Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a storage rack for a printed circuit board or the like in which a storage width can be freely adjusted by moving a movable receiving plate.

[Conventional technology]

Conventionally, a storage rack shown in FIG. 7 has been known as a storage rack for this type of print substrate and the like, which will be described with reference to FIG.

That is, in the figure, 101 is a rectangular parallelepiped frame body provided with a top plate 102 and a bottom plate 103, 104 and 105 are fixed receiving plates and movable receiving plates which are erected in the frame body 101 so as to face each other, and 106. Reference numeral 107 denotes a lateral groove-shaped substrate receiving groove formed at a constant pitch on the inner surfaces of the fixed receiving plate 104 and the movable receiving plate 105, and 108 and 109 denote top plates 102 from the side of the movable receiving plate 105 toward the fixed receiving plate 104. And a pair of guide grooves formed on the bottom plate 103 on both sides, 110 are slide pieces fixed to the upper and lower end portions of the movable receiving plate 105 corresponding to the groove holes 108 and 109, 111
Are bolts and nuts for fastening the slide piece 110 to the top plate 102 and the bottom plate 103 along the groove holes 108 and 109, respectively. In addition, A indicates a printed circuit board.

In the storage rack configured as described above, the both side edges of the printed circuit board A are sequentially inserted into the corresponding substrate receiving grooves 106 and 107 of the fixed receiving plate 104 and the movable receiving plate 105 so that they can be placed and stored in multiple stages.
Then, when accommodating the pilint boards A having different sizes, loosen the bolts and nuts 111 and slide the slide pieces 110.
The movable receiving plate 104 is moved in the direction of the fixed receiving plate 105 while sliding the same to match the width of the printed circuit board A, and then the slide pieces 110 are fastened to the top plate 102 and the bottom plate 103 by bolts and nuts 111, respectively. is there.

[Problems to be solved by the invention]

By the way, in the above-mentioned conventional storage rack, while the movable receiving plate 105 can be moved to freely adjust the space between the fixed receiving plate 104 and the movable receiving plate 105, it is possible to sufficiently accommodate the storage of the pilit board A or the like having different dimensions. In order to move the movable backing plate 105, it is necessary to operate the bolts and nuts 111 one by one to move and fix the movable backing plate 105 to an appropriate position.
The moving operation was very troublesome and time-consuming, and was extremely inefficient.

[Means for solving problems]

This invention intends to solve the conventional problems all at once, and in order to make the movable receiving plate 5 movable, a pair of windings on both sides which can be synchronously driven through gear mechanisms 12 and 14 etc. in the frame body 1. The transmission mechanisms 11A, 11B, 13A, 13B are arranged so as to face each other vertically, and the upper and lower winding transmission mechanisms 11A, 11B, 13A, 13B
Each of them can be synchronously driven via a shaft 19, and a required lock device 20 is attached.

[Action]

By gently pressing the movable backing plate 5 in a predetermined moving direction, the upper and lower winding transmission mechanisms 11A, 11B, 13A, and 13B are interlocked and driven synchronously in the same direction to move the movable backing plate 5 at a predetermined position at a fixed pitch. Then, the storage width can be freely adjusted by fixing it to a predetermined position by the lock device 20 after moving it.

〔Example〕

An embodiment of the present invention shown in the drawings will be described below.

Reference numeral 1 is a rectangular parallelepiped frame body, 2.3 is a top plate and a bottom plate having a substantially U-shaped cross-section fixed to the upper and lower surfaces of the frame body 1, and 4.5 are vertically erected inside the frame body 1 so as to face each other. A fixed receiving plate with substrate receiving grooves 6 and 7 and a movable receiving plate are provided with a support frame 8 on the outer side of the movable receiving plate 5. 9 and 10 are a pair of upper guide rails and lower guide rails laid on both sides of the top plate 2 and the bottom plate 3 from the movable support plate 5 side toward the fixed support plate 4, and 11A and 11B are provided on the top plate 2. The chain transmission mechanisms 11A and 11B can be synchronously driven in the same direction via the gear mechanism 12 by a pair of chain transmission mechanisms on both sides. 13A and 13B are a pair of chain transmission mechanisms arranged on the bottom plate 3 on both sides, and the chain transmission mechanisms 13A and 13B can be synchronously driven in the same direction via a gear mechanism 14. Then, the upper and lower chain transmission mechanisms 11A, 11B, 13A, 1
3B is constructed by winding a chain 17 between a pair of sprockets / wheels 15 arranged on the fixed / movable receiving plates 4/5 side and a guide sprocket / wheel 16 arranged substantially in the center. ing. Reference numeral 18 is a connecting piece for connecting each chain 17 and the end portion of the support frame 8, and 19 is a sprocket wheel corresponding to each of the upper and lower chains for synchronously driving the upper and lower chain transmission mechanisms 11A, 11B, 13A and 13B. Shafts 20 connected to 15 are locking claws that are swingably disposed via springs 21 so as to lock the gear mechanism 12.

In the storage rack configured as described above, the board receiving grooves 6 of the fixed receiving plate 4 and the movable receiving plate 5 that correspond to both side edges of the printed circuit board A are provided.
・ Sequentially insert into 7 and store and store. Then, when the storage width is adjusted to store the printed circuit boards A having different sizes, the movable receiving plate 5 is lightly pressed in a predetermined direction. Then, the upper and lower chain transmission mechanisms 11A, 11B, 13A and 13B are interlocked via the gear mechanisms 12 and 14 and the shaft 19 to drive the movable support plate 5 along the guide rails 9 and 10 synchronously in the same direction. It can be moved to a predetermined position on the pitch. When the movable receiving plate 5 reaches a predetermined position, the pressing of the movable receiving plate 5 is stopped, and then the locking claw 20 is locked to the gear mechanism 12 to fix the movable receiving plate 5 to the predetermined position.

In the above embodiment, the chain transmission mechanism 11A, 11B, 13A, 13B is shown as a winding transmission mechanism, but a known winding transmission mechanism such as a belt transmission mechanism or a rope transmission mechanism may be adopted. Further, the gear mechanisms 12 and 14 are shown as those for synchronously driving the winding transmission mechanism, but the invention is not limited to this and a known pair such as a pair of friction wheels may be adopted. Is. Further, although the locking claw 20 is shown as the locking device, the locking device is not limited to this, and other known locking devices may be adopted, and the mounting position thereof is the upper and lower gear mechanisms 12, 14, etc. It may be attached to one side or only one side.

[Effect of device]

According to this invention, a pair of both-side winding transmission mechanisms 11A, 11B, 13A, which can be synchronously driven through the gear mechanisms 12, 14, etc., in the frame 1 to move the movable support plate 5 according to the above. 13B
Are vertically opposed to each other, and the upper and lower winding transmission mechanisms 11A, 11B, 13A and 13B can be synchronously driven through shafts 19, respectively, and a required lock device 20 is attached. Therefore, the movable backing plate 5 is lightly pressed in a desired moving direction, and the upper and lower winding transmission mechanisms 11A, 11B, 13A, and 13B are synchronously driven in synchronization with each other to move the moving backing plate 5 at a predetermined position at a fixed pitch. And then lock it to the gear mechanism 12 etc.
With an extremely simple operation to lock the
The storage width of the storage rack can be adjusted quickly, reliably, and simply.
