Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically taking out or storing a file holder which can store a plurality of sheets, cards, documents such as medical charts.

[0002]

2. Description of the Related Art The applicant of the present invention previously found that Japanese Patent Publication No.
When storing and storing a large number of sheets and cards such as medical charts in hospitals in the publication, these cards are foldable file holders (there are gussets at the bottom, and the top and bottom of a pair of left and right cover covers). It is temporarily stored in the suspension type with the overhang reinforcement fixed, and this file holder is stored in the transport unit that moves along the front surface of the storage shelf unit in which many suspension rails are installed in parallel. We proposed a device that automatically stores or takes out a predetermined storage location in a shelf unit.

By the way, in the storage rack unit, a pair of left and right overhanging reinforcements on the upper portion of the file holder are inserted into the gap between the adjacent suspension rails arranged in parallel, and the lower surface of each overhanging reinforcement is the above-mentioned. It is designed to be placed on a suspension rail. However, when a large number of documents such as cards and sheets are stored in this type of file holder, the upper and lower midpoints of the pair of cover covers expand. Further, when the suspension rails are arranged at narrow intervals, even if there are not many contents such as documents in the file holder, the wide width of the cover cover of the adjacent file holders in the state where the suspension rails are arranged side by side The surfaces were in contact with each other, and it was difficult to push the file holder into the gap so as to store it.

In order to solve this problem, in the above-mentioned prior art, a pair of left and right insertion plates are provided at the front end of the transport unit as a moving block which moves back and forth so that the tip has a narrow left-right space and expands toward the base. The moving block is pushed out by the transfer table that is mounted, holds the upper part of the file holder and advances toward the storage location, and the tips of the pair of left and right insertion plates are laterally displaced from the side surfaces of the adjacent file holders. It proposes to secure the storage space of the file holder to be stored.

[0005]

However, according to the prior art, since the base portions of the pair of left and right insertion plates are fixed to the moving block, the thickness of the file holder to be extended is larger than the maximum one. The left and right spacings of the base portions of the pair of left and right insertion plates must be maintained, while the left and right spacings on the tip side of the insertion plates are narrower than the upper spacings of the suspended left and right file holders. The condition is that it is a thing. In addition, as a result of requiring a smooth curved surface from the tip to the base of the insertion plate so that the file holder passing between the inner surfaces thereof cannot be used, the length of the insertion plate becomes long. Therefore, the back-and-forth movement distance of the file holder is inevitably increased, the transport unit is increased in size, and the distance between the front face of the transport unit and the front face of the storage shelf unit must be increased. There was a problem that the whole became large.

The present invention has been made to solve this problem, and it is possible to smoothly store a file holder from a transfer unit between a plurality of file holders that are already suspended in parallel in a storage rack unit. It is an object of the present invention to provide a file holder extracting / storing device that can be used but has little wasted space.

[0007]

In order to achieve the above object, the present invention relates to a transport unit that moves along a front surface of a storage rack unit with respect to a suspended position arranged in parallel with the storage rack unit. In a file holder automatic take-out and storage device configured to take a file holder in and out through an entrance / exit, a nipping and conveying means for nipping an upper part of one file holder is provided in the conveyance unit, and the entrance / exit and the suspension in the conveyance unit. Restoration guide means including a pair of left and right insertion plates, which are provided so as to move back and forth with respect to a hanging point, and which are biased by rotation so that the distance between the tips is narrowed, is provided at the entrance / exit of the carrying unit, and the nipping and carrying operation is performed. When the file holder is unwound from the position facing the doorway to the suspended position by the means, the holding and conveying means concerned restores the file holder. The de means is advanced dynamic towards Tsukaka portion, which is constituted to push the inner spacing of the pair of left and right insertion plates in and feeding out file folder.

Touch and push forward. The guide roller 48 of the latch lever 46 is attached to the chevron guide block 60 fixed to the inner surface of the case 17 or the guide rail 50.
When is pushed, the latch lever 46 rotates upward about the horizontal shaft 45 and the engagement between the pressing roller 47 and the locking block 59 is released, so that the insertion plates 21 and 21 have moved forward by the distance L1. After that, it is retracted by the force of the return spring 57 (see FIG. 16). When the holding and conveying means 18 is retracted, the pressing roller 47 of the latch lever 46 is locked by the locking block 59.
Since it is possible to ride on the front end surface having a high inclination toward the rear of the holding block 59, the holding claw body 39 can return to the standby position.

