Abstract

PURPOSE:To enable an empty container to be supplied efficiently with no space by arranging the empty container, placed in an empty container supply line, in a standby condition in a position corresponding to the respective position of a storage container. CONSTITUTION:Connecting an empty container supply part 37 to one end side of a supply line of an empty container 36, it is supplied, and the supplied empty container 36 is arranged in a standby condition so as to correspond to a position where storage containers 33a-33d are arranged on the supply line of the empty container 36. Consequently, enabling the empty container 36 to be supplied instantaneously when the storage container 33 is discharged, the empty container 36 can be positioned corresponding to each storage container 33a-33d only by feeding the container in the supplying direction by the space of the storage container 33. As the result, because the empty container 36 can be supplied efficiently further because the empty container supply part 37 is required only in one quantity, small space is only required for a storage part 30 of plate- shaped electronic articles to the container.

Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a container supply method in a plate-shaped electronic article inspection system, and more specifically, the present invention relates to a container supply method for a plate-shaped electronic article inspection system. In an inspection system that inspects two electronic items and stores them in containers according to the test results arranged in the storage section, the space of the storage section where the containers are placed can be reduced, and empty containers can be replenished. This invention relates to an empty container supply system that can be used efficiently.

[Prior art] As a floppy disk, 5.25 inch or 3.
．． Although 5-inch disks are increasingly being used, the manufacturing process for these floppy disks requires an inspection process, which requires a lot of time, and the quality of each floppy disk is An important issue is how to efficiently inspect disks.

Therefore, a number of disk characteristic measuring devices (or inspection units) for measuring the electrical characteristics of floppy disks are provided as a group, and floppy disks are loaded and inspected in parallel.

In such cases, a large number of floppy disks that have been inspected are continuously ejected, and the continuously ejected floppy disks are often stored in containers with their cases or jackets stacked vertically. .

In this case, since containers must be provided depending on the measurement results, the storage space inevitably becomes large.

[Problem to be solved] In such a conventional system, in order to arrange a container for each measurement result, a container supply line and a discharge line are provided according to the measurement result, and the storage container is efficiently discharged. The system is designed to replenish empty containers. Additionally, in order to process as many floppy disks as possible at once, there is a tendency for containers themselves to become larger and accommodate many floppy disks at once. Therefore, when viewed from the inspection system as a whole, the space of the container storage section becomes larger and larger, resulting in an increase in the size of the system.

This invention solves the problems of the prior art, and aims to provide a container feeding method in a plate-shaped electronic article inspection system that can efficiently feed empty containers without taking up much space. do.

[Means for Solving the Problems] To achieve the above object, the container storage system for plate-shaped articles of the present invention has a configuration in which a storage section is arranged in a row adjacent to the ejection line for electronic articles of the measuring device. A plurality of storage containers are erected facing the discharge line, an empty container supply line is commonly arranged for the plurality of storage containers along the row, and one end of the empty container supply line is connected to the empty container supply line. The empty containers on the empty container supply line are placed on standby at positions corresponding to the respective positions of the storage containers.

[Function] In this way, an empty container supply line is commonly placed adjacent to a row of storage containers arranged according to the measurement results,
An empty container supply unit is connected to one end of the empty container supply line to supply empty containers, and the supplied empty containers are placed so as to correspond to each position where storage containers are placed on the empty container supply line. By arranging it in a standby state, when a storage container is ejected, an empty container can be immediately supplied, and the position of the supplied empty container is one of the positions arranged in a row, so the direction of supply can be changed. Empty containers can be positioned corresponding to each storage container by simply sending them by the distance between the storage containers.

As a result, we can efficiently supply empty containers,
Furthermore, since only one empty container supply section is required, the space required for storing the plate-shaped electronic articles in the container is small.

[Example Code] An example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a plan view of the container feeding method in the plate-shaped electronic article inspection system of the present invention applied to a floppy disk container storage section, and FIG. 2 shows the empty container feeding procedure. FIG. 3 is an explanatory diagram of the container supply/discharge section in the part where floppy disks are accumulated and stored, FIG. 4(a) is a side view of the hand and ring mechanism for empty containers, and FIG. 4(b) FIG. 2 is a plan view of the empty container feeding mechanism.

In FIG. 1, 30 is a container storage section for floppy disks, 31 is a belt conveyance line for conveying inspected floppy disks, and along this belt conveyance line 31, the floppy disks are deposited in three columns. There are four floppy disk accumulation sections.

