation of the eccentric cam, and the stake S housed in the guide mechanism 1 is moved downward.
When the stake S descends to a certain position, insert the stopper pin 5 into the groove of the second stake S from the bottom (the third
(B and C in Figure b), hold the stake S.
6 is an intermediate stage, and the second stage from the bottom, housed in the guide mechanism 1, is connected to the stopper pin 5.
When the first movable block 2 is further lowered by the operation of the eccentric cam 3, as shown in FIG. 3c, the stake held by the first movable block 2 is placed. 7 is a second movable block that transfers one end of the stake S placed on the intermediate stage 6 to the grooves 9 (9a, 9b, 9c, 9d) provided at 90° intervals in the rotary holder 8; Move the remaining stakes one by one towards the end. Reference numerals 10, 11 and 12 are drive mechanisms consisting of an eccentric cam and a movable arm;
The movable block is driven in a cycle of raising-feeding-lowering-return (in the direction of the arrow shown in FIG. 3d). 13
is a slide block, and the state when the stake S is transferred to the groove 9 of the rotary holder 8 is the state when the stake S held in the groove 9 is rotated by 90 degrees from 9b to 9c in FIG. 3d in the direction of the arrow. Slide. 14 is a holder and slide block 1
3, the stake held in the groove 9 is held and tilted, and the IC stored in the stake is supplied to the chute 15. Reference numeral 16 denotes an empty stake storage section, and 17 a delivery bar for feeding empty stakes into the empty stake storage section.

Next, the operation of this embodiment will be explained.

The lowest stake S is the first movable block 2
The sticks in the second and higher rows from the bottom are stacked in appropriate numbers in each row in the guide mechanism 1, but this state is not shown in FIG. Now, as the cam 3 is operated and rotated by a power mechanism (not shown), the third
When the state shown in Fig. 3A changes to the state shown in Fig. 3B, and the first movable block 2 descends a certain distance, the pushing mechanism 4 operates in conjunction with this, and pushes out the stopper pin 5. The state shown in FIG. 3a (b) changes to the state shown in FIG. The stakes S above the level are held so that they do not fall from that position.

When the eccentric cam 3 rotates from this state and the first movable block 2 further descends, the state shown in FIG.

Next, the drive mechanisms 10, 11, and 12 are operated, and the second movable block 7 is driven in cycles in the order of ascending, forwarding, descending, and returning as shown by the arrow in FIG. 3d, and is placed on the intermediate stage 6. Status S
One end of the stick is transferred to the groove 9 (9a in this case) near the rotary holder 8, and the remaining stakes are moved one by one in the direction of the ends. This operation of cycle driving of the second movable block is repeated every time the rotary holder 8 rotates 90 degrees. In this embodiment, since the stake S placed on the intermediate stage 6 is removed after 5 repetitions, the eccentric cam 3 operates in conjunction with this, and the guide mechanism 1 The lowest stake housed in is sent to the intermediate stage 6. Thus rotary holder 8
rotates, and when the groove 9 holding the stake comes to a position opposing the slide block 13, the slide block 1, which is interlocked with the rotation of the rotary holder 8,
3 is actuated by its drive arm 13-1, and slides the stake S held in the groove from the dotted line position to the solid line position (from right to left in the figure) as shown in the bottom view of Figure 3e, and the holder Send it to 14.

The holder 14 is interlocked with the slide block 13,
When the stake is fed in, it is rotated 90 degrees as shown in Figure 3e, changing the held stake S from the horizontal state (shown with solid lines) to the vertical state (shown with dashed lines).
and supply the stored IC to the chute 15. When the supply of IC to chute 15 is finished,
In conjunction with this, the holder 14 returns to its original state. At the same time, the slide block 13 operates, and the empty stick S held by the holder 14 is pulled out from the holder 14 and returned to its original position in the rotary holder 8 (groove 9c in FIG. 3d).

When the rotary holder 8 is rotated 90 degrees from the above state, a delivery bar 17 (Fig. 3 d ), the empty stick S' held in the groove 9 (9c in FIG. 3d) of the rotary holder 8 is fed into the empty stick storage section 16.

Each of the above operations is repeated, and the IC is continuously and automatically supplied to an automatic measuring device, an automatic printing device, etc. via the chute 15.

In the above, it is possible to add a mechanism that automatically replenishes the sticks to the guide mechanism 1, but as in this embodiment, it is possible to accommodate 100 sticks at a time (5 rows, 20 sticks stacked in each row). Even so, it takes a considerable amount of time to complete the supply of ICs for all stakes, so even if the supply is handled by a worker, the process can be done with fewer man-hours.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to continuously and automatically supply semiconductor devices stored in a stake to automatic measuring equipment, automatic printing equipment, etc., which reduces man-hours and has practical effects. is large.
