Abstract

(57) [Summary] [Structure] The piercing body 6 has a shank portion 6a having a length sufficient to sufficiently penetrate the single plate S, and a blade portion 6 at the tip thereof.
b, and the shape of the cross section of the shank portion 6a orthogonal to the longitudinal direction is such that the long side 6c is positioned with respect to the fiber direction of the conveyed single plate S, and the blade portion 6b is parallel to the fiber direction. It is formed on the conveyor belt 5. [Effect] When the piercing body provided on the veneer veneer conveyor belt pierces the veneer, the amount by which the fibers of the veneer are spread in the direction orthogonal to the fiber direction is small, and the deformation is within the elastic range of the veneer. Therefore, the frictional force acting between the piercing body and the veneer is large, and the veneer can be held by the frictional force.
Since scars due to the puncture of the piercing body hardly remain on the veneer, it can be used for the veneer of the surface such as plywood and LVL.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a conveyor belt for piercing and holding a veneer veneer (hereinafter referred to as a veneer).

[0002]

[Prior art]

 Conventionally, the shape of the piercing body of a belt for piercing and transporting a single plate from its upper surface is such that the existing shank portion uses a piercing body having a cylindrical shape, a conical shape, or a pyramid shape, as described in Japanese Utility Model Publication No. 61-34332. The cross-sectional shape orthogonal to the piercing direction of the part where the veneer was pierced was a circle or the like. Therefore, as shown in FIG. 5, the fibers of the single plate may be largely spread in a spindle shape in a direction orthogonal to the fiber direction, and the fiber structure may be plastically deformed or destroyed, and the elasticity of the spindle-shaped puncture hole may be increased. This makes it difficult to hold the veneer by the frictional force acting between the piercing body and the veneer. In the above publication, in order to ensure the holding, the veneer is provided with a protrusion at the tip of the veneer to convey the veneer. It is configured to hold the single plate by locking the lower surface of the.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned device, although the holding force is ensured, a trace of a puncture scar remains on the veneer due to the plastic deformation or destruction of the large-diameter protrusion when passing through the puncture hole. Such veneer could not be used on the surface of plywood, LVL, etc.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention is a veneer veneer transport belt that has inherited the basic idea of the past and has a higher degree of perfection, and its configuration is the same as the above-mentioned transport belt for implanting a piercing body for piercing a veneer veneer. The tip of the piercing body has a blade parallel to the fiber direction of the veneer veneer to be conveyed, and the shape at the cross section orthogonal to the piercing direction of the part where the veneer veneer is pierced is the fiber. It is configured as a substantially rectangular shape that is long in the direction.

[0005]

[Action]

 With the above configuration, when the piercing body pierces the veneer, first, the blade is pierced in parallel with the veneer, and the amount of the fiber of the veneer spread in the direction orthogonal to the fiber direction is small, and the elasticity of the veneer is substantially Since the deformation is within the range, the frictional force acting between the piercing body and the veneer is large, the veneer can be held by the frictional force, and scars due to the piercing of the piercing body are hardly left on the veneer.

【Example】

 A veneered veneered conveyor belt according to the present invention will be described below with reference to the drawings. 1 is a plan view of the carrier device, FIG. 2 is a side view of FIG. 1, and 1 is a carrier device to which a carrier belt according to the present invention is attached. The carrier device includes a drive shaft 3 and a driven shaft 4. Two conveyor belts 5a and 5b stretched on the front pulley 3a and the rear pulley 4a, which are fixed to each other, and a plurality of piercing members 6 planted in the outer surface longitudinal direction of the conveyor belts 5a and 5b. And a fixed frame 7 having a guide portion 7b which is attached to a base (not shown) of the transport device and which guides and supports the transport belts 5a and 5b.

