2. Description of the Related Art At present, a timber building material used in a wooden house is manufactured by a so-called pre-cut, in which processing such as a connection or perforating the wood is automatically and continuously processed by various woodworking machines. Factory production.

[0003] For this reason, a conveyor is used to transport wood to each woodworking machine, and the transport line is often used in an L-shaped orthogonal connection depending on the layout of a factory. In this line, a long piece of wood may be fed horizontally to the conveyor in a direction perpendicular to the conveyor, and may be delivered to a vertically fed conveyor.

[0004] In the case of this horizontal feed, if it is not delivered to the vertical feed conveyor in an accurate orthogonal state to the conveyor, it will of course interfere with the processing in the next step.
It may not be properly placed on the vertical feed conveyor, and may cause troubles such as transfer mistakes and dropping of wood.

For this reason, as shown in FIG. 9, in a conventional conveyor line 80, a stopper 82 is provided at the end of a transverse conveyor 81, and the lumber 83a is once brought into contact with the stopper 82 so that its posture is changed. Are corrected so as to be orthogonal to each other, and the wood 83a is stored in a connected state pressed by the next wood 83b which is continuously transferred.

Therefore, when the frontmost wood 83a of the conveyor 81 is taken out by the plate-shaped delivery member 84, the wood 83a interferes with the next adjacent wood 83b at the time of the separation, and the skins of the woods 83a come into contact with each other. These timber 83
a, 83b are arrows p, p ′ as shown in FIG.
, And eventually falls down.

Further, various sizes of wood are supplied to the conveyor line 80. For example, in the processing of beams and girders, those having a width of 90 mm to 150 mm are transferred randomly or periodically. And a delivery member 84 capable of accommodating these various dimensions is provided by a transverse conveyor 81.
And a vertical feed conveyor 85.

The maximum width of the delivery member 84 must be 90 mm or less in order not to interfere with the next adjacent wood 83b. As shown in FIG. 9 (b), a position near 50% of the material width may be the foremost end 84a of the delivery member 84 due to the bending of the wood 83a, etc. Wood 8 placed on
3a, 83b transfer the frontmost piece of wood 83a to the delivery member 8;
When trying to remove from this conveyor 81 by 4
Further, as shown in FIG. 9 (a), a phenomenon occurs in which the tilt occurs in the directions of arrows p and p '. And other various problems.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of an article conveying apparatus and method according to the present invention.

In FIGS. 1 and 2 and FIGS. 4 to 8, reference numeral A denotes an article transfer device, for example, a transfer line for supplying the wood b to each woodworking machine when processing an article b which is wood used for a wooden house. And a transport means 1;
It is basically composed of the trochanter 2, the operating means 3, and the delivery means 4.

The above-mentioned transporting means 1 has an endless chain 5 such as a chain stretched thereon and runs continuously or intermittently in one direction by an operating member 1a such as a motor, as shown in FIG. The long article b is provided over a plurality of strips so that the long article b can be reliably supported.

The above-described trochanter 2 is rotatably supported by the support means 6 by a support shaft 6 in a free-rotating (rotating) state, and supports the lower surface of the article b. 3, a large number are provided at a predetermined pitch.

The operating means 3 controls the rotation of the trochanter 2 by contacting the surface of the trochanter 2 below the conveying means 1.

That is, even if the transfer state of the article b on the transfer means 1 is made faster or slower than the transfer speed of the transfer means 1, and even if the transfer means 1 is in operation,
This stops the apparent transfer of the article b.

As one of the means, FIG. 1 and FIG.
As shown in FIG. 5, a flat plate fixed to the machine frame 7 of the transfer means 1 is used, and the trochanter 2 comes into contact with the flat transfer means 1 to exert a friction. When the trochanter 2 reaches the operating means 3, the conveying means 1 traveling in the direction of the arrow p 1 indicated by 4 is pressed against the operating means 3 by the load of the article b.

Then, the trochanter 2 rotates on the operating means 3 in the direction of the arrow p2 shown in FIG. 4, and this rotational force is transmitted to the surface of the article b and is increased from the transfer speed of the arrow p1. Transfer is given.

Therefore, in FIG.
b are separated from each other at a predetermined interval h.

As shown in FIG. 6, the operating means 3 is provided with an operating member 8 such as a fluid cylinder for making contact with and separating from the trochanter 2 as necessary. By setting the time, the separation interval h between the articles b and b is set.
Can be adjusted arbitrarily.

Further, as another example, as shown in FIG.
In some cases, a driving means 10 for contacting the trochanter 2 and positively driving the trochanter 2 by a driving member 9 such as a motor (which may be a servo motor) is provided. The suspension 3a such as a flat belt or the like is used, and when the driving member 9 rotates forward or backward and stops driving, the suspension 3a runs or stops, and the articles b, b The separation interval h between them can be adjusted arbitrarily.

