Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing plate-like products from wood rod-like strips elongated in the direction of the fibers obtained by processing veneer waste. By using a forming path with a narrow cross section, in the vertical state, a layer is formed with an appropriate head height using a receiving plate provided in the forming path, and after forming this layer, the forming path is rotated horizontally and inserted between press plates. The structure is such that the layered material is placed on a press plate, and with such a simple structure, it is possible to convert this kind of bar-like strip into a plate-like material with uniform orientation, uniform thickness, and uniform density. The present invention provides a device that can be manufactured.

The rod-shaped strips produced in the apparatus of the present invention are made by converting veneer waste A as shown in FIG. 1A into rod-shaped strips B elongated in the fiber direction as shown in FIG. 1B, Plywood scrap A is generally used as the core board of plywood, and its thickness is 1
．． It is about 3 mm to 4 mm, and the rod-shaped strip B obtained by processing this is 1.3 mm x 1.3 mm to 1.3 mm x 4 mm.
It is a rod-shaped strip with a cross section of about 30 cm to about 90 cm in length.

It is extremely difficult to manufacture plate-like products with uniform orientation, uniform thickness, and uniform density from such rod-like strips.
For example, if forming is performed in a horizontal state, such as in hardboard or particle board, it is extremely difficult, almost impossible, to achieve uniform thickness and density even if the directionality is uniform.

The present invention succeeded in forming this in a vertical state with a narrow cross section based on the thickness of the product, and further simplified the equipment by pressing in a horizontal state.

The apparatus of the invention will be explained below by means of embodiments shown in the drawings.

1 and 2 are molded plates, and the two molded plates 1 and 2 are made of relatively thin and highly rigid metal plates or synthetic resin plates,
The molded plate 1 has supporting members 5 and 6 attached at both end portions 1a and 1b to a pair of left and right swinging rods 3 and 4.
The molded plate 2 is clamped and fixed by
a and 2b are clamped and fixed by support members 5 and 6 attached to rocking rods 3 and 4, and the molding plates 1 and 2 are arranged so that the opposing molding surfaces 1' and 2' are substantially parallel to each other and at a predetermined distance. D, and are surrounded by the inner surfaces 5a, 5'a, 6a, 6'a of the two molded plates 1 and 2 and the supporting members 5, 5', 6, 6', respectively. A molding path F is formed by the space.

The dimensions of the forming path F are set according to the dimensions of the plate-like object to be molded, and the predetermined interval D, which is the dimension of the thickness of the molded product, is set to approximately 4 to 5 times the thickness of the product, and is perpendicular to the fibers of the molded product. The size is set to a size sufficiently commensurate with the width dimension W in the fiber direction and the length dimension L in the fiber direction.

The predetermined interval D is such that when a layered body of rod-like strips B formed with this dimension is pressed with a pressure of 15 to 25 kg/cm2, an ideal product with a specific gravity of 0.5 to 0.7 can be obtained. .

The receiving plate 7 is supported by rods 10 and 10' of hydraulically actuated cylinders 9 and 9' attached to the swinging rods 3 and 4 via support arms 8 and 8' attached to both ends thereof. By the operation of 9',
It reciprocates within the forming path F between the input end P and the end P', and its receiving surface 7a is the cross section of the forming path F (horizontal when the forming path F is vertical as shown by the solid line in FIG. 2 or 4). The forming path F has almost the same shape and area as the cross section) and is in a vertical state.
This is to catch the bar-shaped pieces B falling into the container.

Further, as will be described later, the receiving plate 7 also serves as a stopping function when the bar-like strips B formed in a layered manner are placed on a press plate in the forming path.

The receiving plate 7 does not need to move rapidly in the forming path, and the cylinders 9 and 9' that operate it are moved by hydraulic pressure, and an oil motor or the like is used as the driving source, since the receiving plate 7 does not need to move rapidly in the forming path and can be stopped at an appropriate position. Perform these operations using .

The forming path is constructed so that it can turn as shown by an arrow R into forming path F in a substantially vertical state shown by a solid line in FIG. 2 or FIG. 4 and forming path F' in a substantially horizontal state shown by a dotted line.

