The adhesive coating apparatus of the first embodiment includes a base 1, a coating unit 2, a transport unit 3, and a control unit 4.
On the base 1, the coating unit 2 and the transport means 3 are installed.
The workpiece 5 that is the object to be coated with the adhesive 6 is conveyed by the conveying means 3.
The coating unit 2 applies the adhesive 6 to the workpiece 5 transported by the transport unit 3.

〔work〕
As described above, the workpiece 5 is an object to which the adhesive 6 is applied, and is a siding material in this example. In this example, the workpiece 5 is a siding material for performing a cornering process, and an end surface which is one side of a rectangle is cut at 45 degrees. The end face cut at 45 degrees is the application surface of the adhesive 6.

〔adhesive〕
As the adhesive 6, for example, a one-pack type urethane adhesive can be used. In this invention, it is not the meaning which prevents using the adhesive agents 6 other than the above as the said adhesive agent 6.

[Coating unit]
3 and 4 are diagrams for explaining the coating unit 2.
FIG. 3 shows a state where application is possible with the lid open. (A) is the state seen from above, (B) is the state seen from the side, and (C) is the state seen from the front.
FIG. 4 shows a standby state with the lid closed. (A) is the state seen from the front, (B) is the state seen from the side.
In any case, for the convenience of understanding, a cross-section is partially shown and described.

  The coating unit 2 includes a storage tank 11, a coating roll 12, and lid means 13.

The storage tank 11 stores the adhesive 6.
The application roll 12 rotates with the roll surface in contact with the adhesive 6 stored in the storage tank 11.
The lid means 13 opens and closes the opening portion of the storage tank 11.

[Reservoir]
In this example, the storage tank 11 is a square box shape having an open portion on the upper surface. In the internal space of the reservoir 11, the coating roll 12 is rotatably supported. Adhesive 6 is stored in the storage layer 11 so that the coating roll 12 is immersed in about half.

[Coating roll]
The application roll 12 is a cylindrical roll formed of an elastic material such as rubber. The coating roll 12 has a shaft 15 attached to a portion that becomes a cylindrical axis. The shaft 15 is provided on both surfaces corresponding to the bottom surface and the top surface of the cylindrical application roll 12. The application roll 12 is arranged so that the shaft 15 extends in the front-rear direction.

  The shaft 15 of the coating roll 12 passes through the wall surface of the storage tank 11. The application roll 12 is pivotally supported in the storage tank 11 so that the shaft 15 is supported by a bearing member 16 provided outside the storage tank 11. A shaft seal 17 is provided in the gap between the shaft 15 penetrating the wall surface of the storage tank 11 and the wall surface.

The coating roll 12 is immersed in the adhesive 6 stored in the storage tank 11, and the roll surface is in contact with the adhesive 6. When the coating roll 12 rotates about the shaft 15, the roll surface is carried upward.
In this state, the application surface of the workpiece 5 is brought into contact with the roll surface, and the application roll 12 is rolled. Thereby, the adhesive 6 adhered to the roll surface of the application roll 12 is transferred to the application surface. In this way, the adhesive 6 is applied to the workpiece 5.

  A blade 18 is provided in the storage tank 11. The blade 18 is arranged such that the tip thereof forms a slight gap with the roll surface. The blade 18 adjusts the amount of the adhesive 6 that adheres to the roll surface and is carried upward when the coating roll 12 rotates. That is, the excess adhesive 6 adhered to the roll surface is scraped off by the blade 18, leaving a uniform amount on the roll surface, so that the adhesive 6 can be uniformly applied to the workpiece 5.

[Cover means]
The lid means 13 includes a lid member 21 and an opening / closing unit 22.

  The lid member 21 opens and closes the open portion of the upper surface of the storage tank 11 by the operation of the opening / closing unit 22. When the open part of the storage tank 11 is closed by the lid member 21, the curing of the internal adhesive 6 can be delayed. In the state where the lid member 21 is opened and the opening portion of the storage tank 11 is opened, the adhesive 6 is applied to the workpiece 5 described above.

  The opening / closing unit 22 includes a moving arm 23, a link arm 24, and a cylinder 25.

The moving arm 23 is fixed so as to protrude rearward from the lid member 21.
The link arm 24 has a pair of front and rear parallel arms, and a pair of front and rear arms are provided on the left and right, respectively. An upper end portion of the link arm 24 is attached to the moving arm 23 so as to be able to perform a joint operation. A lower end portion of the link arm 24 is attached to a base portion 26 provided on the base 1 so as to be capable of articulating.
The cylinder 25 rotates the link arm 24 fixed to the cylinder rod 25A back and forth as the cylinder rod 25A advances and retreats. As a result, the moving arm 23 moves forward and backward, and the lid member 21 attached to the moving arm 23 moves forward and backward.

