Description

  The present invention relates to a method and apparatus for transporting wood (plate material) (hereinafter simply referred to as wood) by a transport mechanism such as a conveyor or a roller, and its apparatus, in particular, the wood at a right angle or a predetermined angle from a certain direction. The present invention relates to a method and apparatus for transporting wood, which can be quickly and easily moved in the next direction when transporting in a different direction.

In a wood processing factory, when processing wood to a predetermined length and aligning the length and thickness, or by applying finger processing to the edge of the plate material to produce a laminated material of a predetermined length, It feeds in a certain direction with a transport device using rollers, and further feeds the next feed in a direction perpendicular to the previous feed direction, and transports and processes the wood while effectively using the space in the factory. As such a wood conveying method or apparatus, the edge of the plate material is conveyed by a roller conveyor arranged in a predetermined direction while fingering, and is brought into contact with a backing plate, and next in a different direction with respect to this direction. A method is known in which a roller conveyor is arranged to perform the following processing (Patent Document 1, FIG. 5). However, such a method is not always reliably fed at a constant speed due to uneven rotation of the roller conveyor.
JP-A-8-91559

Therefore, as a conveying method for reliably feeding the wood in a right angle or a predetermined angle direction, for example, as shown in FIG. 9, the wood W (W ₁ , W ₂ , W ₃ ,. ..) etc. along the ruler 2 by the transport mechanism 1 using the conveyors 1a, 1a, and the like, and the timbers W that are lined up are quickly pulled out one by one in the vertical direction in the perpendicular direction and sent to a predetermined position. It is also conceivable to carry out processing sequentially (processing necessary for the edge, front surface and back surface). In this case, the chain 3a of the vertical transport mechanism 3 is wound around the sprockets 9 and 10 and rotated endlessly, and the wood 3 (W ₁ , W ₁ , W W ₂ , W ₃ ,...) Are sequentially brought into contact with each other, and the rollers 4, 4,. Place the stopper gate 6 that slides so that it can be widened or narrowed according to the width of the wood so that it can pass only one by one at the end of the ruler 2 in the longitudinal feed direction. It is also considered here to put it.

  Usually, the friction coefficient between wood and wood is larger than the friction coefficient between iron materials such as chains and wood. Therefore, it is difficult to pull out the woods one by one in the vertical direction and feed them by the above method. Therefore, as shown in FIG. 10, a method of transporting the wood that is in contact with the chain transport mechanism 3 by driving the upper vertical feed drive roller 11 is conceivable. That is, when the behavior of the drive roller 11 is shown in FIG. 11, as shown in FIG. 11A, while the wood W does not come, the drive roller 11 for vertical feed is raised to some extent, When it comes, as shown in FIG. 11B, the upper vertical feed drive roller 11 is lowered and pressed against the wood W to drive it, and the vertical feed drive roller 11 forcibly feeds it in the vertical direction. Next, after the wood W is fed, as shown in FIG. 11C, it becomes an obstacle when the next wood is fed vertically, so that the next wood W comes up by raising the vertical feed drive roller 11. If you wait, you can think of a good configuration. However, in this case, as shown in the figure, a vertical feed force can be obtained sufficiently, but an elevating mechanism 12 that moves the vertical feed drive roller 11 together with the motor 13 is required. In addition, it is necessary to drive up and down in a timely manner, which not only takes time for processing, but also complicates the entire material feeding mechanism and causes an increase in cost.

  The present invention makes it possible to smoothly convey wood (plate material) in a short time with a simple mechanism while using seven structures such as a chain when the wood (plate material) is longitudinally fed from a transverse feed, which requires a complicated mechanism, time and cost. It aims at providing the conveyance method and apparatus of wood which solved the problem of.

For this reason, it can be set as the conveyance method and apparatus of the timber which did not require a complicated mechanism and reduced cost.

The best mode of the present invention will be described below.
FIG. 1 is a plan view showing an outline of a transport apparatus according to a first embodiment used in the wood transport method of the present invention, FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1, and FIG. FIG. FIG. 4 is a view taken along arrow B-B in FIG. In addition, the same component is demonstrated using the same code | symbol as what was shown in FIG. 9 thru | or FIG.

This wood conveying device is a conveying mechanism 1 (mechanism for conveying by conveyors 1a, 1a, 1a) that conveys a large number of woods W (W ₁ , W ₂ , W ₃ ,. A ruler 2 for contacting the end of the wood, a conveying mechanism 3 for vertical feed, an upper vertical feed drive roller 5 driven to rotate by a rotating shaft 7 of a motor 8, and a lower roller for vertical feed It is composed of 4, 4,. Further, the motor 8 and the rotary shaft 7 are slightly elastically displaced when the wood W enters between the upper vertical feed driving roller 5 (hereinafter simply referred to as the drive roller 5) and the vertical feed lower conveying roller 4. It is. A stopper gate 6 is installed between the end of the ruler 2 and the vertical feed conveyance mechanism 3 so as to be able to widen and narrow according to the width of the wood. A chain 3a is used for the vertical feed transport mechanism 3, and the chain 3a is wound around a drive sprocket 9 and idler sprockets 10, 10, and driven. In addition, the mechanism 1 which conveys the said wood side by side is not limited to the conveyor 1a but may be a conveyance mechanism using a chain, a roller, or the like.