The belt conveyance line 31 includes two guide rails 31a,
It has a claw feed bell (31c) having a claw protruding from the lower side of the belt conveyor line 31, and 2 is a floppy disk discharged from the inspection apparatus side conveyed by this belt conveyance line 31.

The four floppy disk accumulation sections are arranged in a line at predetermined intervals, and these four locations, from the left side of the drawing, are the floppy disk accumulation section 32d9 of passing level I floppy disks. A stacking section 32b9 collects floppy disks whose surfaces pass the level mff11L$32cv, and a stacking section 32d collects floppy disks whose surfaces fail.

The inspected floppy disks 2 sent through the belt conveyance line 31 are dropped onto the lower side of the belt conveyance line 31 by the dropping and pushing mechanisms 31c located on the opposite side and below the stacking section, and are dropped onto the lower side of the belt conveyance line 31. The floppy disks are extruded and deposited in the floppy disk accumulation section.

As shown in FIG. 1, the falling push-out mechanism 31c includes a locking pawl opening/closing mechanism 3 whose locking pawl portions are arranged in the cut portions of the two guide rails 31a and 31b that are larger than the width of the floppy disk 2; As shown in Figure 3, the guide rail 31
It consists of a packet 5 located below the stacks 31a and 31b, and an extrusion cylinder 4 that pushes out the packet 5 to the previous accumulation section.

As shown in FIG. 1, between and behind each of these stacking parts, there is a storage container 33a for floppy disks of passing level 1, and a storage container 33b for floppy disks of passing level 2.

Four storage containers, ie, a storage container 33c for floppy disks whose surface has passed and a storage container 33d for floppy disks whose surface has failed, are correspondingly arranged in a line.

And each of these storage containers 33 al 33 b+
Behind 33c and 33d, there is a container accumulation and stacking section 3 from which storage containers containing floppy disks are discharged.
4a, 34b, 34c, and 34d are provided correspondingly.

Moreover, each storage container 33 a, 33 b, 33 c, 33 d in a row adjacent to these discharge lines 31
An empty container replenishment line is provided on the upper side of the storage containers so that the empty containers 36 are distributed to the positions of the respective storage containers on a straight line connecting these storage containers. In order to form this empty container replenishment line, an empty container feeding mechanism 35 is arranged along this replenishment line. On the right side of the drawing, an empty container supply section 37 is provided adjacent to the storage container 33d.

Here, the empty container 36 is supplied to this empty container supply section 37.
From there, the empty container is supplied to an empty container feeding mechanism 35 arranged along the empty container supply line. Usually, empty container 36
is sent by an empty container feeding mechanism 35 arranged along the empty container supply line, and is sent to each storage container 33aw 3.
3b+33c+33d are arranged in a standby state above each storage container 33a, 33b, 33c, 33
d and upper F overlap.

And each storage container 33a, 33b+33c+3
When one of the 3d is full, its storage container is discharged to the rear container stack;
The empty container 36 at the top drops to the bottom and is used as a storage container. The empty portion of the empty container 36 that has fallen downward from the empty container supply line 2 is filled by the empty container 36 on the right side thereof being shifted by the empty container feeding mechanism 35. As a result, the rightmost empty container 36 adjacent to the empty container supply section 37 becomes vacant, and the next empty container 36 is supplied from the empty container supply section 37 to this vacant section.

An example of such a supply system is shown in FIG. FIG. 3A shows a state in which the container at the storage container 33b is full and an empty container 36 is supplied. The dotted line indicates the position where there is no empty container 36. Next, the two empty containers 36 in the positions of the storage containers 33c and 33d are shifted to the left by the distance between the storage containers, resulting in a state as shown in FIG. Shift to the right and storage container 3
3d becomes empty (dotted line area).

Therefore, the empty container 36 is supplied from the empty container supply section 37 to this empty space. In this way, the empty container 36 can be placed in a standby state at each storage container position by shifting by the distance between the storage containers. The empty container supply section 37 simply supplies the empty container 36 to the one on the right side.
All you need to do is supply.

Therefore, only one common empty container transport line is required, and the operation of supplying empty containers 36 can be performed efficiently and in a short time.

Here, the relationship between the empty container 36 and the floppy disk accumulation section, and between the storage container and the container accumulation section is as follows:
This is due to the relationship shown in Figure 3.