It should be noted that the file holder 2 is stretched at the position where the file holder 2 has been completely loaded into the storage box 19a or 19b in the case 17, that is, on the placement guide rail 26 as shown by the chain double-dashed line in FIG. At the position where the reinforcing member 6 is placed and the holding claws 39, 39 are opened (see the alternate long and short dash line in FIG. 10), the pressing roller 47 may be positioned before the ride on the locking block 59.

Next, the thickness detecting means 61 for detecting the thickness of the file holder 2 will be described with reference to FIGS. 7 and 17 to 20. The thickness detecting means 61 in this embodiment is arranged in the space between the pair of left and right insertion plates 21 and 21 and the storage boxes 19a and 19b in the restore guide means 20, and has a pair of left and right vertical axes 62,
When the file holder 2 is taken into the storage box direction from the hanging position by the vertically-long sensor bodies 63a and 63b mounted integrally with 62 so as to be rotatable left and right, and the conveyance holding means 18, the left and right cover covers of this file holder 2 A rotary encoder 64 for detecting the rotation angle of one or both of the two sensor bodies 63a, 63b which rotate by contacting with 2a, 2b. Rotary encoder 64
The left and right cover covers 2 of the file holder 2 from the detected values of
The thickness of the thickest portion of the distance between a and 2b is converted and detected.

In this embodiment, the left and right sensor bodies 63a, 63a are made different in that the file holders 2 come into contact with each other at different degrees.
Even if the turning angles of b are different, the thickness of the file holder 2 can be accurately detected from the sum of the turning angles. Therefore, as shown in FIG. 17, the vertical axis 62 to which the one sensor body 63b is attached is the case 1
It is rotatably supported by a support bracket 65 fixed to 7, and a link plate 66 adapted to rotate integrally with the sensor body 63a is attached to the lower end of the vertical axis 62. The link plate 66 is provided with a rack 67 and left and right longitudinal guide grooves 68. The vertical axis 62 that rotates integrally with the other sensor body 63a is rotatably fitted into the pair of upper and lower support bracket plates 69, 69. Installed on. The base of the connecting body 70 is attached to a support bracket 73 via a pin shaft 72 with a return spring 71 so as to be rotatable left and right, and the support bracket 73 is fixed to the case 17. The first gear 74 that rotates integrally with the vertical axis 62 is the second gear 75 that is rotatably supported by the upper support bracket plate 69.
The third gear 76 is rotated via. This third gear 76
A rotary encoder 64 is attached to the. The fourth gear 77 mounted to rotate integrally with the lower end of the vertical axis 62 is a rack 67 on the link plate 66.
It is arranged so as to mesh with. And the vertical axis 6
The lower end of 2 is fitted into a guide groove 68 in the link plate 66 and cannot be removed.

The support bracket plate 69 and the connecting body 70
The support bracket 73 is located in the passage hole 78 formed on the base side of one of the insertion plates 21, and is configured not to interfere with each other when the insertion plate 21 rotates. With the above configuration, as shown in FIG.
With the left and right thicknesses (dimension H1) of the file holder 2 taken in the direction, both the left and right sensor bodies 63a, 63b are E,
Rotate in the E'direction. The link plate 66 is rotated by the rotation of the right sensor body 63b, but since the lower end of the vertical axis 62 of the left sensor body 63a is fitted in the guide groove 68, it is linked to the fourth gear 77 on the vertical axis 62. The engagement of the plate 66 with the rack 67 does not come off. Therefore, the right sensor body 6
The third gear 77 rotates due to the rotation of 3b and / or the rotation of the left sensor body 63a itself, and the rotation angle is the vertical axis 62,
Since it is transmitted to the third gear 76 via the first gear 74 and the second gear 75, this rotation angle is determined by the rotary encoder 64.
It can be read at. In this way, since the rotary encoder 64 can detect the total amount of the rotation angle of the right sensor body 63b and the rotation angle of the left sensor body 63a, the file holder 2 for both the left and right sensor bodies 63a, 63b can be detected. Even if the contact (contact) is uneven, the thickness can be accurately detected. As another embodiment, the rotary encoders 64, 64 may be attached to the respective sensor bodies 63a, 63b, and the detection values of the both may be added to accurately detect the thickness of the file holder 2.

The thickness of the file holder 2 is detected in the loading / unloading section 13 from the carriage 12 to the transport unit 3.
It may be executed only when the file holder 2 is moved in the direction. Even when the file holder 2 is discharged from the storage boxes 19a and 19b to the outside, the left and right sensor bodies 63a and 63b are also provided.
Rotates in the F and F'directions, but in this discharge mode (feeding mode), the detection value may not be output or the detection value data may not be stored.
When the file holder 2 is taken out from the storage rack unit 1, the thickness of the file holder 2 may be checked to facilitate the setting of the storage interval in the carriage 12.