The delivery means 4 is provided on the downstream side of the transport means 1 to transfer the article b in the front row on the transport means 1 to the next step. As shown in FIG. A movable body 13 is slidably engaged with the guide 12 by an advancing / retreating member 14 such as a fluid cylinder, and a support 16 which is movable up and down by an elevating member 15 such as a fluid cylinder is attached to the movable body 13.

As a result, the article b which has reached the transfer end of the transport means 1 is lifted above the transport means 1 as the support 16 is raised by the elevating means 15, and then the support 16 is advanced by the advance / retreat member 14. Accordingly, the transporting means 1 moves from the transporting means 1 to a delivery means 17 such as a roller conveyor provided adjacent to the transporting means 1 and further supports 16
Is delivered to the sending means 17 by the lowering of

In FIGS. 1, 2 and 5, 18
Is a stopper, which is provided at the end of transfer of the transporting means 1 and regulates the transport of the frontmost article b on the transporting means 1. The stopper can also correct the row of articles b if necessary.

Further, in FIG. 2, reference numeral 20 denotes an article line detecting means, which uses, for example, a transmission type or reflection type photoelectric tube or a laser beam. When a plurality of articles are provided in one row, and at least two of them detect the article b, the article b assumes a normal transfer posture substantially orthogonal to the transfer direction of the transport means 1 of the article b.

In FIG. 2, the article b is not necessarily
Not only long objects transported across the transporting means 1 but also transporting means 1 such as ~, ~, ~ are used. The detecting means 20 is arranged so as to correspond.

Therefore, the article conveying apparatus A and the method thereof according to the embodiment of the present invention configured as described above have the following effects.

First, as shown in FIGS. 1, 2 and 5, a large number of long articles b are placed side by side on a plurality of conveying means 1 and placed and supplied in a laterally fed state. I do.

When the article b in the front row reaches the flat operating means 3 as shown in FIGS. 1 and 4, the trochanter 2 provided on the conveying means 1 comes into contact with the operating means 1, and , Rotating in the traveling direction of the transport means 1.

Therefore, the article b placed on the trochanter 2
Is pushed in the traveling direction of the conveying means 1 with the rotation of the trochanter 2, so that a predetermined interval h is provided between the article b and an adjacent subsequent article b in close contact with each other.

In this state, the article b that has reached the position of the stopper 18 is placed on the support 16 by the operation of the delivery means 4, passes over the stopper 18, and is delivered to the delivery means 17.

As a result, as shown in FIG. 8A, the article b having a width about twice as large as the width of the support 16 is changed to an article b having a width smaller than the width of the support 16 as shown in FIG. 8B. Even
The article b can be smoothly delivered from the transport means 1 without causing delusion.

In particular, as shown in FIG. 8B, even when the rear edge 16a of the support 16 protrudes from the width of the article b, the next article b adjacent to the article b is moved to the rear edge 16a.
And does not adversely affect the mounting posture on the transport means 1.

Another operation of the operating means 3 is that the article b in the front row on the conveying means 1 is
When the value reaches 0, when the article b is detected to be in a normal transfer posture, that is, a state in which the article b is transported obliquely with respect to the transport unit 1, the posture of the article b is corrected before being transferred to the sending unit 17. Is done.

That is, by using the positively-driven operating means 3 as shown in FIG. 7, for example, as shown in FIG. The operating means 3 is operated to control the operation of the operating means 3 for contacting the trochanter 2 to run or stop with respect to the trochanter 2.

In this control, by appropriately adjusting the rotation stop of the driving member 9 for driving the suspension body 3a in the operation means 3, the operation means 3 can be operated smoothly, and in FIG. The article b transferred to the position of the row detecting means 20 is corrected to the posture indicated by the imaginary line in FIG.

As shown in FIG. 6, even when the operating means 3 is of a plate-type elevating type, the contact time of each of the operating means 3 to the trochanter 2 by the elevating member 8 can be reduced. By appropriately controlling the timing, the purpose of the posture correction of the article b can be achieved.

[0042]

According to the present invention having the above-described structure, even if the posture of an article placed on the conveying means in a laterally-forwarded state is oblique, the operation provided on the conveying means can be improved. By this means, the posture can be easily and reliably corrected to the posture orthogonal to the conveying means.

Even if articles supplied in a continuous state are transported in contact with each other, when the operating means reaches the transfer terminal end of the transport means, cuts are formed at predetermined intervals between the articles. Therefore, when the article is delivered by the delivery means to the next process, the article does not fall over due to interference between the articles and the placement posture on the transport means does not collapse. And so on.
