Description

Detailed Description of the Invention [Industrial applications]

INDUSTRIAL APPLICABILITY The present invention is a plywood that is handled in a plywood manufacturing process and has some breathability due to back cracking during cutting of veneer, and has unique physical properties that significantly differ in rigidity depending on the fiber direction and the direction orthogonal to the fiber direction. The present invention relates to an improvement of an automatic adsorption supply device for veneer veneers, which is configured to adsorb the topmost veneer veneers from a stack for production and sequentially take them out one by one onto a production line.

[Prior art]

An example of this type of veneer veneer automatic sucking and supplying apparatus for picking up the veneer veneer from the pile and picking it up one by one on the production line is disclosed in, for example, Japanese Patent Laid-Open No. 56-113636.
As described in Japanese Patent Publication No. JP-A-2003-242, in the process of sequentially sucking and stacking the stacked veneer veneers or the like one by one from the uppermost one, the suction port of the suction device connected to the exhaust device is arranged at a certain interval above the thin plate. Near the suction port by partially closing the gap between the suction port and the thin plate from the side with a shielding member and partially cutting off the air flow flowing into the suction port. There is a known method and apparatus for sucking thin plates such as veneer veneer, which is characterized by depressurizing and lowering only the uppermost thin plate. Further, as the accumulated fuel oil adsorption / conveying device, for example, as in Japanese Patent Application Laid-Open No. 57-117431, an adsorption device in which the lower surface of the vertically movable adsorption portion is slightly inclined upward from the center to the side. There is also known a Fooil adsorption transfer device which forms a surface and is provided with a suction port at an appropriate position on the suction surface.

[Problems to be Solved by the Invention]

However, in the above-mentioned conventional technique, in the former case, the purpose is to raise a part of the thin plate by suction in the deposition area, so that the suction surface of the suction device is formed into a flat surface, and the suction port is Since the shielding member that closes the gap between the thin plate and the thin plate is provided only on the lateral side of the suction port, that is, is partially provided when viewed from the entire suction port, the adsorption area becomes small, and the partial area in the deposition area of the thin plate is reduced. There is a problem that only suction suction operation can be performed.In the latter case, the suction-conveyed foam oil itself has some air permeability like a veneer veneer, and the fiber direction is orthogonal to the fiber direction. Unlike a thin plate that has a characteristic that makes the rigidity significantly different, the paper is impregnated with melamine resin and is a weak sheet body with uniform overall rigidity, so the taper surface of the suction head is slightly inclined. The surface of the rubber pad is adhered along the tapered surface, and the lower surface of the rubber pad serves as a suction surface so that the oil can be sucked without breaking. In this case, it is possible to adsorb and convey it because it is a weak sheet material such as Foyle that has an even overall rigidity, but it is somewhat breathable as it is as a veneer veneer, and has a fiber direction and a fiber direction. There is a problem in that it cannot be used for a thin plate suction / conveyance device having a characteristic that the rigidity is remarkably different depending on the orthogonal direction.

[Means for solving problems]

The present invention has an object to solve the above-mentioned problems, and is capable of adsorbing substantially the entire area of the veneer veneer to be adsorbed from the upper surface, and further adsorbing from the front and rear edge portions in the fiber direction of the veneer veneer to be adsorbed to the center. It is characterized in that it comprises a rectangular suction head whose surface is erected as a V-shaped porous suction plate, and an elevating and lowering shield plate which surrounds the entire outer peripheral portion of the rectangular suction head and is vertically movable. It is a thing.

[Action]

The peeling action of two-sheet suction in the veneer single-plate automatic suction supply device equipped with the rectangular suction head, the porous suction plate, and the elevating / lowering shield plate of the present invention is as illustrated in the operation explanatory diagrams illustrated in FIGS. 4A to 4C. In the present invention, the rectangular suction head 2 is moved downward by the lowering operation of an operating mechanism such as a robot (not shown) on the uppermost surface of the laminated veneer veneer 1. The top of the porous adsorption plate 3 and the bottom of the elevating shield plate 4 installed in the rectangular adsorption head 2 are located on the uppermost surface of the laminated veneer veneer 1 with some front and rear edges in the fiber direction outside the adsorption head. And contact them (Fig. 4A). Next, when suction of the veneer veneer 1a on the uppermost surface of the deposition is started by the suction force acting on the rectangular suction head 2, V
The front part and the rear part in the fiber direction are respectively bent upward in a V-shape while pushing up the raising / lowering shield plate 4 loosely mounted on the outer periphery along the adsorption surface of the porous adsorption plate 3 formed in a shape. . Then, the veneer veneer 1b, which is the next most piled-up plate during this pressing and bending, is pressed by the V-shaped top that is the lowermost part of the porous adsorption plate 3 and the rigidity of the veneer veneer 1b itself in the fiber direction. For a moment, both edges are slightly lifted by the suction force leaking from the upper veneer veneer 1a, but the suction force is completely lifted by the air that is rapidly opened and naturally flows between the edge portions between the layers. When the veneer veneer 1b of the next order is cut off, the veneer veneer 1b of the next order is restored to the flat state on the stack again. At this time, the separating operation of the two-sheet adsorption by effectively utilizing the rigidity in the fiber direction is also performed (FIG. ). The adsorption veneer veneer 1 separated into each piece as described above
"a" is an automatic supply for moving a large amount from the deposition to the production line and taking it out in a desired direction by the ascending operation (FIG. 4C) by the operation mechanism of the rectangular suction head 2 and the subsequent horizontal movement operation. The work is repeated repeatedly.