This turning movement of the forming path is performed by the swinging of the swinging rods 3 and 4, and the picking up of the swinging rods 3 and 4 is achieved by a shaft 12 fixed to brackets 11 and 11' attached to one side of each.
The focus will be on

That is, the shaft 12 is supported by bearings 14, 14' attached to the truck 13, and arcuate racks 15, 15' are fixed to the other side of each of the swinging rods 3 and 4. , 15' are engaged with pinions 16, 16', which are fixed to the shaft 17, and the pinions 16, 16' are fixed to the shaft 17.
7 is supported by bearings 18, 18' attached to the truck 13, and the rotation of the shaft 17 rotates the pinions 16, 16', and this rotation moves the racks 15, 15' to move the swinging rods 3 and 4 around the shafts. 12 as the center.

The shaft 17 is driven to rotate by passing a chain 22 between a chain wheel 19 fixed to the shaft 17 and a chain wheel 21 attached to the shaft of a reversible motor 20, and driving the reversible motor 20 in forward and reverse rotation.

Below the truck 13 is a shaft 24 supported by a bearing 23.
, 24' are equipped with rollers 25, 25'.
5 and 25' roll on the rails 26, and as shown in FIG.
Move back and forth between the position ′.

The reciprocating movement of the trolley 13 is achieved by passing the rotational force of the shaft of a reversible motor 27 attached to the trolley 13 through a chain wheel 28 attached to the motor shaft and a chain wheel 29 attached to the shaft 24. This is done by rotating the rollers 25 in forward and reverse directions.

The press section 31 is composed of upper and lower press plates 32 and 32', and as shown in FIG.
' is advanced to the position of the carriage 13' shown by the dashed line on the carriage 13, the upper and lower press plates 32 and 32' are in the open state.
This is the position where the forming path F' is just inserted between them.

Further, as shown in Fig. 3, the press plate 32, 32' has cutting arrow portions 33, 33', 34, 34 at both ends of the forming path in the insertion direction.
' are provided, and when the forming path F' is inserted between the press plates, the support members 5.5' and 6.6' are exactly in the notch portions 33 and 33.
', 34, and 34', and is constructed so that the forming plate 1 of the downward forming path in the horizontal state rests on the upper surface of the lower press plate 32'.

The carry-in conveyor 35 has a forming path F with its rear end Q being vertical.
The rod-shaped strip B is placed close to the upper side of the carry-in end P of the molding plate 1, and from the position of the rear end Q, the bar-shaped strip B is aligned with the molding surfaces 1' and 2' of the molding plates 1 and 2 so that its longitudinal direction is approximately horizontal. The orientation and the direction of conveyance of the strips conveyed on the conveyor are set so that they fall in parallel.

It should be noted that an adhesive is applied in advance to the rod-like strips B conveyed by the carry-in conveyor 35, and an appropriate adhesive such as a thermosetting adhesive such as a urea resin adhesive or a phenol resin adhesive is used as the adhesive. .

The manner of implementing the present invention will be explained below.

In the apparatus of the present invention, the fiber direction, that is, the longitudinal direction, of the rod-like strips B is oriented in the width direction of the vertical forming path F, and the longitudinal direction is as shown in FIGS. 2 and 4.
In the figure, the direction is perpendicular to the paper surface, and in FIG. 5, it is the left-right direction.

In this way, the rod-like strips B are oriented in the vertical forming path F so that the longitudinal direction thereof is perpendicular to the plane of the paper in FIGS. 2 and 4, and in the left-right direction in FIG. 5 to form a layered structure. Therefore, the bar-shaped strips B are transported by the carrying-in conveyor 35.
When conveying, the directionality is oriented in the direction perpendicular to the plane of the paper in FIGS. 2 and 4, and in the left-right direction in FIG. The density of the strips in this direction is almost equally conveyed, and when they fall from the rear end Q to the carry-in end P of the vertical forming path F, the longitudinal direction is the forming surfaces 1' and 2' of the forming plates 1 and 2. Set the transport direction of the conveyor so that the material falls parallel to and horizontally.

The implementation procedure will be explained with reference to the drawings shown in FIG.
is vertical and the receiving plate 7' has its receiving surface 7 near the carry-in end P.
'a and the rear end Q of the carry-in conveyor 35 is positioned such that the head difference is a suitable height H.

In this state, the carry-in conveyor 35 is run, and the rod-like strips B fall from the rear end Q onto the receiving surface 7a of the receiving plate 7', thereby starting to form a layer.

