Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood pressing device for a finger composer.

[0002]

2. Description of the Related Art FIGS. 9 to 12 show a conventional finger composer (Japanese Unexamined Patent Publication No. H5-24006), in which 1 is a serial form in which wood elements a are sequentially fed by a drive of a roller 2. It is a workbench that is lined up. Glues are applied to both ends (finger parts) of the wood element a by a coating device (not shown) before being sent to the workbench 1, and when the tip of the preceding wood element a reaches the installation position,
This is detected by a detector (not shown) such as a position changeable limit switch and stopped, and then a surplus position of the subsequent required wood element a is cut by a cutter (not shown) that acts, and a plurality of wood elements are cut. It becomes a standard length wood element array A in which a is connected.

Reference numeral 11 in FIGS. 9 and 11 denotes a table provided outside the one side edge of the workbench 1 so as to receive the standard length wood element array A on the workbench 1, and the extension action of the first cylinder 3 The first veneer 4 on the workbench 1 is moved forward in the direction of the table 11 by pushing the wood element a, and the second veneer 6 which is moved forward and backward by the second cylinder 5 is moved from the workbench 1 to the table 11. Transfer to the top.

A stopper plate 12 that moves up and down by the action of a cylinder or the like is provided outside the entire length of one side edge of the table 11 (on the side opposite to the workbench 1). 2 While advancing the veneer 6 to press the fixed-length wood element row A on the table 11 against the stopper plate 12 that has stopped rising, to stop at the pressing position, the upper surface of the table 11 is It is slightly lower than the upper surface of the workbench 1 (as shown in FIGS. 11 and 12).

Further, above the table 11, there is provided a holding bar member 15 which is arranged along the longitudinal direction of the table 11 and which is moved up and down by the action of two parallel third cylinders 14 supported by the arms 13. , This press bar material 15
Within a predetermined range from one end to the other end, a large number of stopper unit 16 groups, in which opposing surfaces are overlapped and juxtaposed, are supported by the holding bar member 15 in a vertically suspended state.

In the above hanging means, each stopper unit 16 is provided with a vertically extending through window 17 from the upper end, and the pressing bar member 15 is penetrated through this stopper window 16. A notch 18 communicating with each other is provided, and a fitting 19 of the pressing bar member 15 is passed through the notch 18.

With the above-mentioned structure, after the wood element row A is fed onto the table 11, the third cylinder 14 is fed.
When the pressing bar material 15 is lowered by the extension action of the stopper bars 16, all the stopper single bodies 16 are also lowered, and the lower end of the stopper single body 16 located immediately above the wood element row A abuts the lower end of the wood element row A during the lowering. Therefore, the stopper unit 16 stops descending, and only the presser bar material 15 continues to descend. Immediately before the completion of the descending of the presser bar material 15, the through window 1
The lower surface of the presser bar member 15 descending inside 7 is the through window 17
Since the stopper unit 16 and the pressing bar member 15 that are in contact with the upper surface of the wood element array A are integrated with each other, the stopper unit 16 presses the wood element array A on the table 11.

On the other hand, since the stopper unit 16 that does not contact the upper surface of the wood element array A descends together to the descending position of the pressing bar member 15, the stopper unit 16 juxtaposed on the extension line of the one end surface of the wood element array A is on the table 11. And descend as shown in FIG.

After that, when the pressurizing device 20 is moved forward to pressurize the other end surface of the wood element array A, the pressurizing device 20 and the parallel stopper unit 16 lowered to the final position are used for the wood element array A.
Is clamped and tightened. That is, the opposite ends of the wood element a are adhered by the adhesive paste to form wood having a set length.

When the pressing bar member 15 is lifted by the contracting action of the third cylinder 14 after the completion of the pressing, the stopper single body 16 serving as a stopper first rises, and then the notch of the stopper single body 16 on the wood element row A. The engaging pieces 10 on both sides of 18 engage with the pressing bar member 15, and the stopper simple substance 16 rises.