【Example】

An example of the embodiment of the present invention is as shown in FIGS. 1 to 3, in which the thickness to be adsorbed is about 0.5 to 4 mm and the area is 1 m ×
For veneer veneer 1a having a size of 1 m to 1 m × 2 m, front and rear edge portions Ef, E in the fiber direction (arrow Fp)
b is left outside the rectangular suction head 2 for at least 150 to 200 mm or more so that suction force does not act at all,
That is, the suction force does not act on both the front and rear edges of the veneer veneer 1a so that almost the entire area can be adsorbed from the upper surface, and the veneer veneer 1a is orthogonal to the fiber direction (arrow Fr) of the veneer veneer 1a. For example, the rectangular suction head 2 is installed on the actuation mechanism 5 such as a robot so that substantially the entire area extending to the left and right edge portions El and Er can be sucked from the upper surface. Further, a suction device such as a fan or a blower, which is separately provided in the rectangular suction head 2, is connected to the suction port 6, and the suction force of the suction device is controlled to be turned on and off to suck and remove the veneer veneer 1a. It is designed to be automatically performed in sequence. Next, the bottom surface of the rectangular suction head 2 is surrounded by an outer peripheral portion of the rectangular suction head 2, and an elevating shield plate 4 is integrally mounted on the rectangular suction head 2 so as to be vertically movable. For example, for the bottom (top) and the top (both sides) of the V-shaped porous adsorption plate 3 with a loose head of about 5 to 10 mm, the bottom to the top The adsorption veneer veneer 1a adsorbed by the porous adsorption plate 3 is integrally lifted up to the vicinity of (both sides) by the pushing and bending action of the adsorption veneer veneer 1a, and a stable adsorption force is maintained from the beginning to the end.
Further, the rectangular suction head 2 is separately equipped with a computer or the like so that the vertical movement operation and the horizontal movement operation are alternately performed by the operating mechanism 5 such as a robot. On the basis of a command from the control device, the suction veneer veneer 1a is automatically taken out on the production line in the take-out direction of the arrow L, for example. In the figure, 5a is a lifting motor for the operating mechanism 5 such as a robot, 5b is a turning motor, 5c and 5d are horizontal moving motors, 5e is an arm, and 7 is a lifting lifter for the stacked veneer veneer 1.

【The invention's effect】

As described above, according to the present invention, substantially the entire area of the veneer veneer to be adsorbed can be adsorbed from the upper surface, and the adsorption surface is V-shaped from the front and rear edge portions in the fiber direction of the veneer veneer to be adsorbed to the center. Since it is composed of a rectangular suction head erected in the form of a rectangular shaped suction plate, and an elevating and lowering shield plate that surrounds the entire outer peripheral portion of the rectangular suction head and is vertically movable. The suction force can be exerted over almost the entire area of the thin plate as compared with the thin plate suction and conveyance device, and the suction area is large. As a result, a long thin plate can be easily and surely sucked and the suction head It was possible to move efficiently the long thin plate adsorbed on the outside of the deposition area and to efficiently perform the adsorption and conveyance of the thin plate that supplies it in the desired direction at the same time. Veneer veneer fiber Veneer veneer having a certain air permeability, and having significantly different rigidity depending on the fiber direction and the direction orthogonal to the fiber direction, by forming a V-shaped porous adsorption plate from the front and rear edges in the direction to the center. The present invention has various excellent effects not found in the conventional apparatus, such as the fact that the separation operation of two-sheet adsorption that effectively utilizes the characteristics of (2) can be performed together.
