BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage box for temporarily storing a thin plate-shaped article such as a printed wiring board when the article is assembled and processed.

[0002]

2. Description of the Related Art Conventionally, in this type of storage box, those having a mechanism for adjusting a storage width are available on various markets.
In any case, a method is generally used in which the movable side plate is moved by applying an artificial force directly to the movable side plate for determining the storage width, and the storage width is adjusted. They must also secure the moving side plates so that the adjusted storage width does not shift during subsequent use. Therefore, a method using a specially mounted fixing mechanism, screw fastening mechanism, or the like is adopted.

[0003]

In the case of this type of storage box known in the art, the storage width is adjusted by direct manual operation on the movable side plate, so that even if there is no time, there is a large width adjustment. Can be performed relatively easily up to a position close to the target position, but it is very difficult to move precisely to the final target position and make fine adjustments. It will take time. In addition, since it is necessary to adjust the upper and lower four places, it is necessary to adjust the width step by step. Therefore, in the mechanism for labor saving of the printed wiring board etc. and the manufacturing equipment, time and spirit There is a problem that a burden is imposed physically and physically. The present invention has been made in view of such problems of the prior art, and performs the operation of adjusting the storage width simply, accurately, and quickly, and further performs the above-described moving side plate without performing any special operation and training. Is designed to be able to be fixed to a predetermined storage width, thereby reducing and removing a load from a person who performs the work.

[0004]