Further, as shown in FIG. 19, the contact rollers 80 provided at the bases of the left and right insertion plates 21, 21 are pressed by the sensor bodies 63a, 63b which rotate in the directions of arrows F, F '. Or when the file holder 2 is extended without using the sensor body as a medium, the left and right insertion plates 21,
By directly contacting the inner side surface of the base side of 21 with the end of the file holder 2, the left and right insertion plates 21 and 21 are opened and rotated around the pivot 53, so that the file holder 2 can be stored in the storage box 19a. When discharged from 19b to the outside, the space between the inner surfaces of the left and right insertion plates 21 and 21 facing each other widens, and the contact resistance with the left and right outer surfaces of the file holder 2 pushed out by the sandwiching and conveying means 18 disappears (or decreases). Therefore, smooth discharge (feeding) is possible.

Next, the file holder 2 is loaded (transferred) from the carriage 12 in the loading / unloading section 13 to the transport unit 3.
The operation procedure will be described. As a preparatory step, the sandwiching and conveying means 18 in the conveying unit 3 is stopped at a standby position (behind the storage box), and the lateral movement motor 23 is operated to move the empty storage boxes 19a and 19b to the arrow D. ARA
And the storage box 19a farther from the bar code reader 29 is set so as to be located between the sensor bodies 63a and 63b.

A file holder presence / absence sensor provided on the case 17 of the transport unit 3 is caused by moving the transport unit 3 positioned in front of the carriage 12 in the loading / unloading section 13 in the direction parallel to the suspended file holder 2. The presence / absence of the file holder 2 is detected at 81, and the transport unit 3 is placed in front of the file holder 2 at a position such that the left and right insertion plates 21 and 21 at the entrance of the transport unit 3 sandwich the file holder 2 on the left and right sides. Stop.

Then, in this state, when the sandwiching and conveying means 18 is advanced in the direction of the entrance and exit (the direction of arrow A), the locking block 59 at the rear end of the movable beam 51 in the restore guide means 20.
Is pushed out by the pressing roller 47 of the latch lever 46, so that the insertion plates 2 and 21 are inserted into both left and right sides of the file holder 2 in the suspension position. The sandwiching and conveying means 18 advances as it is in the direction of the arrow A, and the sandwiching claws 39, 39 in the open state in the main body block 18a move to the file holder 2.
When it comes to the engaging hole 7 in the main body block 18a
And the electromagnetic solenoid 42 is actuated to close both clamping claws 39, 39. On the other hand, when the guide roller 48 of the latch lever 46 rides on the chevron guide block 60, the pressing roller 47 and the locking block 59 are disengaged, and the restoring guide means 2 is actuated by the restoring spring 49.
0 retreats.

Then, the body block 18a is retracted in the direction of arrow B. The sandwiched file holder 2 is brought into contact with both the left and right sensor bodies 63a, 63b and rotated as shown in FIG. 20, whereby the thickness of the file holder 2 is detected. Further, while the file holder 2 is retracted, the bar code reader 29 reads and detects the bar code to identify the file holder 2 in the storage box 19a. When the overhanging reinforcement body 6 at the upper end of the file holder 2 is completely placed on the placement guide rail 26 on the storage box 19a, the holding claws 39,
39 is opened, and the main body block 18a is once retracted to the standby position. Next, the lateral movement motor 23 is operated to move the storage boxes 19a and 19b in the direction of arrow C, and the storage box 1
9b is set so as to face the doorway, and another file holder 2 is placed in the other storage box 19b by the same operation as described above.
Take in. This operation is executed in the same procedure when the file holder 2 is loaded from the storage rack unit 1 to the transport unit 3.

Next, an operation procedure of storing (inserting) the file holder 2 between the transport unit 3 and the suspension rails 5, 5 of the storage rack unit 1 will be described. With the main body block 18a retracted to the standby position, the storage box 19b
Are set so as to face the doorway, then the main body block 18a is moved forward in the direction of the arrow A, and once stopped, both clamping claws 39, 39 are closed to engage with the engaging holes 7, and the main body block 18a is advanced. As a result,
As shown in FIG. 9, the end portions of the file holder 2 spread the space between the left and right sensor bodies 63a and 63b, and the contact rollers 80,
The space between the insertion plates 21 and 21 is slightly widened via 80. At this time, since the engaging block 59 is pushed by the latch lever 26 at substantially the same time, the tastor guide means 20 moves forward, and the left and right insertion plates 21 and 21 secure the right and left intervals of predetermined storage locations in the storage rack unit 1. Like Therefore, when the file holders 2 are already present on the suspension rails 5 and 5 adjacent to the storage location, the file holders 2 and 2 on the left and right sides are laterally displaced and stored (stored). This makes it easy to insert the proper file holder 2. Moreover, since the insertion plates 21 and 21 are opened and rotated according to the thickness of the file holder 2, the required length can be shortened as compared with the insertion plates 21 and 21 in which the left and right sides on the base side are fixed, and the transport unit 3 can be made compact.

