Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention mainly relates to an automatic slope gluing machine for automatically and continuously gluing slopes of trapezoidal wood pieces for lumber core plywood.

(Prior art) Conventionally, a trapezoidal piece of wood 2 sawn into a trapezoidal cross-section with a slope 2a as shown in Fig. 4 is attached to a lumber core core board A in which rectangular pieces of wood 1 with vertical side faces 1a as shown in Fig. 5 are laterally glued. In the lumber core core board B shown in FIG. 6, which is made by horizontally gluing the lumber core board B, the yield is very high because the raw wood is cut into trapezoidal pieces with a trapezoidal cross section at an angle of about 50 to 60 degrees. In order to accurately and completely horizontally glue these trapezoidal pieces of wood, glue must always be applied uniformly to the slopes of the pieces depending on the angle of the slope. Unlike the case of square pieces of wood, this cannot be done with conventional gluing machines, and in the past, there was no suitable equipment to automatically apply glue evenly to the slopes of these trapezoidal pieces of wood, and generally a primitive hand-painting process was required.

Therefore, it requires a lot of time and effort, is extremely inefficient, and cannot maintain a constant and stable amount of glue applied, resulting in an extremely high rate of adhesion failures, which in turn leads to defective lumber core plywood products. The major drawbacks of this industry were the overflow of the industry.

Conventionally, as a gluing device for gluing the butt ends of pieces of wood constituting a wooden frame, for example, a ruler board is fixed to each of two tables that move toward and away from each other with a neutral plane in between, and the glue is placed below the table. At the same time as arranging the glue tank, a device was installed to raise the thin glue plate immersed in the glue tank, and the forward position of one of the tables was changed to a set position where the two end surfaces lightly touched each other, and a set position where the two butt sides were lightly contacted, and a device was installed to raise the thin glue plate submerged in the glue tank. A stopper member provided on the table is engaged with a cam rod that controls the glue position in three positions: a gluing position where the butt end surface contacts the gluing plate in the open state, and a crimping position where the glued butt end surface is strongly pressed. An adhesive device with glue on the end surface. (Unexamined Japanese Patent Publication No. 52-
105938) is publicly known.

(Technical Problem) However, with these conventional devices, it has not been possible to stably and automatically apply glue uniformly to the slopes of the trapezoidal wood pieces of the lumber core core board. Furthermore, it was not easy to achieve adhesive adhesion that corresponded to the slope angle of the end face of the wood piece, and it was also impossible to apply it to trapezoidal wood pieces with different board thicknesses and widths.

(Technical Means) The present invention has been made to solve the above-mentioned technical problem, and embodiments of the drawings will be described in detail below.

First, 3 is a pasting roll 12 having a vertical roll axis on its upper surface, and a doctor roll 1 that engages with the pasting roll 12.
3, and a gluing motor 14
and a coating amount adjustment handle 15 are provided.
Reference numeral 4 denotes an inclined base plate which is pivotally attached to the support plate 5 on the machine base 3 by a pivot 6 so as to be able to finely adjust the inclination, and a guide ruler 16 fixed to the upper surface of the front edge of the inclined base plate 4.
The gluing roll 12 is adapted to be engaged with the notch 16a. (See Figure 2) and the first
In the figure, 7 is a screw shaft inserted vertically into the sheath tube 10 on the machine base 3, and a sliding (feather) key 11.
This allows it to move up and down without rotating. 8, the internal thread 9 of the boss part is connected to the screw shaft 7.
The handle 8 is provided with a boss mounted on the sheath tube 10 so as to be able to rotate freely, and the upper end of the screw shaft 7 is
It is in contact with the lower surface of the inclined base plate 4 so as to support it. Therefore, when the handle 8 is turned right and left as appropriate, the screw shaft 7 moves up and down, and the inclination of the inclined base plate 4 can be finely adjusted. Reference numeral 17 denotes left and right columns 18, 18 provided perpendicularly to the rear upper surface of the inclined base plate 4.
A handle 20 attached to the upper plate 19 installed between the upper ends
It is an elevating frame that can be moved up and down along the left and right columns 18, 18 by operation. Further, left and right side shafts 22, which are integral with the advancing/retracting frame 21 at the front end, are fitted into both left and right ends of the elevating frame 17 so as to be slidable back and forth. and left and right axes 22
By operating a handle 24 mounted on a rear plate 23 between the rear ends, the reciprocating frame 21 can be moved forward and backward while remaining parallel to the inclined base plate 4. 25 is a casing that is integrally attached to the lower surface of the retractable frame 21 in parallel with the inclined base plate 4;
At the center of the rear end of the belt cover 5, a belt cover 25a, which is integrated with the motor 26 disposed above, extends upward. And on the front edge inside the casing 25,
A plurality (six) of feed trochanters 27 whose trochanter axes are parallel to the inclined base plate 4 and perpendicular to the direction of the guide ruler 16 are arranged in parallel along the guide ruler 16.
Reference numeral 28 denotes an intermediate shaft in the front-rear direction at the center inside the casing 25, the rear end of which is connected to the motor 26 via a belt 31. Further, a series of adjustment bands 32 are entangled between the pulley 29 at the front end of the intermediate shaft 28 and each pulley 30 fixed to the shaft of each feed rotor 27, respectively. Then, each feed roller 27 is rotated by the rotation of the motor 26.
are designed to rotate in the same direction of the arrow. That is, a casing 25 in which electric feed rollers 27 are arranged in parallel.
is arranged so that it can be moved up and down by operating the handle 20 while remaining in a parallel state on the inclined base plate 4, and can be moved forward and backward by operating the handle 24. The slope 2a of the trapezoidal piece of wood 2, which is guided by the guide ruler 16 and transferred on the inclined bed plate 4 by the rotation of each feed roller 27, is automatically glued by the gluing roll 12. That is, in FIGS. 2 and 3, the trapezoidal piece of wood 2 that is being transferred sequentially in the direction of the arrow is located at the notch 16.
It is automatically glued to the slope 16a when passing a.

(Effects of the Invention) In this invention, since the trapezoidal wood piece is transported at an angle so that the slope to be glued is vertical, it is possible to stably glue the slope without deteriorating the function of the glue roll, and in particular, to The trapezoidal piece of wood is guided by the guide ruler on the inclined bed plate by the rotation of the feed trochanter, and the slope is automatically glued with a gluing roll, so that the trapezoidal piece of wood swings randomly during the transfer process. It has the excellent effect of always being able to perform stable gluing with a uniform coating amount.

In addition, since the casing equipped with the electric feed trochanter can be moved up and down and moved forward and backward by operating the handle while remaining parallel on the inclined bed plate, the thickness can be adjusted and the feed trochanter can be adjusted according to the size of the trapezoidal piece of wood. The effect is that the contact part can be adjusted freely and easily by operating the handle. Furthermore, the inclination of the inclined bed plate can be finely adjusted to accommodate the slope angle of the trapezoidal piece of wood.
