Description

[Detailed Description of the Invention] At present, especially printed wiring boards (hereinafter simply referred to as boards)
The mounting process of various electronic components such as chip type, Merck type capacitors, resistors, etc. to the base and the soldering process are performed in various processes such as the process of mounting various electronic components on the base (unprocessed, semi-processed, or When transferring finished products from the previous process to the next process, a dedicated rack (for 50 pieces,
(100 sheets for people, etc.) are often used.

This rank (hereinafter referred to as existing rack l) is generally configured in the shape of a box shelf as shown in the first diagram, and the bases B' are inserted and stored horizontally and parallelly on each shelf 2 at equal intervals. For example, this existing rack/is set in the substrate supply device S-H provided close to the conveyor ψ of the automatic chip mounting device 3 that mounts chips (capacitors, resistors, etc.) on the substrate. . The substrate supply device S is
For example, it consists of a mechanism that lowers (but still raises) the entire existing rack 1 to a certain size over a set period of time and a protruding arm 6, and each time the predetermined size descends, the protruding arm 6 protrudes and supplies one board B' to the top of the conveyor. do.

A substrate storage device 7 having the same configuration as the supply device S is also provided at the rear end of the conveyor ψ, and an empty viewing rack L is set on the device 7 to store the chip-mounted substrates B. ' is inserted into each shelf a one by one using an insertion arm and stored.

Existing racks 1 that have become empty due to supply are quickly replaced with new racks 1, and existing racks 1 that have been filled are quickly replaced with empty racks 1 and sent to the next process.

Conventionally, the above-described procedure has been used not only in the case of the above-mentioned chip mounting apparatus but also in cases where the substrate needs to be moved from various previous processes to the next process.

However, in the above, the replacement set of empty racks has become an unexpected drawback in terms of rack utilization.

In other words, the number of substrates stored in - existing racks is set to 50, for example.
In the case of a chip mount device, the substrate B' must be fed onto the conveyor l and stored every 8 seconds.
For 50 sheets, the total time is 400 seconds (6 minutes 40 seconds).

Therefore, it is necessary to replace the old and new racks on the device S every 6 minutes and 40 seconds. At that time, the ejection supply of the final board is completed → the empty hook is removed → the device S is raised (
It is very difficult to accurately set a new position within 8 seconds. However, since various devices such as automatic chip mounting equipment are all fully automatic, if the boards are not fed to the correct position at regular intervals, it will cause a serious problem. The device must be temporarily stopped. This is a fatal drawback for automatic equipment that performs continuous processes.

Therefore, as shown in the third figure, a plurality of existing ranks 1 are placed on the turret table 9 in advance, and when the supply and storage are completed, the turret table 9 is rotated to a certain angle and the conveyor t This avoids the disadvantage of temporarily stopping the various automatic devices mentioned above by performing the conversion set of the old and new ranks for the system in a short time. However, this turret table method requires the installation of tables that occupy a large space in front and behind the conveyor, and moreover, compared to the above-mentioned single device 5.7, this device has multiple individual devices installed in a turret. In addition to being installed on a table, it also required a mechanism to control and rotate the table itself, and it also required multiple spare racks at all times, creating major problems in terms of cost and installation space.

The present invention has been made in view of the above circumstances, and by installing the rank device of the present invention in close proximity to a conveyor, etc. in various automatic devices such as an automatic chip mount device, instead of the conventional method described above, it is possible to This small and compact device enables the continuous supply and storage of substrates, etc. in a continuous operation trench for various automatic devices.

That is, the present invention provides the following features: Bell) 10. A pair of supporting and moving bodies C and D are provided with supporting parts 13 at equal intervals on one side of a chain 11 or a plate-shaped body 12, etc., for supporting the end of a storage plate-shaped article B such as a printed wiring board B'. They are installed parallel to each other with a distance l corresponding to the size of the plate-shaped article B, and between the parallel parts, the supporting parts/3 of both supporting and movable bodies C and D face each other in a horizontal position, and both supporting and movable bodies are made to face each other in a horizontal position. The bodies C and D face each other parallel to each other, and the position of the support body 13 can be synchronously moved in the same direction by appropriate means, and this movement can be performed by intermittent movement of the support parts/, 71 dimensions, or by objective support. This is a ranking device A for plate-shaped articles such as a base B', which is selectively and movably provided for each section 13, and in the rack device A configured as described above, all the stored plate-shaped articles B are stored from an existing rack l. The rack device A is inserted into and placed on each support portion 13 of the device A, and the plate-shaped articles B are placed one by one by the sequential movement of the support portions 13 from the rack device A. This rack device A can be protruded and supplied to various devices, or can be supplied from various devices to this rack device A.
Similarly, by sequentially moving the support portion 13, the plate-shaped article B is
The present invention is characterized in that, at the same time as a fixed number of sheets are stored, all of the stored plate-like articles B are projected into the existing rack L and are all inserted and placed at the same time by means of an arm or the like.