The floppy disk 2 dropped by the falling push-out mechanism 31c is received by the packet 5 of the push-out mechanism 31c and is deposited there. A predetermined amount of the floppy disks 2 are pushed out by the cylinder 4 to the negative part of the stacking section 7, including the packets 5. Note that each floppy disk accumulation section 32a, 32b, 3
2 c, 32 d are represented here by the integrated deposition part 7
It will be explained as follows. In addition, three packets 5 are arranged in parallel corresponding to the three accumulation storage sections, and the third packet shown in the side view is
In the figure, only one of them appears.

The bottom of the packet 5 is open, and the opening/closing cylinder 6 that opens and closes the bottom part of the packet 5 is placed in a position where it does not interfere with the falling of the floppy disk 2 from above. It is provided. Therefore, when the packet 5 is located at the upper part of the stacking section 7, the opening/closing cylinder 6 is activated to open the bottom of the packet 5 and drop the stacked floppy disk 2 into the -4 part of the stacking storage section 7.

Here, as shown in FIG. 3, the accumulating and stacking section 7 is composed of two holding frames 8 and 9 arranged in front and behind and an elevator mechanism 10, and the holding frames 8 and 9 are
It is arranged on the front side of the storage container 33. An elevator mechanism 10 is provided between the presser frames 8 and 9, and a stacking table 11 of the elevator mechanism 10 can be moved up and down between the presser frames 8 and 9. Note that the storage container 33 is different from each storage container 3.
3a, 33b, 33c, and 33d are representative.

The two holding frames 8 and 9 are positioned so that the distance between them is slightly larger than the front and rear width of the floppy disk 2.
It is connected to the arm 12a of the robot, is supported vertically, and moves back and forth. The presser frame 9 is connected to the cylinder 13 via an arm 13a, is similarly supported vertically, and moves back and forth. The arm 13a of the cylinder 13 passes through a vertically elongated back opening provided at the back of the storage container 33 whose height is slightly smaller than that, and the presser frame 9 moves in and out of this back opening as the holding frame 9 moves forward and backward.

The lengths of these holding frames 8 and 9 are approximately equal to the height at which the floppy disks 2 are piled up.
has a length that fits into the floppy disk storage section of the storage container 33 and comes out from the rear opening.

Note that the storage container 33 has three storage blocks partitioned from each other, and three back openings and holding frames 8 and 9 are arranged in parallel corresponding to these three storage blocks. Only one of them appears in .

Here, the elevator mechanism 10 of the accumulating and depositing section 7 has a configuration in which the stacking table 11 is arranged between two presser frames 8 and 9, and this elevator mechanism 10 is operated by the actuator 4 of the extrusion mechanism. The floppy disks 2 are piled up so that the level difference between the bottom of the pile of extruded floppy disks 2 and the top surface of the floppy disks 2 at the top of the stack of floppy disks 2 already deposited on the stacking table 11 corresponds to the amount of floppy disks 2 deposited at one time. It is controlled to position the platform 11.

In this case, the positioning of the stacking table 11 is determined by the height of the floppy disks 2 stacked on the packet 5. That is, first, the -L side of the deposition table 11 is located near the top of the two holding frames 8 and 9 (a position slightly lower than the top and corresponding to approximately one deposition amount). It is set as follows. Then, every time a floppy disk 2 is deposited by - times of extrusion and falling, the height of the floppy disk 2 deposited on the packet 5 is (-
(according to the amount deposited).

Here, the storage container 33 is installed on the base 14, and the empty container 36 placed at the -L section falls to the position indicated by the dashed line behind the container 33 by the release operation of the locking mechanism 15, and the empty container 36 is placed on the base 14. It is pushed out to the front by the push-out mechanism 16 and set at the position shown in FIG.

Note that 15a is a holding plate that holds the empty container 36 from the back side, and 17a is a container extrusion cylinder 1.
7 extrusion arm. Also, 16 al 16 b
are guide arms arranged above and below, and 16c is a sleeve guide member.

The container pushing mechanism 16 is fixed to the base 14, and the base 14 is supported by the rotation shaft 19 so as to be rotatable about the rotation shaft 19 in the direction of the conveyor 20 by a rotation drive mechanism (not shown). ing.

Now, when the empty container 36 is set from the position indicated by the dashed line to the position indicated by the solid line shown in FIG. It is positioned in front of the At this time, an integrated stacking portion 7 is formed between the presser frame 8 and the holding frame 8 .

