[Background of the idea]

A device as shown in FIGS. 1 and 2 is conceivable as a guide means for sorting electronic components sent by one carry-in rail to a plurality of track rails.

Figure 1 shows this device (hereinafter referred to as the prototype device)
The plan view of FIG. 2 is also a side view.

An electronic component 1, which is an object to be transported, is guided by one carry-in rail 2 and is sent from the left to the right in the figure. The proposed guiding device distributes this to eight track rails and guides them.

3A and 3B indicate track rails to be distributed, and track rails corresponding to 3C to 3G are omitted and the eighth track rail 8H is drawn. Therefore, the illustrated spacing dimension L ₇ is seven times the spacing dimension L ₁ .

In the side view (FIG. 2), eight track rails 3A, 3B to 3H overlap.

Receive the electronic components 1 guided by the carry-in rails 2 and transport them to the eight track rails 3.
In order to transfer to any of the track rails A to 3H, a sorting rail 4 is provided that moves in parallel in the vertical direction in the figure (that is, perpendicular to the conveying direction). The above-mentioned classification rail 4 is mounted on a slide block 5, and is guided by a slide shaft 6 so as to move in parallel in the vertical direction in the figure.

The slide block 5 is moved in the vertical direction in the figure by a pulse motor 7 via a drive pulley 8 and a drive belt 9. 10 is a guide pulley.

As described above, the classification rail 4 connected to the end point 2a of the carry-in rail 2 is moved laterally in parallel with respect to the transport direction, and connected to the starting points of the plurality of track rails 3A to 3H at the parallel moved position. According to this guiding device, the electronic component 1 is transferred from the transport rail 2 onto the classification rail 4, the classification rail 4 is moved in parallel to the side and connected to a desired track rail, and the electronic component 1 is transferred to the desired track rail. It can be delivered.

However, when classifying electronic components 1 as objects to be transported by the above-mentioned guide device, the electronic components 1
There are difficult technical problems regarding the drive means for feeding the material in the conveying direction.

(a) Connect the transport device to each track rail 3A.
If one is provided every ~3H, the same number of similar feeding devices as track rails (eight in the previous example) must be provided, making the overall configuration complex and increasing the manufacturing cost.

(b) If the above-mentioned feeding device is mounted on the slide block 5 and moved sideways (up and down in the figure) together with the sorting rail 4, only one feeding device is sufficient;
As this feeding device moves, a means of supplying energy (e.g. electric wires, air hoses, hydraulic hoses, etc.) to the drive source (e.g. electric motor, air motor, hydraulic cylinder, etc.) must follow, making the structure complex and easy to handle. Not.

(c) Furthermore, unless some kind of braking means is attached to the above-mentioned feeding device, the movement from the carry-in rail 2 to the sorting rail 4
There is a risk that the electronic components that have been replaced will go too far due to their inertia, pass the classification rail 4, enter an undesired truck rail, or fall off the classification rail 4.

[Purpose of invention]

The present invention has been developed in view of the above-mentioned circumstances, and can be applied to the above-mentioned prototype guide device, and can transfer electronic components, which are objects to be transported, from the classification rail to the track rail with a simple configuration. It is an object of the present invention to provide a claw-feed type sorting and conveying device that is free from the risk of parts falling over a sorting rail or of being misclassified.

[Summary of the idea]

In order to achieve the above object, the classification conveyance device of the present invention connects a classification rail to the end of the carry-in rail,
A plurality of track rails for selectively transporting objects are arranged in parallel with the classification rail, and the classification rail is moved in parallel in a lateral direction so as to selectively face the plurality of track rails. The sorting and conveying device is configured such that a feed bar is arranged perpendicularly to the conveyance direction and has a plurality of feed claws arranged in a row corresponding to the plurality of track rails, and drives the feed bar up and down. and a means for reciprocally driving the feed bar forward and backward in the conveying direction, and the feed claws arranged in line with the feed bar move the objects to be conveyed on the sorting rail by vertical and back-and-forth movement of the feed bar. A shutter plate is provided between the sorting rail and the track rail to move it in and out, and the movement of the shutter plate in and out is linked to the vertical movement of the feed bar. It is characterized by:

[Example of idea]

Next, one embodiment of the present invention will be described with reference to FIGS. 3 and 4.

In this embodiment, the present invention is applied to the guide device of the above-mentioned prototype, and a claw feeding means in the conveying direction is attached. The rail 2, track rails 3A to 3H, sorting rail 4, slide block 5, slide shaft 6, pulse motor 7, drive pulley 8, drive belt 9, and guide pulley 10 are the components described in the prototype.

Above the starting points of the plurality of track rails 3A to 3H, a feed bar 11 shown by a solid line in FIG. The feed bar 11 is configured to be able to move in parallel to the vicinity of the end, and feed pawls 12 are arranged in a row on this feed bar 11, and these feed pawls are connected to track rails 3A, 3B to 3H, respectively.
to face.

As mentioned above, in order to reciprocate the feed bar 11 in the conveying direction (horizontal direction in the figure), a pair of guide shafts 14 are horizontally and slidably supported by a pair of slide bearings 13. end)
A pair of springs 15 and a pair of air cylinders 16 are provided for attaching and supporting the feed bar 11 and urging the feed bar 11 to the right in the figure.

