[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic file holder unloading device.

[0002]

2. Description of the Related Art An example of an apparatus for automatically retrieving a file holder stored in a storage shelf is disclosed in Japanese Patent Laid-Open No. Hei 10-87011.
No. 6,086,045. This type of apparatus is mainly used in the management of medical charts in hospitals and the like, and usually has a mode in which the charts, X-rays, etc. of one patient are collected and managed in one file holder. Large hospitals, such as general hospitals, often have a plurality of such devices because of the large number of patients.
As disclosed in Japanese Patent Application Laid-Open No. 11-111, a conveyance path such as a conveyor is provided at the front side of each apparatus, and the file holders discharged from each apparatus are conveyed through this conveyance path, and are collected and discharged collectively in an accumulation unit. Means to make it happen are also being taken. It is also known to provide a plurality of stacking units of this type in the transport path. According to this configuration, for example, each stacking unit is assigned to a medical department such as internal medicine, surgery, or pediatrics.

[0003]

However, all of the conventional stacking units have a structure in which the file holders are laid on top of each other with the file holders lying down.
According to this structure, (1) the lower file holder may be damaged by the weight of the upper file holder, or the casing may be deformed. (2) When the file holder is sent from the transport path in a substantially upright state, a space for switching from “standing” to “lying down” is required, and the stacking portion is enlarged by the space. (3) In the stacking structure, the posture becomes unstable and the file holder is easily collapsed, so that the number of stacked books is naturally limited, and therefore the number of file holders to be accumulated is reduced. (4) When taking out the file holder from the exit of the stacking unit, the worker must take out the file holder while paying attention so as not to disturb the lying file holder, which is not convenient. (5) Delivery command (request) based on management computer etc.
In the case where the file holders are sequentially ejected, the file holders with the youngest ejection command numbers are stacked at the bottom at the bottom, but the exit (opening of the housing) is placed at the lowest file holder. Since it is not formed so as to face, when the worker takes out the file holder from the exit, the operator takes out the file holder stacked first, and the order of the delivery instruction does not match the actual removal order. . There was such a problem.

The present invention has been made to solve such a problem, and when the file holder is taken out of the container, the file holder is prevented from being damaged, and the file holder can be easily taken out from the exit. It is an object of the present invention to provide an automatic retrieval apparatus for a file holder which can save space in the entire apparatus.

[0005]

Each of the shafts 32 is fixed to each axis 32 so as to be plane-symmetric with respect to an imaginary vertical plane extending in the front-rear direction through the center point between the two.

In this embodiment, the transfer means 24 is
An extruding mechanism 45 for extruding the file holder toward the suspension rail 22 is provided, and has a structure utilizing the rotation of the shaft 32. Reference numerals 46a and 46b denote pushing members constituting the pushing mechanism 45. The pushing members 46a and 46b are made of a plate material extending in the radial direction of the shaft 32. The pushing members 46a are paired up and down on the upper side of the shaft 32 with the holder mounting plate 44 as a boundary.
6b are fixedly provided on the shaft 32 as a pair of upper and lower parts below the shaft 32, respectively. The extruding member 46a is provided with the holder mounting plate 4
4 is pushed out toward the upper suspension rail 22, and the pushing member 46 b pushes the file holder, which is placed and held on the placement part 31 c formed at the lower end of the frame 31, into the lower suspension rail. It becomes a member that is pushed out toward the rail 22. Extruding member 4 between left and right shafts 32
The positional relationship between 6a or the pushing members 46b is
This is the same as the case of the holder mounting plate 44, and is fixed to each of the shafts 32 so as to pass through a center point between the shafts 32 and be plane-symmetric with respect to a virtual vertical plane along the front-rear direction. The pushing member 46a and the pushing member 46b are fixed to the shaft 32 so as to have a crossing angle of 90 degrees with each other in a plan view.

As described above, since the shafts 32 rotate in directions opposite to each other, the holder mounting plate 44 and the pushing members 46a and 46b on the left and right sides always face the virtual vertical plane regardless of the rotation angle of the shaft 32. Symmetrically located. Frame 31

The shaft 32 has disc-shaped dogs 48a and 48b each having a slit formed therein. The rotation angle of the shaft 32 is regulated by the sensor 49. Reference numeral 47 denotes an in-stock sensor that detects the presence or absence of a file holder in the second retrieval device unit 27.