Then, the floppy disks 2 are deposited on the stacking table 11 of the accumulating and stacking unit 7, and when a predetermined amount is reached, the upper surface of the stacking table 11 matches the lower storage surface of the storage container 33, and the lower end of the holding frame 8 located below. It should be noted that FIG. 3 shows the previous floppy disk stacking state.

When the predetermined amount is deposited, the cylinder 12 is driven forward and the stacked floppy disks 2 are pressed against the holding frame 9 by the holding frame 8, and the floppy disks 2 stacked on the stacking table 11 are further moved into the storage container. It is pushed out to the 33 side. Then, the presser frame 8 is further driven forward, and the presser frame 9
is driven backward, the storage of the accumulated floppy disks 2 is guided by a partition member that partitions the storage block, and the floppy disks 2 are accurately and tightly set in the storage position of the storage container 33. Note that, at this time, the forward/backward force relationship between the cylinders 12 and 13 is such that the cylinder 12 is larger.

When the floppy disks 2 are stored in the stacked state in the storage container 33 in this way, the holding frame 9 moves further back from the rear opening of the storage container 33, leaving the stored floppy disks 2 behind. It escapes to the outside of the back of the storage container 33. On the other hand, the holding frame 8 side is driven backward by the cylinder 12 and returns to its original position.

Thereafter, the storage container 33 containing the floppy disk 2 is rotated by the base 14 rotating 90 degrees around the rotating shaft 19 and sent to the conveyor 20 side. As the base 14 rotates, the container ejecting mechanism 1
6 rotates at the same time.

During this rotation or at the position located at the 42nd section of the conveyor 20, the container extrusion cylinder 17 of the container extrusion mechanism 16 is driven backward, and its extrusion arm 17a retreats, as shown by the dashed line. , the storage container 33 containing the floppy disk 2 is lowered and placed on the belt of the conveyor 20.

At this time, the storage side of the storage container 33 is oriented "-", and the floppy disk 2 stored therein is reliably stored due to its own weight and does not fly out.

Next, the conveyor 20 moves the storage container 33 to the right side in the drawing, and the storage container 33 located on the bell l- is conveyed to the container accumulation and stacking section 34. Then, it is pushed up by the cylinder elevator mechanism 21 and deposited sequentially from the bottom. Note that the container stacking and stacking section 34 has a space at the bottom into which one container can be inserted, and a locking mechanism (not shown) that holds some of the containers holds all the stacked containers. has been done. Moreover, this container accumulation and accumulation section 34 is a container accumulation and accumulation section 34 a + 3
4b, 34c, and 34d are representative.

On the other hand, during the υI-out operation of the storage container, the base 14 rotates back to the original position shown by the solid line. Thereafter, the empty container 36 falls from - to the position indicated by the dashed line and is pushed forward by the container pushing mechanism 16.
It is supplied as a storage container 33.

The empty container supply section 37 that supplies empty containers has the same configuration as the container accumulation and stacking section 34 described above, but is oriented in the conveying direction of the conveyor 20 or in the opposite direction. Therefore,
With this container volume part 34, the empty container supply part 3
7 will be explained.

In the empty container supply section 37, empty containers 36 are stacked at the positions where the storage containers 33 are stacked. The lowest empty container 36 of the empty containers 36 accumulated on the right side of the conveyor 20 is the cylinder elevator mechanism 21.
It descends and is dropped onto the belt of the conveyor 20, moves from right to left in the drawing, and stops when it hits the base 14 which is rotated 90 degrees.

The base 14 is in this state when the container ejecting mechanism 16,! −
Both rotate to lift the empty container 36 and rotate it from the state shown by the dashed line to the state shown by the solid line, so that it stands upright. FIG. 1 shows this state. Furthermore, the empty container 36 is pushed forward by the container push-out mechanism 16, and each storage container 33a, 33b,
Move forward to the surface position that coincides with 33 c and 33 d and line up with them.

The empty containers 36 placed in this line are carried by the elevator machine +M37a to the pick amplifier position (a position slightly higher than the height of one container) of the empty container feeding mechanism 35 arranged along the empty container supply line.
The hook of the handling mechanism 40 shown in FIG. 4(a) is held by the claw 41, and the hook of the handling mechanism 40 shown in FIG. 4(a) is lifted off.
The empty container is shifted on the empty container feeding mechanism 35 shown in FIG.