When the main body block 18 is stopped at the most advanced position, the file holder 2 is in a state of being suspended and supported by the suspension support rail bodies 5 and 5 in the storage rack unit 1, so that the holding claw bodies 39 and 39 are opened. The main body block 18a is retracted to the standby position. Then, the lateral movement motor 23 is operated to move the storage boxes 19a and 19b in the direction of arrow C, and the storage box 19a is set so as to face the entrance and exit, and the other storage box 19a is operated by the same operation as described above. Then, another file holder 2 is sent to. This operation is performed by the transport unit 3
The same procedure is performed when the file holder 2 is ejected from the carriage 12 to the carriage 12.

In the present invention, the restore guide means 2
The center of rotation of the left and right insertion plates 21 and 21 (pivot axis 53) at 0 may be arranged at the front portion of the storage box, but the farther it is from the entrance to the rear side, the more the opening rotation occurs. In the above, there is no abrupt change in the degree of variation in the left-right spacing on the base side and the variation in the left-right spacing on the tip side of the left and right insertion plates 21, 21. In that case, if the space between the tips of the left and right insertion plates 21 and 21 is formed in advance to be slightly smaller than the space between the left and right sides on the base side, only the space between the tips opens more than necessary during the opening and rotation. Since such an operation is not performed, it is not necessary to perform an operation with a large resistance that largely displaces the adjacent file holders in the lateral direction.

In addition, the work of sending or taking in the file holder is executed for one of the storage rack units 1 and 1 facing each other, and the same work is executed for the other storage rack unit 1 as well. The direction of the transport unit 3 may be changed by 180 degrees with respect to the column 11. Instead of the horizontally rotating structure of the transport unit 3, doors are formed on both front and rear sides of the case 17 of the transport unit 3, and restore guide means 20 and thickness detecting means 61 are provided symmetrically with respect to both doorways. The plurality of storage boxes are formed so that the front and back of each of them are opened, and the plurality of storage boxes are configured to be horizontally moved in the direction of arrow C or D at the same time by a horizontal moving means (not shown), and are shared. A pair of guide fixing claws 38 and a sandwiching claw body 39 and an electromagnetic solenoid 42 which is an operating mechanism thereof are provided in front of and behind the main body block 18a in the power-carrying and conveying means 18 to move the file holder into and out of each storage box. It may be configured so that it can be executed for.

In the above-described embodiment, the stacker crane 10 which moves along the front surface of the storage rack unit is provided with the transport unit 3 so as to move up and down. It may be configured to move laterally.

[0038]

As described above, according to the first aspect of the present invention, the transport unit that moves along the front surface of the storage rack unit with respect to the suspended position arranged in parallel with the storage rack unit. In a file holder automatic take-out and storage device configured to take a file holder in and out through an entrance and exit of the carrying unit, the carrying unit has a holding and carrying means for holding an upper portion of one file holder, Restoration guide means including a pair of left and right insertion plates, which are provided so as to move back and forth with respect to the suspended position and are urged to rotate so that the distance between the tips becomes narrow, is provided at the entrance and exit of the transport unit. When the file holder is unwound from the position facing the doorway to the suspended position by the transfer means, the holding guide means restores the file holder. Means advancing movement towards the Tsukaka position and from and configured to push the inner spacing of the pair of left and right insertion plates in and feeding out file folder,
The left and right insert plates can be opened depending on the thickness of the file holder to be extended. Therefore, even if the storage space is narrowed due to the file holders that are suspended adjacent to each other at the storage location, it is possible to eject the file holders by passing between the pair of left and right insertion plates in the restore guide means, and thus the adjacent file holders. When the file holder is unwound from the storage box to the suspended position, the storage gap of the file holder can be secured, and the file holder can be smoothly stored. .

The file holder can be discharged smoothly even if the front and rear lengths of the pair of insertion plates are shorter than those of the conventional one in which the left and right intervals on the base side are fixedly arranged. Therefore, the front-rear length of the transport unit can be shortened, and the distance from the front surface of the storage shelf unit can be shortened, so that a dead space can be eliminated in the entire apparatus.