The holder mounting plate 44, the pushing member 46a,
The operation of 46b will be described. First, FIG.
The left and right pushing members 46a are attached to the front portion 31 of the frame 31.
The holder mounting plates 44 are positioned so as to be in parallel with and opposite to each other and retracted from the front surface 31a, and each of the holder mounting plates 44 has one side protruding from the front surface 31a, and the pushing member 46b is directed forward. 3 shows a state in which it protrudes from the front surface portion 31a. When the file holder falls in this state, the file holder is moved to the front side 31 by the side of the holder.
a, and the bottom surface of the storage body Fa (FIG. 2) comes into contact with the holder mounting plate 44, so that the container Fa is placed and held on the holder mounting plate 44 in a standing state (standing state).
When the shaft 32 rotates 90 degrees in the opposite direction, the right and left extruding members 46a rotate so as to approach each other and protrude from the front part 31a, as shown in FIG. Extruded toward the suspension rail 22 side. Since the left and right pushing members 46a push the file holder while rotating in the opposite directions, the leftward and rightward components of the individual pressing forces acting on the file holder are offset each other, and the right and left pushing members 46a are rotated in the same direction. The file holder can be transferred to the suspension rail 22 in a stable posture as compared with the case of extruding.

During this time, the holder mounting plate 44 rotates and always protrudes from the front surface 31a to hold and hold the file holder. In the state shown in FIG. FIG. 7 shows that the side was protruding.
In the state of (b), the other side protrudes instead. Further, in the state of FIG. 7B, the left and right push members 46b are positioned so as to be parallel to the front surface 31a and to face each other, and are retracted from the front surface 31a.

Next, the state of FIG. 7 (c) is a case where the shaft 32 is rotated 90 degrees in the opposite direction to that of FIG. 7 (b) from the state of FIG. 7 (a), and the pushing member 46a is moved backward. The pushing member 46b is positioned so as to be parallel to the front surface portion 31a and to be opposite to each other.
1a, the holder mounting plate 44 is also retracted from the front surface 31a. When the file holder drops in this state, the side surface of the file holder is supported by the front surface portion 31a, and is placed and held on the mounting portion 31c (FIG. 4A) of the frame 31 in an upright state. Will be. Then, by rotating the shaft 32 by 90 degrees so as to be in the state of FIG. 7A, the right and left pushing members 46b rotate so as to be close to each other, and the front portion 3
1a, the file holder of which is a lower suspension rail 2
It will be pushed out towards the two sides. Extruded member 4
Similarly to the case of FIG. 6a, the left and right pushing members 46b push the file holder while rotating in opposite directions to each other, so that the left and right components of the individual pressing forces acting on the file holder cancel each other out. The holder is transferred to the suspension rail in a stable posture.

A pair of upper and lower reference numerals 5 shown in FIG.
Numeral 0a denotes a light reflection type sensor for detecting whether or not a file holder exists on the holder mounting plate 44 and the mounting portion 31c, respectively, and is mounted in the frame 31 as shown in FIG. Reference numeral 50b denotes a reflector that reflects the light emitted from the sensor 50a that irradiates through the cutout of the frame 31, and is attached via a bracket to a side plate 56 that fixes the frame 31 at the side surface portion 31b.
The side plates 56 are provided in a pair on the right and left sides, and are members that close the left and right portions of the first retrieval device unit 26 and the second retrieval device unit 27, and extend to the exit port 15.

As can be seen from the above description of the operation, the holder mounting plate 44 constituting the holding means 21 is configured to be movable (rotatable), and the file holder is mounted on the upper and lower holding means 21 (on the upper side, the holder mounting plate 21). On the lower side, the plate 44 itself also serves as a switching means 25 for selectively holding the plate 44 on one of the mounting portions 31c). According to this configuration, a simple structure is realized, so that an economical automatic unloading device can be constructed. Also, the transfer means 24
(Extruding members 46a, 46b) and switching means 25
Since the (holder mounting plate 44) is arranged on a single member (the shaft 32) and linked to each other, a simpler structure can be realized.

The holding means 21 is not limited to the mode of holding and holding, but may be of a hanging type. Further, the file holder does not necessarily need to be held in a completely vertical state, and even if the file holder is slightly inclined, it is included in the “standing state” according to the present invention. Further, the holding means 21 can be formed on a suspension rail 22. For example, the suspension rail 22 is configured to be movable in the front-rear direction, while the file holder is reduced so that the width of the storage body Fa in FIG. 2 is the same as the width of the lower edge Fc. The lower surface end Fd of the locking body Fb is
The structure is such that it protrudes from the left and right ends of a. Accordingly, if the suspension rail 22 is moved backward when the file holder falls, the storage body Fa passes through as it is, and the lower surface end Fd is locked to the rear end of the suspension rail 22. The file holder is temporarily held in a suspended state.

When the holding means 21 is formed on the suspension rail 22, the transfer means 24 is of course unnecessary. However, the structure for moving the suspension rail 22 has a problem that the mechanism becomes complicated. As in this embodiment, the holding means 21 is provided separately from the suspension rail 22 and the transfer means 24 is provided.
Is provided, the mechanism of the apparatus is simplified, and an economical automatic unloading apparatus can be constructed.