To explain the moving state of this empty container 36, the hook 41 of the handling mechanism 40 is L-shaped with the tip of the claw protruding forward from the bottom, and rotates around a shaft 43 at the top. Possibly supported. The shaft 43 is the moving base 4
It is fixed to a bracket 49 fixed to 8. The driving cylinder 42 has the tip of its rod pivotally connected to a hook 41, and is rotatably fixed to the lower side of the movable table 48.

Therefore, when the drive cylinder 42 advances and retreats, the catch is caused by the claw 4.
1 advances and retreats. The moving table 48 has two guide shafts 44.4.

Move 8 or more slides.

As shown in FIG. 4(a), the empty container supply section 37
The empty container 36 placed upright on the base 14'' is
This hook is locked by the claw 41 and the elevator mechanism 37
The empty container feeding mechanism 35, . 33 al 33 b+ 33 c
, 33 d.

As shown in FIG. 4(b), four pairs of hooks 41 are provided at intervals corresponding to the intervals between the storage containers, and the four hooks 41 are as follows: They are each commonly fixed to the drive shaft 46. Therefore, cylinder 47
According to the drive of the drive shaft 46 by
41 is simultaneously shifted from right to left or from left to right via brackets 1-46a and 46b, moves by the distance, and returns to the original position. FIG. 4(b) shows a state in which the empty container 36 is shifted from right to left, and the empty containers 36 are the storage containers 33a and 33b.

33c and 33d, and at this time cylinder 47
is in a state of contraction. Then, when the cylinder 47 is expanded, each empty container 36 is replaced by each storage container 33b,
33c, 33d and the empty container supply section 37.

Here, when the four pairs of hooks 41 and 41 protrude, the empty container 36 is hooked and held slightly lifted, and the empty container 36 is moved along the empty container feeding mechanism 35 according to the drive of the cylinder 47. Shift along the container supply line.

On the other hand, when the claws 41 and 41 of the pair of hooks are retracted, the empty container 36 remains on the rack and remains in that position. In this placed position, it is held by the locking mechanism 15 as shown in FIG. Whether or not to shift while holding the empty container 36 in this way can be selected by whether the catch protrudes (or retracts) the claws 41,41.

Therefore, movement as explained in FIGS. 2(a) to 2(C) becomes possible. That is, in the state shown in (a) in FIG. 2, the pair of hooks corresponding to each storage container are connected to the claws 41.
After retracting the cylinder 41 and extending the cylinder 47, the pair of hooks corresponding to each storage container 33b, 33C are attached to the claws 41.
41 to the container side and contract the cylinder 47, the state shown in FIG. 47, each storage container 33d
The pair of hooks corresponding to the above will be in the state shown in FIG. 2(C) if the claws 41, 41 are projected toward the container side and the cylinder 35 is retracted.

As explained above, in the embodiment, the floppy disks discharged from the conveyance line are deposited in the -H bucket and then stored in the accumulation section. , 3 rows) and deposited in the accumulation section, and it is not necessary to use such packets. Therefore, the liquid may be directly dropped and discharged into the accumulation section without going through the packet.

In the embodiment, the hook is a shifting mechanism using a claw, but any mechanism for moving an empty container may be used. Furthermore, although the empty container replenishment line is placed above the storage container, it may be placed on the bottom or rear side as long as it is placed adjacent to it. Note that the arrangement must be such that it does not interfere with the evacuation of the storage container.

In the embodiment, a floppy disk housed in a case is used as an example, but the present invention can be similarly applied to a floppy disk housed in a jacket. This method can be generally applied to devices in which plate-shaped electronic articles are stacked and stored in a container.

[Effects of the Invention] As can be understood from the above explanation, in this invention, an empty container replenishment line is commonly placed adjacent to a row of storage containers arranged according to the measurement results, and the empty container replenishment line is An empty container supply unit is connected to one end of the line to supply empty containers, and the supplied empty containers are placed in a standby state corresponding to each position where storage containers are placed on the empty container supply line. By doing this, when a storage container is discharged, an empty container can be immediately supplied, and the position of the supplied empty container is
Since it is one of the positions arranged in a line, an empty container can be positioned corresponding to each storage container by simply feeding it in the feeding direction by the distance between the storage containers.

As a result, we can efficiently supply empty containers,
Furthermore, since only one empty container supply section is required, the space required for storing the plate-shaped electronic article in the container can be small.
