Description

[Detailed description of the invention] The present invention relates to a ruler setting device for veneer veneer, and its purpose is to provide a ruler for veneer veneer (hereinafter simply referred to as veneer) regardless of its degree of flatness. To provide a ruler setting device capable of quickly setting a ruler.

As is well known, in the process of manufacturing plywood, it is necessary to measure the veneer at various steps, for example, as disclosed in "Automatic veneer pasting method" (Japanese Patent Publication No. 55-45003). When drawing out a ruler on the end face perpendicular to the fibers of the veneer, as shown in FIG. 1, for example, as shown in FIG. A ruler 3 is disposed perpendicularly to the conveyance direction of the rotary bodies 2 on the lower side in the conveyance direction of a plurality of rotary bodies 2 arranged in parallel at intervals of . The fibers are moved in the same direction by using a ruler device 1 which is provided with a ruler, and a transfer device 5 as disclosed in, for example, "Method and device for transferring a plate-shaped object" (Japanese Patent Publication No. 55-34739). Veneer 6 transferred to
is continuously conveyed in the same direction as the fibers by a rotating body 2, and its tip end surface is brought into contact with a ruler 3.

7 in the figure is a conveyor belt of a transfer conveyor that transfers the veneer from which the ruler has been taken out to the next process, and the ruler is detected from a veneer detector (not shown) consisting of a phototube, etc. installed near the ruler. Actuating device consisting of a fluid cylinder, etc. based on the discharge completion signal (not shown)
As a result of the operation, it rises to the position indicated by the dotted line as indicated by the arrow in the figure, and supports the veneer in a curved manner while transporting it in a direction perpendicular to the fibers.

However, as is well known, not all veneers are flat, and there are many veneers with wavy undulations, but when veneers with such undulations are transferred to the conventional ruler-setting device, In order to prevent collision between the tip of the veneer and the rotating body, a part of the veneer guide is placed in contact with the rotating body and receives braking, and as shown in the figure, the outer circumferential shape is the center of rotation. In the case of a conventional general rotating body that forms a concentric columnar shape, the conveying force does not change the braking state, especially after a part of the tip contacts the ruler. There was a problem where there was a shortage and there was a significant delay in putting out the ruler.

Furthermore, if we attempt to avoid the above-mentioned problem by positioning the veneer guide further down, only a portion of the tip of the veneer will collide with the rotating body, resulting in the inconvenience of being damaged or torn. Therefore, it becomes necessary to slow down the transfer (insertion) speed itself, and as a result, a decrease in efficiency is unavoidable.

Therefore, in the ruler setting device according to the present invention, the outer peripheral shape of at least one of the plurality of rotating bodies is shaped like an irregular column with respect to the center of the rotating body. It is configured to apply vibration to the veneer using a rotating body, and even if a part of the veneer with undulations comes into contact with the veneer guide and is braked, the braking state will not change due to the vibration of the veneer. Since the conveyance force of the rotating body is changed, the conveying force of the rotating body effectively acts on the veneer, and as a result, the ruler can be set out quickly.

Hereinafter, the present invention will be described in more detail based on an example of implementation illustrated in the drawings, but members having the same configuration as the conventional ruler setting device will be designated by the same reference numerals, and the explanation thereof will be omitted.

FIG. 2 is an explanatory side view of the ruler setting device according to the present invention, and 2a in the figure is a rotating body that constitutes a characteristic part of the ruler setting device 1a according to the present invention, and as is clear from the figure, The outer circumferential shape is formed into an irregular columnar shape (in the example, a hexagonal columnar shape) with respect to the center of rotation, and the veneer 6 is transferred in the same direction as the fibers by the transfer device 5, and is It is configured to apply vibration.

Therefore, even if a part of the veneer 6 having undulations comes into contact with the veneer guide 4 and is braked, the rotating body 2a applies vibration to the veneer 6 to change the braking state and prevent it from rotating. Since a conveying force is applied to the veneer 6 together with the body 2, the braking condition is released or relaxed and the ruler is quickly set out.

In addition, it is preferable to select the number and position of the rotating bodies that apply vibration to the veneer as appropriate depending on conditions such as the length and thickness of the veneer or the total number of rotating bodies. In addition, specific examples of the outer circumferential shape include, in addition to the polygonal columnar shape as in the above embodiment, an elliptical columnar shape as shown in FIG. 3, an eccentric columnar shape as shown in FIG. 4, and There are various types of cylindrical shapes, such as a cylindrical shape with knobs that have a large number of smooth protrusions protruding in a distributed manner, as shown in Fig. 5.In short, it is sufficient that the cylindrical shape is irregularly shaped with respect to the center of rotation so that vibration can be imparted to the veneer. As long as it has a similar outer peripheral shape, that is, an external appearance, its internal structure may be either solid or hollow.

Furthermore, the ruler is not limited to the flat fixed ruler as in the above embodiment, but for example, although not shown, there is a "veneer veneer tilt correction device" (Japanese Patent Publication No. 57-52881).
As disclosed in , a movable ruler using two movable rulers that synchronously open and close in a composite direction of the veneer conveyance direction and the ruler direction by the action of a link to facilitate the ruler removal action. Or, for example, "Position control device for veneer veneer"
As disclosed in the Japanese Patent Publication (No. 2003), even in the case of a rotary ruler using two rollers, each of which rotates independently to facilitate the ruler-setting action, the point is that the tip surface of the veneer is brought into contact with the ruler. Of course, the means for transferring the veneer to the ruler ejecting device and the means for transferring the veneer from the ruler ejecting device are not limited to those in the above-mentioned embodiments, but any conventionally known means can be used. Various means can be applied.