The pressurizing device 20 has a fourth cylinder 21.
And a pressing member 22 that advances and retreats by the action of the fourth cylinder 21, and the pressing device 2 for the pressing bar member 15
The stopper unit 16 at the end opposite to 0 is prevented from slipping off from the end of the pressing bar member 15 by the engaging member 23.

[0012]

In the above-mentioned prior art, among a large number of stoppers alone, one that does not contact the upper surface of the wood element row descends below the wood element row to serve as a stopper when the wood element row is pressed. Therefore, even if the length of the wood element row is changed, the position of the stopper will change automatically without any operation,
Although there is an advantage that the troublesome work of stopping the operation of the machine and changing the position of the stopper is unnecessary, when the end surface of the wood element row is pressed by the pressurizing device, the pressure causes the stopper unit to be compressed. Therefore, the stopper may be pushed obliquely, and the stopper simple substance 16 which is a part of the large number of stoppers may be lifted in an arc shape as shown in FIGS.

When the stopper unit is lifted in an arc shape in this manner, when the short element unit a as shown in FIG. As shown in FIG. 14, the wood element row a of the portion where the wood element row a is lifted is connected by the force that tries to lift the stopper unit 16 in an arc shape, and is diagonally connected to cause a defective product.

Further, since the stopper unit 16 is pushed diagonally, it becomes difficult to transmit the pressing force for connecting the wood element row A straightly, which causes bending of the connected product itself, and the stopper is lifted in an arc shape. As a result, the wood pressing force is weakened, which causes problems such as poor connection of the finger connection parts.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device for preventing the stopper unit from being lifted in an arc shape when the wood element row is pressed in order to solve the above problems.

[0016]

In order to solve the above problems, the present invention is provided above a table on which a row of wood elements is placed.
A pressing bar member that is parallel to the longitudinal direction of the table and that is moved up and down by the driving means is provided, and a plurality of stopper units are moved up and down with respect to the pressing bar member within a predetermined range from one end to the other end of the pressing bar member. It is supported in a freely suspended state, and
An engaging member is provided so that the stopper alone does not come off from one end side of the pressing bar member, and a pressing and pressing device for the wood element row on the table is provided outside the other end of the pressing bar member of the table. In the finger composer, a structure is provided in which a stopper single unit pressing device including a stopper single unit pressing member on one end side of the stopper single unit row and a receiving member on the other end side of the stopper single unit line is provided.

[0017]

Since the present invention has the above-mentioned structure, when a regular length of wood element row is supplied on the table similarly to the above-mentioned known apparatus, and then the presser bar member is lowered, all the presser bar members are removed. The stopper alone goes down. When the lower end surface of the stopper alone comes into contact with the upper surface of the wood element row, the lowering of these stopper alone is stopped and the lowering of only the pressing bar member continues.

At this time, the stopper alone contacting the upper surface of the wood element row and the lower surface of the press bar material are connected and integrated immediately before the end of the descent of the press bar material while continuing the descent, so that the upper surface of the wood element row is integrated. A downward pressing force (to the extent that buckling is prevented) acts on the stopper via the stopper alone.

On the other hand, since the stopper alone that does not contact the upper surface of the wood element row descends to the descending position of the pressing bar member,
A single stopper is arranged in parallel outside the one end face of the wood element row. When this state is reached, the stopper unit pressing device operates to press the stopper unit row by the pressing member and the receiving member so that each stopper unit is integrated to prevent arc-shaped lifting.

After that, when the pressurizing device is advanced to pressurize the other end face of the wood element row, the wood element row is pinched and clamped by this pressurizing device and the parallel stopper alone lowered to the final position. . That is, in the wood element array, the opposite ends are bonded and integrated by the adhesive glue to form the wood of the set length.

When the pressing bar material is lifted after the completion of the pressing, the stopper alone, which has been acting as a stopper, goes up first, and then the stopper alone on the wood element row goes up and returns to its original position.
