The operation of the drawer device 6 in 9 to S12 is shown in FIG.
Etc. will be used to describe in more detail.

As shown in FIG. 9, the operation of pulling out the drawer 5 is started in S20. The drawer 5 is slid stepwise by the action of the stopper mechanism 30 in the drawer length in units of the pitch of the accommodating portions 27, and the accommodating portion 2 having the necessary number of steps is formed.
7 is drawn out of the housing 23.

As shown in FIGS. 4 and 10, when the drawer 5 is closed, the first and second sensors 51 and 52 are off.
The third sensor 53 is shielded by the opening / closing plate 43 and is turned on. The open / closed state of the drawer 5 is determined in the control means 8 by the combination of the signals of these three sensors 51, 52, 53. If the open / closed state of the drawer 5 determined in the control means 8 is called an open / close flag, the drawer 5
When is closed, the open / close flag is ON.

In S22 of FIG. 9, the open / close flag of the designated drawer 5 is determined. When the open / close flag of the designated drawer 5 changes from ON to OFF, it means that the designated drawer 5 has been normally withdrawn. Drawer 5 other than specified
When is pulled out, an alarm sounds at S23.

When the drawer 5 is slid in the drawing direction, each timing plate 4 provided for each storage section 27.
1 passes through the first sensor 51 and the second sensor 52 in this order. Therefore, the first sensor 51 and the second sensor 52
9 is called a first timing flag and a second timing flag in the control means 8, respectively, S2 of FIG.
4, S25 and as shown in FIG. 10, when the drawer 5 is being drawn out, the second timing flag is turned on after the first timing flag is partially overlapped. Since the signals of S24 and S25 are repeatedly output and given to the control means 8 according to the number of stages of the storage unit 27 that has been pulled out, the main control unit 10 stores the number of stages of the drawer 5 that has been pulled out.

Drawer 5 to the required position as shown in FIG.
When the card is pulled out (S26), a new case 2 of the same ticket type is inserted into the empty storage section 27 (S27). When the case 2 is inserted, the leaf spring 42 is pushed, and the tip of the leaf spring 42 projects to the outside of the drawer 5 (S28). And drawer 5
Is pushed back (S29).

When the drawer 5 is slid in the pushing-back direction, each timing plate 41 passes through the second sensor 52 and the first sensor 51 in this order. Therefore, as shown in S30, S31 and FIG. 10 of FIG. 9, every time each timing plate 41 passes, the first timing flag (second sensor 52) is followed by the first timing flag ( The first sensor 51) is turned on while partially overlapping. Also, every time the leaf spring 42 passes the third sensor 53, the case presence / absence flag is confirmed to be ON or OFF in the control means 8 as shown in S32. That is, when the first sensor 51 is turned on while the second sensor 52 is turned on, it is confirmed whether the third sensor 53 is turned on or off. It is determined that Case 2 is inside.

Depending on the number of stages of the storing portion 27 to be pushed back, S30,
The signals of S31 and S32 are repeatedly output and given to the control means 8. In S33, the first and second sensors 51, 52 are OFF and the third sensor 53 is turned ON by being blocked by the opening / closing plate 43. As a result, when the opening / closing flag is determined to be ON, control is performed based on the count result of the signal. The mapping memory 17 of the means 8 is rewritten. That is, the main control unit 10 of the control means 8 holds the information about how many cases 2 have been inserted before withdrawing, and the number of cases withdrawn at the time of withdrawing and the case 2 when the drawer 5 is pushed back. You can get information about how many are in it. From these information,
It is determined how many cases are currently in the drawer 5, and the contents of the mapping memory 17 are rewritten.

As described above, by counting the ON / OFF signals of the third sensor 53 indicating the presence / absence of the case 2 in each storage section 27 under a constant condition, the number of cases 2 stored, the number of payouts, the number of stocks, etc. I understand.

Further, in order to prevent an error from occurring when the drawer 5 is repeatedly drawn in and out by an irregular operation, the third
The case presence / absence flag is confirmed using the ON / OFF signal of the sensor 53 only when pushing back and not counting when pulling out.

Further, since the drawer device 6 of this embodiment has the stopper mechanism 30, the drawer slide operation is performed for each number of stages of the storage section 27, and the positioning is reliable. For this reason, there is little risk that an erroneous signal is output from each sensor due to a halfway operation of the drawer 5, and there is an error in counting the slide amount, the sliding direction, and the number of cases of the drawer 5 determined by the signals from these sensors. It is hard to enter.

[0041]

Since the drawer device of the work management apparatus according to the present invention is arranged such that the drawers in which the works are arranged side by side in the drawing direction are drawn out in stages in accordance with the arrangement pitch of the works.
The position can be fixed by pulling out only the amount necessary for putting in and out the work. Therefore, it is possible to realize a drawer device having an ideal function as a work storage unit in a work management device that automatically counts and manages the number of works in a drawer by using various sensors and the like.