When this layer formation begins, the cylinder 9 as shown in figure b
, 9' are operated to move the receiving plate 7 downward, but this movement is carried out so that a suitable height difference H is maintained between the upper surface of the bar-shaped strip B placed on the receiving plate 7 and the rear end Q, and the strip is moved downward. Preventing directionality.

Even if the bar-shaped strip B is dropped with an appropriate head H, it may not fall horizontally due to differences in the longitudinal shape of the strips or differences in specific gravity. A means for aligning the direction of the strips by inserting a push plate or the like from above the carry-in end P of the channel F is provided.

As described above, since the apparatus of the present invention drops the bar-shaped strips B onto the forming path in the vertical state with a predetermined relatively narrow interval D in the vertical state, the strips are formed in a uniform layer between the intervals D. , and the direction will also be aligned.

Figure C shows a state in which the layered body continues to be formed in this way, and the receiving plate 7 reaches the position of the end P' of the forming path, and a layered body c having a widthwise dimension W is formed in the forming path F. When the formation of the layered body c having the dimension W is completed, the carry-in conveyor 35 is stopped to stop the bar-like strips B from falling, and the reversible motor 20 is activated to rotate the pinions 16 and 16', and the rack 1
5 and 15', the swinging rods 3 and 4 are pivoted to shift the forming path from the vertical state to the horizontal state as shown in figure d.

When the forming path becomes horizontal, the reversible motor 27 is activated,
The carriage 13 is moved forward to the position indicated by the carriage 13', and the forming path F' is moved to the upper and lower press plates 32.3 as shown in figure e.
Insert between 2'.

When the insertion of the forming path between the press plates is completed, the reversible motor 27 is driven in reverse to move the truck 13 backward as shown in figure f.
9' is also operated to advance the receiving plate 7 in the forming path F' (movement to the left in FIG. 2), and the forward speed of this receiving plate 7 and the backward speed of the trolley 13 are set to be the same. Then, the receiving plate 7 is stopped at the same place on the press plate between the press plates, and the receiving plate 7 acts to correct the movement of the layered body c against the movement of the forming plates 1 and 2. The remaining reservoir is placed on the lower press plate 32'.

In this case, until the entire amount of the layered body c is placed on the press plate 32', that is, the receiving surface 7a of the receiving plate 7 is
The forming plate 1 is relatively thin and, as mentioned above, when inserted between the press plates in the forming path, the forming plate 1 moves forward and backward until it reaches near the position of the carry-in end P of the press plate 3.
2', the layered body can be transferred smoothly from the forming plate to the press plate without deforming the shape of the layered body.

When the layered material c has been placed on the press plate, the cart 13 moves back further, and when the cart 13 stops at its original position as shown in figure g, the reversible motor 20 is reversed and the forming path is leveled. The receiving plate 7 is also stopped at a predetermined position close to the carry-in end P shown in Figure A in preparation for the next layer forming.

On the other hand, when the forming path is separated, the press section 31 is activated, and the upper and lower press plates 32, 32' heat and press the layered body c to form it into a plate-shaped object.When the pressing is completed, the plate-shaped object is released from the other side of the press plate. is taken out and transferred to the next process.

In this case, the timing of the pressing time of the press and the time from the forming of the forming path to the turning to the horizontal state are set so as to match the timing, so that highly efficient work can be carried out.

In the examples, explanations have been given of a single-stage press with one set of forming paths. For example, it is also possible to have a plurality of forming paths with forming surfaces almost parallel to the swinging rod, and to use a press with the number of stages corresponding to the forming path. The present invention also includes configurations that allow for higher volume production.

As described above, the apparatus of the present invention does not perform layer formation on a wide surface of the product in width and length, but performs layer formation on a narrow area of product thickness in a vertical state and with an appropriate height, so that it is possible to form a layer in a vertical manner. When forming a layer from a material, it is possible to achieve extremely accurate thickness density and fiber direction with a simple device, and it is also possible to transfer a product formed in a vertical state to a horizontal state without the layer state collapsing. Since it is constructed to be pressed, it is possible to use a pressing device for hard boards, particle boards, etc., which have been generally employed in the past, and there is an advantage that the pressing device can be simplified.