The drive roller 5 has a taper 5t formed on the wood W side, and as shown in FIG. 4, notches 5c and 5c are formed on the top and bottom. As will be described later, the notches 5c and 5c are for bringing the wood W conveyed in the lateral direction by the conveyors 1a and 1a into contact with the chain 3a of the conveying mechanism 3 for vertical feeding as it is. is there. That is, as described above, when the notches 5c and 5c are not provided, the wood W (W ₁ , W ₂ , W ₃ ,...) Being fed collides with the taper 5t of the drive roller 5. To get in the way. However, if a vertical drive mechanism is provided that raises the drive roller 5 every time the wood comes and lowers the drive roller 5 when the drive roller 5 comes into contact with the chain 3a, it takes time for processing and the processing efficiency deteriorates (see FIG. 11). ). Therefore, as shown in FIG. 4, even if the wood W (W ₁ , W ₂ , W ₃ ...) Being fed is fed as it is by the conveyor 1a, the wood 5 W is moved down the notch 5c of the drive roller 5. When facing the side, the drive roller 5 is cut so that a gap d is formed so that the wood W can pass between the cut surface 5b of the cut portion 5c and the feeding surface of the lower roller 4. The notches 5c and 5c are formed.

The operation in the case where the transport device for carrying out the method for transporting wood according to the present invention is configured as described above will be described. First, the stopper gate 6 at the end of the ruler 2 is adjusted to the width of the wood W and adjusted so that it is discharged one by one, and the conveyance is started.
The most advanced wood W ₁ that has been fed in the lateral direction along the ruler 2 comes into contact with the taper 5t of the drive roller 5 as shown in FIG. When the wood W ₁ comes into contact with the taper 5t of the drive roller 5, the wood W ₁ is pushed by the rear wood W ₂ from behind, and therefore the drive roller 5 is pushed. When the notch 5c of the driving roller 5 comes, the wood W ₁ is instantaneously formed between the notch 5c of the driving roller 5 and the lower conveying roller 4 as shown in FIG. It enters between and is pushed further and comes into contact with the chain 3a. The wood W ₁ is pushed out in the longitudinal direction so as to be pushed against the drive roller 5. When the previous wood W ₁ is pushed out, the next wood W ₂ is similarly brought into contact with the chain 3a and vertically fed. Thus, the wood W ₁ is pushed out in the vertical direction so as to be pushed against the driving roller 5. This operation is repeated until it is necessary.

The drive roller 5 is always rotated when the wood W is fed vertically. When the leading edge of the wood W ₁ of the conveying mechanism 1 for conveying side by side timber W laterally abuts the tapered 5t of cross-feed has been driven roller 5, the rotary shaft 7 and the drive roller 5 (by motor 8) Elastic Since they are displaced, they instantaneously enter the gap d between the notch 5c of the drive roller 5 and the lower conveying roller 4 and are longitudinally fed with a relatively strong conveying force.

  As described above (see paragraph 0004), the coefficient of friction between wood and wood is larger than the coefficient of friction between iron materials such as chains and wood. However, as shown in FIG. 6, when the drive roller 5 is driven to rotate while the wood W is interposed between the notch 5c and the lower conveying roller 4, the notch 5c of the drive roller 5 is driven. Elastic deformation corresponding to the difference h between the notch surface 5b and the outer peripheral surface 5a without the notch 5c occurs. The reaction force that causes this elastic deformation becomes the pressing force, and the force multiplied by the reaction force and the friction coefficient becomes the force that feeds the wood W of the drive roller 5 in the vertical direction, so that the wood W is surely delivered together with the conveying force of the chain 3a. Can be sent out vertically.

  The difference h between the notch surface 5b of the notch portion 5c of the drive roller 5 and the outer peripheral surface 5a without the notch portion 5c is as shown in FIG. A spring (not shown) may be installed so that the rotating shaft 7 of the driving roller 5 is absorbed by the bending or the rotating shaft 7 of the driving roller 5 is bent up and down. Alternatively, it is possible to provide a mechanism that is elastically deformed so that the lower vertical feed roller 4 and the like are bent.

Next, FIG. 8 is a figure which shows 2nd Embodiment of the conveying apparatus used with the conveying method of the timber of this invention. That is, in this conveying apparatus, the drive roller 5 is formed with a plurality of spiral grooves 5g, 5g,... Instead of the notch portion 5c on the outer peripheral surface. In the first embodiment, the notches 5 c and 5 c are formed on the outer peripheral surface of the drive roller 5. In short, it suffices that the wood W that has been laterally fed can smoothly come into contact with the chain 3a of the transport mechanism 3 for vertical feed during vertical feed. Therefore, when the timber W ₁ of the cutting edge is in contact with the tapered 5t surface of the driving roller 5, the wood W ₁ of the outermost tip, pushing the tapered 5t surface of the driving roller 5, rose on slightly elastically displaced when the spiral grooves 5 g, 5 g, when the edge of the wood W ₁ to part of the end of ... engages the spiral groove 5 g, 5 g, the wood W ₁ is drawn in ... is in contact with the chain 3a, It is fed longitudinally by the drive roller 5.

  Although the specific best embodiment of the present invention is as described above, it is possible to replace a part of the apparatus with a separate one. For example, although the chain 3a is used in the transport mechanism 3 for vertical feeding, a belt (in particular, a belt having a large friction coefficient) may be used instead of the chain 3a. Further, instead of the lower conveying roller 4, a conveyor or a chain conveying mechanism may be provided. The feeding direction of the wood w may be transferred not only in the perpendicular direction but also in the oblique direction such as 45 degrees or 60 degrees. Further, the cutout portion 5c provided in the upper vertical feed drive roller 5 may be provided at one place or at four places. The number of spiral grooves 5g provided on the drive roller 5 may be increased or decreased. The angle of the spiral groove 5g can also be changed as appropriate.
