Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for applying adhesive to a veneer.
- At the same time, a doctor roller (4) is arranged on the side of the coating roller (3) so as to be in contact with the coating roller (3). An adhesive stopper plate (5) is arranged so as to straddle both sides of the zero-rule (4) and slide into contact with the side surfaces of both zero-rules (3H4), and the lower end surface of the adhesive stopper plate (5) is An inclined surface that slopes downward toward the outside (6
) and below the adhesive stopper plate (5) above the passing position of the veneer (1) passed between the pinch o-ru (2) and the applicator o-ru (3). The adhesion side support for a spretzer is characterized in that the adhesion side support is provided with a plate ( ).

Thin veneer obtained by slicing raw wood with a slicer (1
) is first loaded on a lifter (8) as shown in Figure 1, and then sucked into an autofeeder (9) made of this single plate (11 is a neem chamber that moves back and forth in the horizontal direction). The sheets are transferred one by one to the Ba+Neem Koshibea TI (e).The Ba+Neem conveyor 0[1 has a large number of suction ports (11) as shown in Fig. 2, and the Ba+Neem conveyor (The veneer (1) is conveyed while being suctioned onto the Bar+ Neem Koshi Bear+10+ by the suction power of the Bar + Neem Chamber □ which is installed on its own.

Further, a position correction guide vehicle is provided on the Bashi Neemukushi Bear +101 to prevent the supply position to shift to the thread term. This is because when applying multi-color coating with Sprayer A, misalignment of the veneer (1) becomes a problem. In this way, the veneers (1) are fed one by one to the spray term, the adhesive I is applied, and the veneers (1) are pasted onto plywood or the like.

As shown in Figure 3 (6) (b), the spray term is the upper and lower coating rollers (3), pinch rolls (rolls) and coating rollers (3).
3) and the doctor roll (4) in contact with the coating roll (3) and the doctor roll (4), so as to straddle both sides of the coating roll (3) and the doctor roll (4), and to make sliding contact with the sides of both rolls +3) +41. A pair of adhesive stopper plates +51 (6) are provided on the handle, and an adhesive opening is made in the area surrounded by the pair of adhesive stopper plates +61 +51, the coating rule (3), and the doctor rule (4). Umbrella → is stored, and adhesive (+4) is applied to the veneer (1) supplied between the coating 〇-ru (3) and the pinch, 0-ru (!).In this ζ, When using multicolored adhesive □ agent 04), multiple spray terms are used on the front and back or on the left and right as shown in Figure 3 (,) (b).
3) and the side of the doctor wheel (4) and the adhesive stopper plate (
6), the adhesive shaft gradually flows down, and the adhesive drips down from the bottom surface of the adhesive stopper plate (6) and adheres to the surface of the veneer +1+ in areas where this adhesive should not be applied. death,
This may cause defects. Therefore, as shown in FIG.
), but in this case, the adhesive is coated with a coating agent (3) or a doctor agent (4).
The adhesive side supporter cannot be properly received by the plate (7) because it drips down close to the side surface of the adhesive side supporter. If it is placed too close to the side of 4), the adhesive (14) flowing along the side of the applicator holder (3) and doctor holder (4) will be rubbed by the plate (7). This adhesive (1
4) would be allowed to adhere to the surface of the veneer (1) in areas where it should not be applied, which would cause more inconvenience.

The present invention has been made in view of the above points, and is capable of preventing adhesive from being clouded onto the veneer from the side of the applicator roll or doctor roll, and efficiently recovering the adhesive. The adhesive side supports of the sprayer are intended to provide a device.

The present invention will be explained in detail below using examples. FIG. 6 shows an embodiment of the present invention, in which the lower surface of the adhesive stopper plate (6) is formed into an inclined surface (6) that tilts downwardly toward the outside, and the adhesive stopper plate (5) It has a pointed lower end. In this product, the adhesive (14) that gradually flows and falls between the side of the applicator 0-ru (3) and the dog 9-0-ru (4) and the inner surface of the adhesive stopper plate (SL) is an adhesive. The adhesive flows from the inner surface of the stopper plate (5) to the inclined surface (6), and the adhesive side holder is connected to the plate (
7). In this one, the adhesive stopper plate (6)
Since the lower surface of the adhesive stopper plate (6) is an inclined surface (6), the adhesive I hardly drips down from the center of the lower surface of the adhesive stopper plate (6), and is always on the inclined surface (6). Since the adhesive 04 drips from the lower end of the outer surface of the adhesive stopper plate (61), the adhesive 04 drips down from the lower end of the outer surface of the adhesive stopper plate (5). ) is not required to be too close to the coating roller (3) or the doctor roller (4).