In the above-mentioned rack device A of the present invention, the belt IO-shaped supporting and moving body is, for example, a sheet-like, flat-like, or net-like belt with a set length (e.g., a plate-shaped Item B length) with channel materials installed at equal intervals ((a) and (b) in Figure 6),
It is conceivable to form irregularities on the flexible belt itself to form support portions/3 ((c), 2), and (e) in FIG. 6).

In the case of a chain//, the belt is similar to that shown in Figure 6. For example, it is possible to attach the support portion 13 to each piece at appropriate intervals by tantimulating the support portion 13 at appropriate intervals. ).

The above-mentioned bell 1-10 chain // is usually formed endlessly by looping it around a sprocket, etc., as shown in the fourth diagram, but it is possible to use a belt lO or chain // of a certain length. It is also possible to use it as appropriate, for example, as shown in FIG.
It is also possible to move the support part 3 using the sprocket 17 or the like and then restore it all at once using a spring force.

In addition, a plate-shaped body (rigid or flexible) can also be used as the supporting and moving body CXD. For example, as shown in FIG. It is also possible to provide a rank tooth portion on the other side and move it by rotation of gear /9.

The supporting/moving bodies C and D each support one belt IO, etc. on the C and D sides, and one booby IJ -/! ; Also, as shown in Fig. 5, two belts 10,
10' around pulleys ts and ts', and belt 1
The same applies to the case where the support portion 13 is attached across the 01707.

In short, the present invention provides a supporting/moving body in which supporting portions are provided at equal intervals on one side of a belt, chain, or plate-shaped body, and the moving body is installed in a parallel state, and both sides of the parallel body are provided. This is because each support part of the moving body is made to face each other in a horizontal position.

The parallel installation dimension of this supporting/moving body C1D is determined to be commensurate with the dimension of the plate-shaped article B (at least slightly wider).

Therefore, it is desirable that the dimension l can be freely adjusted in width or narrowness according to the plate-shaped article B, and this adjustment can be done, for example, by adjusting or moving one of the supporting and moving bodies (C or D) in the horizontal direction. This is possible by configuring it appropriately.

The plate-like article rack apparatus A of the present invention configured as described above is as follows:
For example, as shown in FIG.
In the front rack device A, all the storage boards B' (for example, 50 boards) are pushed out from the existing rack l, and all the storage boards B' (for example, 50 boards) are removed by an arm or the like.
They are all pushed into the main storage device A and stored at the same time. At that time, each base B' is connected to each support part 13.1 of the supporting and moving bodies C and D.
Insert the left and right end portions into 3 to support it. This work is 1
Completes in less than seconds.

Next, the substrate B' stored in the rack device A is moved to a fixed position by the setting movement of the supporting and moving body CXD, and is fed upward onto the single-sheet conveyor using the conventional protruding pool 6 or the like. do. Then, while moving on the conveyor ψ, it goes through processes such as chip mounting and drying or UV irradiation of UV ink, and then reaches the rear of the conveyor.
The board B' is inserted into the single-sheet book rack apparatus A by inserting an arm similar to the conventional method, and is placed on each support part /3, /3 in synchronization with the movement of its supporting/moving body C1D. Storage in this rank device A is constant (for example, 5
When the number of storage boards reaches 0, all the storage boards in the main unloading device A are transferred at once into the existing rack using a protruding arm or the like as described above. Similar to the above, this task also takes less than 1 second.

Empty existing racks are returned to prepare new racks, and existing ranks containing processed boards are sent to the next process.

Note that, depending on the process, this rack device may be provided only at either the start side or the road side of the process.

As mentioned above, the plate-shaped article racking device of the present invention can be configured to be extremely small and compact, and this device itself is similar to the entire device that replaces a conventional existing rack and moves the entire rack up and down. It is equipped with an intermittent feeding or selective feeding function for plate-shaped articles, and in particular, it is possible to transfer all the stored plate-shaped articles from the existing rack at once and prepare for the next process, and the transfer operation is extremely easy. It is possible to provide a rank device that can supply and store plate-shaped articles (substrates), which has great effects in a short period of time, and can supply and store plate-shaped articles (substrates) without any fear of hindering the operation of various devices such as automatic chip mounting devices. It is something.

In the above description, the rank device of the present invention is mainly used as an example of a printed wiring board, and the manufacturing process of the board (chip mounting on the board) is mainly explained. printing process for