In order to further drive the feed bar 11 in the vertical direction (perpendicular to the plane of paper in FIG. 3, vertically in FIG. 4), an air cylinder 17 is used as shown in FIG.
A moving base 18 is provided which is driven up and down by
9 supports the slide bearing 13 mentioned above. 2
0 is a guide block of the guide column 19, and 21 is a support thereof.

With the above configuration, the guide shaft 14 is
The guide shaft 1 is driven vertically and horizontally in the figure.
The feed bar 11 supported by the feed bar 11 and the feed pawls 12 arranged in rows on the feed bar 11 are indicated by the arrows A, B, C,
It is driven in a rectangular trajectory as shown in d. By this operation, the electronic components 1 shown in FIG.
Any one of H) is pushed and transferred.

The movement of the feed pawl 12 described above is based on the movement of the guide shaft 1.
Feedback is provided by detecting the movement of the light shielding plate 22 attached to the rear end of the light shielding plate 22 through the sensors 23 and 24. 25 is a sensor bracket, and 26 is its support.

As shown in FIG. 4, a shutter plate 27 is provided corresponding to the gap between the classification rail 4 and the track rails 3A to 3H, and is fixed to the movable base 18. As a result, when the feed claw 12 rises, the shutter plate 27 also rises, blocking the conveyance path between the sorting rail and the track rail, and causing the feed claw 12 to rise.
The transport path is opened when the transport path is lowered.

The electronic components 1 are transferred to each of the track rails 3A to 3 using the feed claw type classification and conveyance device configured as described above.
The operation of distributing to H will be described next.

When the electronic component 1 is pushed by a pushing means provided on the left side (not shown) and sent from the carry-in rail 2 to the classification rail 4, the pulse motor 7 shown in FIG. 3 moves the classification rail 4 as shown in the figure. Move it up and down and connect it to the end point of the carry-in rail 2 as shown in the figure. At this time, the air cylinder 17 shown in FIG. 4 is extended to raise the feed pawl 12 so as not to interfere with the electronic component 1 on the rail.

As the air cylinder 17 expands, the shutter plate 2
7 rises and blocks the end point of the sorting rail 4, so there is no risk that the electronic components sent onto the sorting rail 4 will go too far and enter a track rail other than the desired one or fall from the sorting rail. The pulse motor 7 is operated to connect the classification rail 4 carrying the electronic component 1 to a desired track rail (any one of 3A to 3H).

After extending the air cylinder 16 shown in FIG. 3 and advancing the feed bar 11 to the position 11' indicated by the imaginary line,
When the air cylinder 17 shown in FIG. 4 is contracted, the feed claw 12 descends to the rear of the electronic component 1 (to the left in the figure) as indicated by the imaginary line 12'.

With the above operation, the shutter plate 27 is lowered to open the conveyance path.

Next, when the air pressure in the air cylinder 16 is released, the feed pawl 12' advances to the solid line position 12 by the biasing force of the spring 15, pushes the electronic component 1, and moves it to the desired track rail (3A to 3H). 1).

As shown in FIG. 3, a plurality of feed pawls 12 (eight in this example) are arranged in a row on one feed bar 11, so during the above-mentioned operation, the plurality of feed pawls 12 All of them move up and down and back and forth in the same way, but one of them pushes the electronic component 1 on the classification rail 4,
The other feed claws all operate at idle (so-called idling). However, since one of the plurality of feed claws 12 is always facing the classification rail 4,
Electronic components on the classification rail 4 are surely transferred to a desired track rail.

[Effect of idea]

The sorting and conveying device according to the present invention includes a plurality of track rails for selectively conveying objects to be conveyed in parallel with the sorting rail, and the sorting rail is selected from the plurality of track rails. A feed bar with rows of claws corresponding to the plurality of track rails of the sorting and conveying device configured to be movable in parallel so as to face each other is disposed orthogonally to the conveying direction, and Means for reciprocating the bar in the vertical direction and in the conveyance direction is provided, and when the feed bar is operated, the conveyed objects on the sorting rail are pushed onto the selected track rail by the feed pawls arranged in a row on the feed bar. In addition, the shutter plate that moves in and out between the sorting rail and the track rail moves in and out in conjunction with the vertical movement of the feed bar, so electronic components, etc., which are transported objects, move in and out of the sorting rail. When transferring to a truck rail that is more needed, the feed bar that reciprocates up and down for transfer moves down and reciprocates, and only when the shutter plate moves down and retracts from the rail surface, the feed bar moves. When the object to be conveyed is not in the upward movement position, the shutter plate moves upward and protrudes from the rail surface, so that the object to be conveyed is not blocked by the shutter plate and is not conveyed. Moreover, the shutter plate has a simple configuration in which it is linked to the vertical movement of the feed bar, and has the effect of preventing classification errors.
In the present invention, since the classification rail is selectively moved to face a plurality of track rails arranged parallel to the classification rail, the necessary track rails can be moved in conjunction with the operation of the feed bar. This has the excellent practical effect of being able to transport the necessary objects without error.