By the way, when supplying the veneer (1) to the spray term, as shown in FIG.
When correcting the misalignment of the veneer (1), as shown by the line M in Figure 2, the corner of the position correction guide (the veneer 11 when fed between ls and H) is If the veneer 11) is sent in a vertically sagging state, it is likely that the veneer 11) will hit the vertical piece of the position correction guide and the vertical piece of the do I, causing a crack. It cannot be corrected, and in this case, the veneer (1) breaks and cracks when passing the veneer 10 between the sprayer A coating o-ru (3) and the pinch o-ru (2). A problem arises.

A position correction guide H that has been improved to solve these problems is shown in FIGS. 11 and 8. With this, the position correction guide (I
An inclined guide piece Oη is formed between the vertical piece (161) and the lower horizontal piece (161) in the range from the end of the side where the veneer (1) is supplied to near the end, and the inclined guide A blade groove On with a triangular cross section is formed between the lower surface of the single plate Oη and the upper surface of the veneer (+Q).
The position correcting kite H is held down by the presser foot, which is used by adjusting the spring force according to the plate thickness and Young's modulus of 1). The groove width 1h1Jil of the kite groove (III) is set so that the position correction guide (l:1) is large at the beginning and gradually becomes smaller toward the end, and the opening angle θ of the guide groove end is
11θg is set so that it is small at the beginning of the position correction guide I and then gradually increases toward the end. However, when correcting the position of the veneer (1) using the position correction guide 01 formed in this way, the veneer (1) whose position has shifted is moved to the inclined guide of the guide groove 01, as shown in Figures 2 and 8. The position of the veneer +11 is corrected by being guided by the slanted guide piece aη of the guide groove (11).

In addition, the adhesive (I4) in Spretzator A is heated up due to the influence of the surrounding temperature and the frictional heat generated when the coating roller (3) and doctor roller (4) are rotated, and it gels over time. There is a risk that the fifth
Adhesive 04-? Directly put the cylinder (1
Cooling is performed by blowing cold air from 1 to 1, but in this case, cooling is performed partially, and the adhesive (14) has a temperature that differs partially. Board (1) - Adhesive (1
No. 4 was good, but unnecessary parts were formed, which caused variations in bonding conditions and caused poor bonding. Figure 9 shows a solution to this problem, which is achieved by passing cooling water through the axes of the applicator roll (3) and doctor roll (4) from one side with a water pipe and discharging it from the other side. Heat dissipation fins @υ are provided on the adhesive stopper plate (6) which cools the entire roll F31+41 and slides into contact with the side surface of both rolls F31+41 with a presser. In this case, the entire spooler is cooled by the respective cooling effects of the cooling water and the heat sink @υ, and the application roll (3) and doctor roll (4) and the adhesive stopper plate il+ are cooled when the rolls are rotating. It can prevent the adhesive (14) from being heated due to the frictional heat between the two and the adhesive (14).
4 can be cooled entirely.

As mentioned above, the present invention is applied to the upper part of the piston oil.
When the doctor roller is placed, the doctor roller is placed on the side of the applicator roll so that it comes into contact with the applicator roll. An adhesive stopper plate is arranged so as to make sliding contact, and the lower end surface of the adhesive stopper plate is set to an inclined surface that slopes downwardly toward the outside, and the veneer is passed between the pinch roll and the coating roller. Since the adhesive receiver is made up of a plate placed below the adhesive stopper plate above the passing position of the There is almost no dripping from the center of the bottom of the adhesive stopper plate, and it always flows straight along the slope to stop the adhesive! The adhesive tray must be able to catch the adhesive dripping from the lower edge of the outer surface of the adhesive stopper plate. To prevent the adhesive from dripping from the bottom edge, place the tray on an applicator roll or doctor.
There is no need to place it close to the cable.