When the falling file holder is received by the holder mounting plate 44 or the mounting portion 31c as it is, the impact at the time of contact is increased, and a loud collision sound is generated.
In some cases, the file holder may be damaged. In such a case, a deceleration means for lowering the falling speed of the file holder is required, but the falling file holder has a thickness of 8 mm, 15 mm,
There is a problem that the weight varies depending on the amount of stored files, for example, 30 mm. The movable roller 51 shown in FIG. 3 is a member for dealing with the problem, and has a function of absorbing a difference in falling speed of the file holder due to a difference in thickness and weight of the file holder and uniformly reducing the speed.

As shown in FIG. 3, the movable roller 51 is disposed as a pair of upper and lower parts so as to face the front surface 31a of the frame 31, and the upper movable roller 51 is located near the upper end of the frame 31 and the lower movable roller Reference numeral 51 is located below the holder mounting plate 44. The upper movable roller 51 is for reducing the falling speed of the file holder placed on the holder placing plate 44, and the lower movable roller 51 is placed on the placing section 3.
This is for reducing the falling speed of the file holder to be placed on 1c. Referring also to FIG.
1 is a cylindrical shape in which a pair of shaft bodies 52 are rotatably mounted on a frame body 53 while being separated from each other in parallel, and a plurality of grooves are formed at both ends of each shaft body 52 along the circumferential direction. Roller 5
4 is fitted around the outer periphery of the roller 54, and the endless strip 55 made of a material having a large coefficient of friction, for example, synthetic rubber, is wound around the groove of the rollers 54 so as to have a tensile force. It has a structure. That is, the rollers 54 of the two shafts 52 are synchronously rotated in the same direction via the strips 55. The outer surface side of the strip 55 is mounted so as to slightly protrude from the groove and protrude from the peripheral surface of the roller 54.

Then, one shaft 52 is rotatably mounted on the left and right side plates 56, 56, and the other shaft 52 is positioned on the lower side, and a bracket 53a attached to the frame 53 is provided. By the tensile force of a tension spring 57 stretched between the first shaft body 52 and the side plate 56, the one shaft body 52 is positioned closer to the front surface portion 31a of the frame 31 than the one shaft body 52.
The gap between the other roller 54 and the front surface 31a of the frame 31 is smaller than the minimum thickness of the file holder (8 mm in the present embodiment). A pulley 52a is axially attached to one end of the one shaft body 52, as shown in FIG.
, Pulleys 52a of the upper and lower movable rollers 51
And a pulley 58 a and a guide roller 59 which are mounted on an output shaft of a drive motor 58 fixedly installed in the sorting and unloading section 10.
The timing belt 60 is wound around.

With the above configuration, when the output shaft of the drive motor 58 is rotated clockwise in FIG. 3, the movable roller 51 is rotated in the same direction as the roller 54 and the strip 55 of the two shaft members 52 are integrally formed. I do. When the file holder drops in this state, the side surface of the storage body Fa (FIG. 2) comes into contact with the strip 55, and the movable roller 51 is moved forward against the tensile force of the tension spring 57 by its own weight. To rotate it. That is, the file holder is sandwiched between the movable roller 51 and the front surface 31a of the frame 31 by the tensile force of the tension spring 57, and the falling speed is reduced accordingly.
Depending on the value of the tensile force of the tension spring 57, the file holder may fall as it is under its own weight after deceleration, even if the strip 55 is not rotating. However, in the present embodiment, since the strip 55 is rotated, The strip 55 plays a role of a transport conveyor, and the frictional force acts to transport the file holder downward, so that the file holder can be reliably dropped without being clogged.

If the movable member (movable roller 51) having an elastic body such as a tension spring is made to abut against the file holder to reduce the speed, the difference in thickness and weight of the file holder is reduced. Can be absorbed, and all file holders can be decelerated to a substantially uniform speed. Therefore, it is possible to realize an automatic unloading apparatus that stabilizes the unloading time for each file holder and is excellent in unloading efficiency without unevenness.

Reference numeral 61 shown in FIGS. 8 and 9 denotes a shutter for preventing a file holder mounted and held on the holder mounting plate 44 or the like from falling forward. You. Eccentric cams 62 are fixedly mounted on the pair of left and right shafts 32, respectively.
2, the first link member 63 is pivotally supported in a horizontal direction via a pin 65 by a bracket 64 fixed at one end to a center portion of the frame 31 in the left-right direction. The first link member 63 extends in the left-right direction, passes through the notch 56 a of the side plate 56, and the other end of the first link member 63 is located outside the side plate 56. One end of a second link member 66 is connected to the other end of the first link member 63 via a pin 67 so as to be swingable in the horizontal direction. The second link member 66 extends in the front direction, and the other end, which is the front end thereof, is
1 are connected rotatably in the horizontal direction.

As shown in FIG. 8, the shutter 61 is made of a plate member bent and formed in a "-" shape in plan view, and a base plate 61a on one side thereof has a side plate 56 as shown in FIG. A pair of upper and lower spring hinges 6 with one side attached to