The piercing body 6 is made of stainless steel or the like, and as shown in FIG. 3, it comprises a shank portion 6a having a length sufficient to penetrate the single plate S and a blade portion 6b at the tip end thereof. The shape of the cross section of 6a orthogonal to the longitudinal direction is such that the long side 6c is located with respect to the fiber direction of the conveyed single plate S, and the blade portion 6b is formed on the conveyor belt 5 in parallel with the fiber direction. That is, in the transporting device that transports the veneer S so that the fiber directions of the veneer S are orthogonal to the transport direction of the transport belts 5a and 5b, the long side 6c of the shank portion 6a provided on the transport belts 5a and 5b. The blade portion 6b is formed so as to be orthogonal to the carrying direction. In the state of implanting the piercing bodies on the conveyor belt, the rows of the piercing bodies 6 to be implanted may be provided in two or more rows depending on the width of the conveyor belt, as in the conveyor belt 5a shown in FIG. 5b may be arranged irregularly without forming a row while keeping the interval between the adjacent piercing bodies 6 below a certain distance, and by doing so, more piercing bodies per unit area of the conveyor belts 5a, 5b may be provided. Since 6 can be attached, the holding ability of the piercing body 6 can be improved by the repulsive force of the fibers between the piercing bodies 6, 6.

Further, in the figure, 8 is a drive member for rotationally driving the drive shaft 3, and 9 is a backing belt that is attached to the back surface of the conveyor belt and that fixes the head of the piercing body 6. .

The operation of this embodiment will be described. When the veneer S is carried in to the side of the conveyor 1 by the driving of the carry-in conveyor 2, the fibers of the veneer S are regulated by the guide portion 7b in accordance with the rotational driving of the carrying belts 5a and 5b. It is sequentially press-fitted at two points in the direction, and the single plate S is stabbed and held vertically from the upper surface. During the stab-holding, the fibers of the veneer S into which the puncture body 6 is press-fitted are not cut in the plane orthogonal to the longitudinal direction thereof, and the blade portion 6b is inserted between the fibers, so that the shank portion 6a is formed. The puncture holes are formed while pushing the fibers apart. In this state, the veneer is conveyed while being firmly pierced and held by the frictional force caused by the opposite elastic force of the fiber due to the pierced hole that has been spread. The veneer transported by the transport belt is pierced by vertically moving a rod-shaped pressing body provided in parallel with the transport belts 5a and 5b between the transport belts 5a and 5b above the deposition device. Remove from body and deposit. Incidentally, in the conveying device that conveys the veneer parallel to the conveying direction of the conveying belts 5a and 5b, even if the long side 6c is attached to the conveying belts 5a and 5b in parallel with the conveying direction. Good

Next, an embodiment in which the shape of the piercing body 6 is changed will be described. The blade portion 6b of the piercing body 6 is a portion of the piercing body 6 that first comes into contact with the veneer S when the veneer S is press-fitted, and it is not necessary to be sharp enough to cut the fiber. Absent. The portion parallel to the fiber direction of the transported veneer veneer is the longitudinal portion of the shape in a cross section orthogonal to the piercing direction of the blade portion 6b, and when the tip has a square cross section, In addition, the short side length can maintain the resilience of veneer fibers. Further, the shank portion 6a has a smoothly continuous surface without a step difference from the blade portion 6b, and since the length of the long side 6c is longer than the diameter of the conventional piercing body, the contact area with the fiber is wide and the frictional force is also large. . The shape of the shank portion 6a in a cross section orthogonal to the piercing direction of the portion where the veneer veneer is pierced is substantially rectangular long in the fiber direction and has at least a long side 6c parallel to the fiber direction. Is enough. Therefore, the short side 6d is one side of the rectangle that is orthogonal to the long side 6c as shown in FIG. 4 (a), or the piercing body 6 between the long sides 6c, 6c as shown in FIG. 4 (b). It may be one that projects into the gap created by the thickness. Further, as shown in FIG. 4 (c), the cross section of which is close to an ellipse is substantially rectangular so that the area of contact with the fibers is further increased.

[0011]

[Effect of device]

 According to the present invention, when the piercing body provided on the veneer veneer conveyor belt pierces the veneer, first, the blade portion is pierced in parallel with the veneer, and the fibers of the veneer are moved in the direction orthogonal to the fiber direction. Since the amount of expansion is small and the deformation is within the elastic range of the veneer, the frictional force acting between the piercing body and the veneer is large and the veneer can be held by the frictional force. Since the scars caused by the punctures on the veneer hardly remain on the veneer, it can be used for the veneer of the surface such as plywood and LVL.
