Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is a method of manufacturing a laminated wood, which is made up of a plurality of wooden boards coated with an adhesive, by applying a plurality of pressure points that are arranged upright on a base along a forming line in advance. It relates to a molding machine for curved laminated wood that bends and molds the glulam into a predetermined shape by crimping it onto a clamping post and holding this state until the adhesive hardens. This invention relates to a clamping post setting device that automatically moves and sets a clamping post along a base.

(Prior Art) As a conventional art, there is a structure shown in FIGS. 3 and 4.

That is, a full-size template 2 previously formed into a predetermined shape is placed on a base 1, and a large number of clamping columns 3 are arranged in an upright manner along the template 2 on its back surface 2b (lower surface in FIG. 3). After that, the clamping column 3 was bolted and fixed to the base 1.

Then, as shown by the imaginary line in FIG.
A laminated timber 4 made up of a plurality of wooden boards coated with an adhesive is placed on the front side (the top surface in Fig. 3) of the clamping support 3, and the straight part of one end is attached to the corresponding clamping support. 3, as shown in FIG. 4, the clamping plate 5 and the clamping tool 6 are used to clamp and fix, that is, clamp, and the other end is moved in a curved manner in the corresponding clamping column 3 direction using a winch, etc., and the clamping plate is 5
Then, the other end side was sequentially pressed onto the pressing column using a pressing tool 6, thereby bending and molding the laminated timber 4 into a predetermined shape.

(Problems to be Solved by the Invention) The conventional method described above requires a full-size template when setting the clamping column as a base, so it takes a lot of effort and time to manufacture this template. There were flaws.

Furthermore, the clamping struts are generally fixed to the base with bolts, etc., but when the clamping struts are arranged along the forming line of the laminated wood to be molded, the bolt holes on the clamping strut side and the base side The bolt holes may not match, and in this case, you will have to create new bolt holes or create special fasteners.
There was a drawback that it required a lot of labor and time to fix the clamping column to the base.

An object of the present invention is to obtain a new device for setting a clamping strut in a curved laminated wood forming machine that eliminates the above-mentioned drawbacks.

(Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows.

That is, a large number of clamping columns are arranged in parallel on a base, and guides are provided to connect each clamping column to the base so that each clamping column can move in a direction substantially orthogonal to the arrangement direction, and An adjustment mechanism capable of withstanding load and capable of independently moving and adjusting each clamping column along a guide during operation is provided, a drive mechanism is provided for driving each adjustment mechanism, and each drive mechanism is driven by a data input signal. The configuration is such that a control device is provided to control the amount.

(Function) Since the present invention has the above structure, when a predetermined data signal is input to the control device, each adjustment mechanism whose drive mechanism is controlled is operated by a predetermined amount.

As a result, they are moved along each clamping column guide and arranged on a forming line of a predetermined shape.

Furthermore, the clamping columns arranged on the molding line of a predetermined shape are connected and held to the base at respective positions by respective guides and respective adjustment mechanisms.

(Example) Embodiments of the present invention will be described below based on the drawings.

First, in the drawings, FIG. 1 is an explanatory view showing the basic configuration of the present invention, and FIG. 2 is a perspective view showing the structure of one set of clamping struts.

10 is a base, and on this base 10 a large number of clamping columns 11 are arranged upright in parallel at a predetermined pitch, for example, about 300 mm.

As shown in FIG.
1a are connected by a clamping tool 11b consisting of a pair of upper and lower bolts and nuts.

Further, each of the clamping columns 11 is individually connected to the base 10 via a rail 12 that serves as a guide and a threaded groove 13 that serves as an adjustment mechanism.

That is, the rail 12 is arranged to extend in a direction perpendicular to the arrangement direction of the clamping columns 11 and is integrally fixed to the base 10 with bolts or the like, and the lower end of the clamping column 11 is attached to the rail 12 by the slide bearing 14. slidingly connected. Further, a threaded rod 13 is disposed extending above and parallel to the rail 12, and its both ends are rotatably connected to the base 10 by bearings 15. It becomes connected.

Further, each of the threaded rods 13 is connected to a drive mechanism 16, as shown in FIG.

That is, a driven gear 16c is connected to the end of each threaded rod 13, and each threaded rod 1 is connected to the base 10 side.
Motors 16a corresponding to No. 3 are mounted and fixed, drive gears 16b are connected to the rotating shafts of each motor 16c, and each of the driven gears 16c is meshed with each of these drive gears 16b, respectively.

In addition, 17 in FIG. 1 is a control device, which includes a control circuit 17a, a calculation circuit 17b, and a measurement circuit 17.
It has c.

That is, at the outer end of each threaded rod 13, a measuring device 17c-1 consisting of a pulse generator is installed.
A signal from the measuring device 17c-1 is detected by the measuring circuit 17c, and a signal corresponding to the number of rotations of each threaded rod 13, that is, the current position of each clamping column 11, is output to the control circuit 17a.

The calculation circuit 17b is composed of, for example, a microcomputer that is generally available on the market, and calculates the amount of drive of each drive mechanism 16 based on necessary data input based on the shape and dimensions of the curved laminated wood to be molded. It is programmed to calculate the number of rotations of the threaded rod 13, and outputs a signal corresponding to the calculated number of rotations to the control circuit 17a.

Further, the control circuit 17a is configured such that the current rotational speed signal value of each threaded rod 13 inputted from each of the measurement circuits 17c matches the set rotational speed signal value of each threaded rod 13 inputted from the calculation circuit 17b. as,
The amount of drive of the drive mechanism 16 is controlled.

Next, the operation mode of the above embodiment will be explained.

First, data necessary for the shape and dimensions of the curved laminated timber to be molded is input into the calculation circuit 17b.

Then, the control circuit 17a rotates each motor 16a, that is, each threaded rod 13, so that the input signal value from each measurement circuit 17c matches the input signal value from the calculation circuit 17b.

As a result, each clamping support 11 is moved along the rail 12 by a predetermined amount, and is arranged on a curved forming line having a predetermined shape.

The clamping struts 11 arranged in the above manner are

Movement in the horizontal direction in FIG. 1 with respect to the base 10 is prevented, and movement in the vertical direction in FIG. 1 with respect to the base 10 is prevented by the threaded rod 13.

(Effects of the Invention) As is clear from the above description, according to the present invention, by simply inputting the data necessary for the shape and dimensions of the curved material to be molded, each clamping support can be aligned to the molding line of a predetermined shape. The clamping columns are automatically arranged along the same line, and each of the arranged clamping columns is immovably connected to the base by a guide and drive mechanism.

Therefore, the present invention has the advantage that the arrangement of the clamping struts can be set extremely quickly and easily.
