Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a stocker for flat objects that is applied to supply or discharge wiring boards and the like to automatic adjustment and inspection machines.

"Background Art and its Problems" In order to continuously supply or discharge wiring boards and the like to an automatic adjustment inspection machine, a stocker is used to stock the wiring boards. As a stocker,
Conventionally, a mechanism as shown in FIG. 1 has been used. In FIG. 1, reference numeral 1 indicates a stocker for storing a wiring board. A stocker 1 is mounted on a moving table 2, and the moving table 2 is moved up and down by a cylinder 3. 4 shows an automatic adjustment inspection machine that automatically adjusts and inspects wiring boards. 5 indicates an air cylinder, and the air cylinder 5 is the stocker 1.
This is for feeding the wiring board from the automatic adjustment inspection machine 4.

A plurality of wiring boards to be adjusted and inspected are stored in advance in the stocker 1, and the stocker 1 is moved upward in steps by the cylinder 3. At the same time, each wiring board is sequentially sent out from the stocker 1 into the automatic adjustment inspection machine 4 by the air cylinder 5, and predetermined adjustment and inspection are performed. After the adjustment inspection has been completed, the wiring board is transferred to another stocker 1' from the outlet formed on the opposite side of the insertion opening.
They are sequentially taken out by a take-out mechanism (not shown).

A wiring board 6 is housed in the stocker 1 shown in FIG. 1 as shown in FIG. 2. As shown in FIG. In other words, the wiring board 6 is stored horizontally so that both ends thereof are placed on the guide steps 7A and 7B provided on both sides of the stocker 1.

In the conventional stockcar shown in Figs. 1 and 2,
The wiring board 6 to which electrical parts such as ICs, coils, and capacitors, and mechanical parts such as switches are attached is supported and stored at both ends, making it easy to bend under its own weight. Therefore, the wiring board 6 is supported within the stocker 1 by relatively wide step portions 7A and 7B. As a result, electrical components and mechanical components cannot be attached to both ends of the wiring board 6, resulting in mechanical constraints on the effective area of the wiring board 6, the thickness of the wiring board 6, and the like.

Furthermore, in this conventional stocker 1, the wiring board 6 is stored horizontally as shown in FIG.
The automatic adjustment inspection machine 4 supplied from the stocker 1 also has a structure in which the wiring board 6 is inserted horizontally. For this reason, the width of the automatic adjustment inspection machine is required to be greater than the width of the wiring board 6, and therefore, the installation space is required to be wide.

Furthermore, when using this conventional stocker 1,
It is difficult to attach a delivery and intake mechanism to the stocker 1 itself due to its structure. Therefore, when automatically sending and importing,
It is necessary to separately provide a mechanism for taking in and taking out the knob and a conveyance mechanism. This makes the entire system large and expensive. In addition, when the wiring boards are manually supplied to the stocker 1, the work is performed in the vertical direction, resulting in a problem of poor workability.

``Purpose of the invention'' This invention is designed to reduce the installation space of the automatic adjustment inspection machine, and has a narrow transport width.
The object of the present invention is to provide a stocker that can accommodate wiring boards with a wide effective usable area, has a built-in mechanism for sending out or taking out wiring boards, and is easy to store.

"Summary of the invention" This invention consists of a lower guide having a belt rotatably installed in a groove on the bottom, an upper guide installed parallel to the lower guide, and a set of the upper guide and the lower guide. This is a stocker for flat objects that includes a frame that supports multiple rows and a feed drive unit that is provided below the frame and drives a belt.

The operation of one embodiment of this invention described above will be explained. First, one wiring board 30 is manually inserted between the groove 17 having a U-shaped cross section provided in the upper guide 15 and the member 18 having an L-shaped cross section and the plate member 19 of the lower guide 16 facing each other. are inserted one by one. Then, as the indexing motor 26 rotates, the plurality of wiring boards 30 are transported to a predetermined position close to the automatic adjustment inspection machine while being supported by the frame. Here, in the feeding drive section, the cylinder shaft 38 of the air cylinder 40 is raised, and the positioning pins 36A, 36B are moved to the first position of the lower guide positioning bushes 21A, 36B.
21B, and the timing belt drive gear 35 is meshed with the timing belt 20.

Next, the feed drive motor 31 rotates in the direction indicated by A in FIG. When the feed drive motor 31 rotates, the driving force of the feed drive motor 31 is transmitted to the driving side gear 32 attached to the motor shaft, and then to the driven side gear 33 via the timing belt 34. Further, since the timing belt driving gear 35 is coaxially fixed to the driven side gear 33, this driving force is also transmitted to the timing belt driving gear 35.

Since the timing belt driving gear 35 has already been engaged with the timing belt 20 by the cylinder shaft 38 of the air cylinder 40 rising, the timing belt driving gear 35
The driving force is transmitted to the timing belt 20.
That is, when the feed drive motor 31 rotates in the direction A, the timing belt 20 moves in the direction indicated by a in FIG. 3.

Since the wiring board 30 generates sufficient frictional force due to its own weight to be transported by the timing belt 20, the movement of the timing belt 20 in the direction a causes the wiring board 30 to move in the U-shaped cross section provided on the upper guide 15. The wiring board 30 in the first position inserted between the L-shaped cross-sectional member 18 and the plate member 19 of the lower guide 16 moves in the direction a, and the wiring board 30 automatically adjusts. Sent to inspection machine.

In this way, when the wiring board in the first position is fed out, the cylinder shaft 38 of the air cylinder 40 is lowered, the engagement between the positioning pins 36A, 36B and the positioning bushes 21A, 21B is released, and the timing The belt driving gear 35 and the timing belt 20 are disengaged.

Next, the index motor 26 rotates by a predetermined amount, and the wiring board at the second position is sent out in the same manner as described above, and the same operation is repeated thereafter.

"Application Example" This invention can be similarly applied to the transportation of other flat objects other than wiring boards.

``Effects of the invention'' According to this invention, the wiring board can be supported by a relatively shallow groove, which limits the effective area of the wiring board and makes it possible for the wiring board to withstand more than a specified load. It is possible to remove constraints such as Furthermore, since the wiring board is vertically supported by the stocker, the wiring board can be inserted vertically into the automatic adjustment inspection machine, and an automatic adjustment inspection machine that does not take up much installation space can be used. Also,
When supplying wiring boards to a stocker, they are inserted at the same height, which improves work efficiency. Furthermore,
Since the feeding mechanism is attached to the stocker itself, a special transfer device is not required, and a small and inexpensive system can be constructed.
