A plurality of trays are stored on the tray shelf 2 in this condition. As shown in Fig. 2, the parts storage tray 1 is bottomless with no plates on the top and bottom surfaces, has internal partitions of a constant pitch both vertically and horizontally, and has an interior with a chuck 3 on one end surface. Tray 4 and
As shown in FIG. 3, it is composed of a rectangular outer tray 5 with no upper surface and no lateral surface. Figure 4 shows
It shows a state in which the inner tray 4 of FIG. 2 and the outer tray 5 of FIG. 3 are combined, and the parts storage tray 1
shows the structure of In this state, the inner tray 4 can be slid along the bottom plate of the outer tray 5 in the direction of arrow A. On the other hand, on the front side of the tray shelf 2, a handler 8 is provided which carries a tray drawer/storage mechanism 6 and a shutter mechanism 7 and moves along the tray shelf 2 in the X-axis and Z-axis directions. This handler 8 moves along the X-axis guide 9 when moving in the X-axis direction. Between the tray shelf 2 and the handler 8, there is a parts conveying belt 10 that conveys the parts after being delivered in the direction of arrow B. At this terminal end, there is a bucket 1 for storing the parts transported by the parts transport belt 10.
There is an elevator mechanism section 12 that lifts and lowers one revolution in the Z-axis direction while holding the elevator. The bucket 11 is
When it comes to almost the same height as the upper end of the elevator mechanism section 12, it rotates by itself due to the operation of the elevator mechanism section 12 and throws the parts into the chute 14. At the outlet of the bagging machine 13, there is a takeout belt 15 for taking out the bagged parts. The control unit 16 controls the electrical components of each of these mechanisms.
(details omitted). The bagging machine 13 includes a printer (omitted) that prints parts names, quantities, orders, etc. on bags.
Printing is performed according to the parts to be dispensed according to a signal from the control section 16. FIG. 5 shows the operation of the tray drawer/storage mechanism 6 and the shutter mechanism 7 mounted on the handler 8 from the component storage tray 1.
It is an explanatory diagram when paying out a predetermined number of. Inner tray jack 18, clamp 19 and pulse motor A
Reference numeral 20 is provided in the tray drawer/storage mechanism section 6, and the inner tray chuck 18 chucks the chuck portion 3 of the inner tray 4, and the outer tray 5 is clamped by the clamp 19. The shutter 21 is
It is moved by a pulse motor B22, and the entire body is raised and lowered by an air cylinder 23. these are,
It is provided in the shutter mechanism section 7. A parts storage box 24 for storing parts is provided on one end surface of the shutter 21.
The bottom cover 25 at the bottom automatically opens and closes. Next, the operation will be explained. Handler 8 is
It moves in the X-axis and Z-axis directions in response to a component delivery signal from the control unit 16, and is positioned at the component storage tray 1 storing the corresponding component. After positioning, the tray drawer/storage mechanism section 6 operates to pull out the component storage tray 1 from the tray shelf 2. In this state, the air cylinder 23 is turned on and the shutter 21 is pressed against the bottom of the inner tray 4. At this time, the chuck portion 3 of the inner tray 4 is chucked with the inner tray chuck 18, and the outer tray 5 is clamped with the clamp 19. Thereafter, a signal indicating a predetermined number of parts to be dispensed is received from the control unit 16, and after pushing out the inner tray 4 in the direction of arrow C using the pulse motor A20, the shutter 21 is moved in the direction of the arrow D using the pulse motor B22.
move in the direction. Therefore, the parts 17 placed in the inner tray 4 fall into the parts storage box 24 by the distance traveled by the shutter 21. Next, the shutter 21 is returned to its origin in the direction of arrow E by rotating the pulse motor B22 in the reverse direction, and the bottom surface of the inner tray 4 is covered again.
Further, the pulse motor A20 similarly rotates in the reverse direction to return the inner tray 4 in the direction of arrow F by the distance pushed out in the direction of arrow C. Now that a predetermined number of components 17 have been stored in the component storage box 24, the handler 8 is lowered in the Z-axis direction to a predetermined height above the component transport belt 10.

As soon as the bottom cover 25 is opened, the parts fall onto the parts transport belt 10, so the parts transport belt 10 is rotated in the direction of arrow B, and the parts are dropped again into the bucket 11 of the elevator mechanism section 12 installed at this exit. This is detected by, for example, a timer (not shown) provided in the control section 16, and after the component 17 is reliably dropped into the bucket 11, the elevator mechanism section 12 is raised. Since the bucket 11 rotates by itself at the upper end of the elevator mechanism section 12, the parts 17 are transferred to the chute 14.
This is detected by, for example, a sensor (not shown), and the bagging machine 13 packs the bag into a pre-printed bag. Since the packed items fall onto the take-out belt 15, they are fed one after another to make them easier to take out. Next, after stopping the chuck of the inner tray chuck 18 and the clamp 19, and turning off the air cylinder 23,
The Z axis of the handler 8 is raised again to a predetermined position, the tray drawer/storage mechanism section 6 is rotated in the reverse direction, and the component storage tray 1 is stored on the tray shelf 2. In this way, by sequentially applying signals from the control section 16 and executing the process, a predetermined number of predetermined parts can be dispensed and packed into bags.

〔Effect of the invention〕

The automatic parts dispensing device of the present invention stores a plurality of parts in a parts storage tray consisting of a combination of an inner tray and an outer tray, stores the parts on a tray shelf, and controls the X and Z axes of the tray shelf using a control unit. By managing data on how many types of parts are stored in each location and operating the tray drawer/storage mechanism and shutter mechanism mounted on the handler, a predetermined number of parts can be automatically dispensed. Since it can be packaged in bags, it has the effect of reducing parts counting errors, mismatching of slips and parts, making paperless slips, and further reducing labor.