In order to achieve the above object, a storage box according to the present invention stores a plate-like article between a fixed side plate and a movable side plate facing each other, and moves the movable side plate. A storage box whose storage width can be adjusted by, arranged in parallel so as to define the moving direction of the moving side plate, and at each of an upper part and a lower part of the storage box, at least one pair of slide bars and A rotating shaft provided in parallel with the slide bar and having a thread on the outer periphery, and guided so as to be slidably fitted to the slide bar and translate in parallel, and screwed to the rotary shaft. A pair of upper and lower moving blocks each having a screw hole and supporting the moving side plate, a single driving sprocket that is located on the outer surface of the fixed side plate, and to which rotational power is externally applied, It comprises a driven sprocket attached respectively to the ends of the rotary shaft passing through, and a chain wound around between the driving sprocket and the driven sprocket to. Rotational motion applied to the driving sprocket from a manual rotary handle or an electric driving mechanism is transmitted to a driven sprocket of a rotating shaft via a chain such as a ladder chain, whereby a plurality of rotating shafts are moved in the same direction, Rotate at the same speed. Since the moving block is screwed to the rotating shaft, the moving block is horizontally moved while being guided by the slide bar to move in parallel. Since the movable side plate is supported by the upper and lower movable blocks, the movable side plate moves in conjunction with the horizontal movement of the movable block, and the storage width is changed. On the other hand, since the moving block and the rotating shaft are engaged with each other by the thread as described above, the moving block is stopped and the moving block is fixed at the same time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. First, in FIG. 1, when a rotary motion is applied to the ladder chain driving sprocket 8 attached to the central portion of the fixed side plate 4 using a manual rotary handle or an electric drive mechanism, the rotary motion passes through the ladder chain 18. The two ladder chain driven sprockets 6, 7 attached to the upper and lower central portions of the fixed side plate 4 have the same direction.
Give rotation at the same speed. At this time, the small sprockets 9 and 10 for the ladder chain function as tension rollers and guide rollers. As shown in FIG. 4, the ladder chain driven sprockets 6, 7 are fixed to one end of the rotating shaft 11, so that the rotating shaft 11 rotates in conjunction with the rotation of the ladder chain driven sprockets 6, 7. In FIG. 3, the surface excluding both ends of the rotating shaft 11 and the surface of the through-hole formed inside the moving block 14 are threaded, so that the rotating shaft 11 is in contact with the through-hole of the moving block 14. Since the two threads are engaged with each other, and both ends of the rotating shaft 11 are rotatably inserted into receiving holes formed in the fixed blocks 15 and 16, the moving block is rotated by the rotating motion of the rotating shaft 11. 14 moves on the rotating shaft 11. As shown in FIG. 2 to FIG. 4, the slide bars 12 and 13 have both ends formed in the moving block 14 penetrating through cylindrical through-holes facing the fixed blocks 15 and 16. Since both ends are inserted into the receiving holes formed in the fixed blocks 15 and 16, the moving block 14 can always be kept parallel to the fixed blocks 15 and 16 even while the moving block 14 is moving. It becomes possible. On the other hand, cylindrical projections are formed on the upper surface of the lower moving block 14 and the lower surface of the upper moving block 14, respectively.
Since this portion is inserted and fixed inside the moving side plate 19, the moving side plate 19 moves in conjunction with the horizontal movement of the moving block 14. Further, when the movement of the moving side plate 19 is stopped, the inside of the through hole of the rotating shaft 11 and the moving block 14 is engaged with the threads of the both as described above. 19 is in a fixed state. One reason that the ends of the rotating shaft 11 are not threaded as shown in FIG. 4 is that when manufacturing the storage box of the present invention, the positions of the two upper and lower moving blocks 14 of the storage box are determined. This is for initial setting to the same position on the rotating shaft 11 that penetrates each. That is, when performing the setting operation, first, the slide rods 12 and 13 and one end of the rotating shaft 11 are inserted into the receiving holes of the fixed block 16, respectively. Next, slide rods 12 and 13 and rotating shaft 11
The other end is passed through the through hole of the moving block 14, and after inserting each end into the receiving hole of the fixed block 15, the moving side plate 19 is fixed. Further, the ladder chain driven sprocket 7 is attached to the end of the rotating shaft 11 protruding from the outer surface of the fixed side plate 4 through the through hole of the fixed side plate 4, and the ladder chain 18 is set. At this time, since the thread of the rotating shaft 11 and the thread of the through hole of the moving block 14 do not mesh with each other, the moving block 14 does not operate even if the ladder chain driven sprocket 7 is rotated. Next, the moving side plate 1
When the driven sprocket 7 for the ladder chain is rotated while the screw 9 is pressed in the direction in which the thread of the rotating shaft 11 is cut, the first thread of the moving block 14 and the rotating shaft 1 are rotated.
1 and the first thread are simultaneously engaged with each other, so that the movable block 14 can be moved. Another reason that the both ends of the rotating shaft 11 are not threaded is that after moving the rotating shaft 11 and the first thread of the moving block 14 in the manner described above, the moving block 14 is kept moving. In this case, the screw is prevented from being collapsed due to the rotation of the rotating shaft 11 even after the moving block 14 reaches the fixed block 16. That is, in order to disengage the final thread of the rotating shaft 11 from the final thread of the moving block 14 at the same time that the moving block 14 reaches the fixed block 16, the thread is located at a certain distance from both ends of the rotating shaft 11. Not cut. It should be noted that the operations and positional relationships in the above description do not apply only to one set of parts used in the description, but also apply to another set of parts constituting the storage box. It is. As described above, one embodiment has been described with reference to the drawings. However, the present invention is not limited to the above embodiment, and various modifications may be made to the embodiment within the scope of the claims. Can be done. For example, if an electric servomotor is mounted on the ladder chain drive sprocket 8 and a passage confirmation and storage width adjustment sensor is mounted at the passage position of the storage object,
It is also possible to adjust the storage width of the storage box completely automatically and store the storage object. Further, in order to prevent dust and dirt from adhering to the rotating shaft and the slide bar, the driving unit according to the present invention may have a structure as shown in FIGS. 6, 7, and 8. That is, using the moving unit 21 as a moving block, the rotary shaft 11 and the slide rods 12 and 13 are passed through those through holes, the periphery thereof is surrounded by the guide rail 20, and the protruding portion of the moving unit 21 is placed on the upper surface of the guide rail 20. It is possible to use the dustproof felt 22 in a state where the dustproof felt 22 covers the groove formed so as to protrude.

[0006]

Since the present invention is configured as described above, it has the following effects. First, when adjusting the storage width of the storage box, a rotational motion can be applied to the driving sprocket at a reasonable rotational speed by using a removable rotary handle or a removable electric drive mechanism. . Therefore, it is also possible to grasp the moving state of the moving side plate. Second, since the relationship between the magnitude of the rotational motion and the moving speed of the moving side plate is always constant, the moving side plate can be moved at a high speed by applying a large force when performing a relatively large width adjustment. . On the other hand, when performing a small width adjustment, it is possible to move at a low speed by applying a small force. Third, since the first and second effects and no special work is required to fix the storage width after the storage width adjustment work, the work can be performed easily, accurately, and quickly. The mental and physical burden on the person performing the work can be reduced. Fourth, since the movement of the movable side plate is linked to the rotational movement of the driving sprocket on the fixed side plate, by electrically controlling the rotation,
It is also possible to automatically adjust the storage width.