The opening of the lid means 13 means that the lid member 21 is moved backward by the operation of the opening / closing unit 22 to open the open portion of the storage tank 11. The closing of the lid means 13 means that the lid member 21 is advanced by the operation of the opening / closing unit 22 to close the open portion of the storage tank 11.
That is, when the lid member 21 is advanced toward the storage tank 11 by the opening / closing unit 22, the open portion of the storage tank 11 is closed by the lid member 21. When the lid member 21 is moved backward by the opening / closing unit 22, the opening portion of the storage tank 11 is opened. Opening / closing of the lid member 21 by the opening / closing unit 22 is controlled by the control means 4.

[Conveying means]
FIG. 5 is a view for explaining the conveying means 3. Both are seen from the side. (A) is a state before chucking the workpiece 5, (B) is a state where the workpiece 5 is chucked, and (C) is a state where the chucked workpiece 5 is conveyed and the adhesive 6 is applied. For convenience of understanding, a cross-section is partially shown for explanation.

  The transport means 3 includes a transport rail 31, a carry 32, an arm 33, a receiving plate 34, and a chuck 35.

  The transport rail 31 is attached to a support column 7 disposed on the left and right rear sides of the base 1 via a beam member 7A. The transport rail 31 is installed horizontally so as to follow the direction in which the coating roll 12 rotates.

  The carry 32 is slidably attached to the transport rail 31. A carry 32 can reciprocate along the transport rail 31. The movement of the carry 32 is controlled by the control means 4.

  Two arms 33 are paired, and are provided so as to extend downward from the carry 32. The pair of arms 33 are arranged at a predetermined interval in the direction in which the transport rail 31 extends (that is, the direction in which the carry 32 reciprocates).

  The receiving plate 34 is for placing the work 5 to be chucked. The receiving plate 34 is pivotally supported on a shaft 33 </ b> A provided so as to penetrate the lower ends of the pair of arms 33. Thereby, the receiving plate 34 can be rotated in the vertical direction at the lower end portions of the pair of arms 33. Specifically, the receiving plate 34 rotates about the shaft 33A between a chucking position where the receiving surface is horizontal and an application position where the receiving surface is obliquely below 45 degrees.

  At the chucking position, since the workpiece 5 is placed on the receiving plate 34 whose receiving surface is horizontal and chucked, the rotation of the receiving plate 34 is stopped. At the application position, since the adhesive is applied to the chucked workpiece 5, the rotation of the receiving plate 34 is stopped.

  A positioning projection 34 </ b> A for positioning the workpiece 5 is provided on the receiving surface of the receiving plate 34. When the workpiece 5 is placed on the receiving surface of the receiving plate 34, the rear end surface of the workpiece 5 (on the side opposite to the application surface) is brought into contact with the positioning protrusion 34A. In this state, when the receiving plate 34 is inclined to the application position, the application surface of the workpiece 5 is positioned at a height that allows rolling contact with the roll surface of the application roll 12.

  The chuck 35 includes a rotating arm 35A that is pivotally supported by the shaft 33A and a presser plate 35B that presses the workpiece 5. The chuck 35 presses and fixes the work 5 placed on the receiving surface of the receiving plate 34 from above.

  At the chuck position where the receiving plate 34 is horizontal, the chuck 35 presses and fixes the workpiece 5 placed on the receiving plate 34. Thereafter, the receiving plate 35 is rotated to an application position at 45 degrees obliquely below. In this state, the control means 4 controls the carry 32 moving along the transport rail 31. At this time, the lid member 21 passes over the open storage tank 11, and the application surface of the work 5 rolls into contact with the roll surface of the application roll 12. The adhesive 6 attached to the roll surface of the application roll 12 is transferred to the application surface of the workpiece 5.

[Control means]
The control means 4 controls the opening and closing of the lid means 13.
That is, the control means 4 opens the lid means 13 while the adhesive 6 is applied to the work 5 as the application object by the application roll 12, and the adhesion to the work 5 by the application roll 12. The lid means 13 is controlled to be closed while the agent 6 is not applied.

The control means 4 controls the conveyance of the workpiece 5 by the conveyance means 3.
That is, the control unit 4 controls the conveyance unit 3 to convey the workpiece 5 that is an application target with respect to the roll surface of the application roll 12.

(3) Application As shown in FIG. 6, the lid member 21 is moved backward by the opening / closing unit 22 to open the open portion of the storage tank 11. Next, the transport unit 3 moves the chucked workpiece 5 in a direction along the rotation direction of the coating roll 12. At this time, the lid member 21 passes over the open storage tank 11, and the application surface of the work 5 rolls into contact with the roll surface of the application roll 12. The adhesive 6 attached to the roll surface of the application roll 12 is transferred to the application surface of the workpiece 5.

[Effects of First Embodiment]
