Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for processing intermediate veneers used in plywood production, and more specifically, the present invention relates to a processing device for intermediate veneers used in plywood production, and more specifically, for treating initial top-stripped veneers, so-called top-stripped veneers, which are cut from logs using rotary laces. 4. Relates to a medium veneer processing device for continuously processing width veneers in relation to a rotary lace.

Conventionally, the above-mentioned top-stripped veneers (the front and rear shapes are irregular), core-stripped veneers at the end, narrow-width veneers that are difficult to reel, and veneers that are soft and may become narrower are ,
On the Kosobair installed immediately after the rotary race, it is piled up in one piece by hand or cut into pieces of a certain size, or relatively long pieces are rolled into balls for convenient handling. These veneers are then randomly accumulated in the storage area or on the conveyor on the delivery side, and then these veneers are taken out again and inserted into a veneer cutting machine at a slow speed that is completely different from rotary lace, and the shoulders and products are Measures were taken such as separating the material and then depositing its effective veneer.

Conventionally, the effective veneers deposited as described above are transferred to the veneer supply port of the dryer by a conveyance means such as a lift or a trolley, and the drying direction of the dryer and the fiber direction of the veneers are aligned in the same direction. It was converted and inserted into
In other words, in the past, the veneers that had been randomly stacked had to be picked up from the top by a large number of people and inserted in the same width as the supply width of the dryer. requires at least 15 to 3 pieces of sand,
Furthermore, when there were many narrow veneers, it naturally took even more time to line them up.

As another method, the veneers that have been piled up as described above, or the veneers that have been accumulated while being transferred separately to a tray conveyor, are cut off by a sizing cutting device before being sent to a dryer (roll dryer). After dividing into sized veneers, for example, each narrow veneer treated as described above is transferred in a direction perpendicular to the drying direction of the dryer, and the intervals between each narrow veneer are narrowed so that the veneers are of a certain length. A feeding device (for example, a product name: Pre-Feeder) that feeds the dryer all at once when the temperature is reached has also been used, but this device has drawbacks such as a complicated structure and a large space. Furthermore, none of the following means allows the narrow veneer cut from the rotary lace to be transferred in an orderly manner; This was extremely inefficient, as the curls had to be spread out in between, and the veneers had to be manually taken out one by one from a storage area such as a tray conveyor when feeding the veneers to a sizing cutting device.

The present invention has been made with attention to the above points, and its purpose is to create early veneers, that is, 4 mm width veneers, which are cut from logs using rotary laces, and to make the veneers mutually Automatically winding up onto a reel when the tip end and the end end are in close contact or in a close state and in a continuous state,
Therefore, it is an object of the present invention to provide a processing device for medium-sized veneers, which facilitates the processing operations in the next and subsequent steps, and which allows the processing to be performed extremely efficiently as a whole.

Another object of the present invention is to automatically process the entire process from cutting with the rotary race to the dryer.

Another object of the present invention is to provide an apparatus for processing veneers for intermediate boards, which can prevent damage caused by manual work by eliminating the need for manual work, that is, can process with a high yield, and therefore can significantly reduce costs compared to conventional means. Furthermore, another object of the present invention is to wind a wire such as a filament onto a reel from the back side of a sized veneer, so that the veneers are reliably integrated together without any movement or separation. To provide a processing device for a medium veneer which can also easily unwind a sized veneer.

Next, an embodiment of the present invention that can achieve the above objects will be described in detail with reference to the drawings.

In Fig. 1, A is a rotary race consisting of a pressure plate 1 having a nose bar la and a turret 2 having a blade 2a, B is raw wood, and C is a veneer S cut and delivered by the rotary race A. A carry-out conveyor is shown, and the carry-out conveyor C includes a pulley group 3a provided on a shaft 3, a pulley group 4a provided on a shaft 4, and these pulley groups 3a, 4a.
The belt 5 is made up of a plurality of belts 5 wrapped around each pulley.

D is used for sorting when scrap veneers whose length in the width direction does not meet the desired dimension at the initial stage of cutting are disposed of on the shoulder conveyor 6 provided below, and for transferring other veneers to the subsequent conveyor. A conveyor is shown, with pulley groups 7, 8 and a plurality of belts 9.
The distal end portion thereof is configured to move up and down using the shaft 7a of the pulley group 7 as a fulcrum, for example, using an air cylinder or the like.

In FIGS. 1 and 3, E indicates a conveyor belt, which is rotatably mounted on the shaft 7a of the pulley group 7 (via a bearing).

-IJ- group 10, touch roller group 11a provided on shaft 11, these pulley group 10, each pulley of touch lo-fu group 11a, and a plurality of belts 12 wrapped around between the touch rollers. Reference numeral 13 indicates a pressure roller, which is placed on the pulley groups 7 and 10 described above.
These pulley groups 7 and 10 are provided with a spacing that is the same as or slightly narrower than the thickness of the veneer S, and the veneer S is connected to the pulley group 7 by a spring or air cylinder.
, 10.

That is, when the leading ends of the group of veneers S that are cut and sent out one after another by the rotary race A pass between the pressurized low-hoo 13 and the pulley groups 7 and 10, the driving force of the belt 9 of the sorting Kosobear D is applied. is transmitted via the veneer S to the intermittent conveyor E. As a result, the rotation of the Mata operation conveyor E and the touch roller group 11a is started, and when the end of the veneer S passes the pressure roller 13, the Mata operation conveyor E and the touch roller group 11a are started. The rotation of the roller group 11a is stopped. In other words, a veneer concentrator is constructed in which the leading and trailing ends of the veneers are closely spaced or closely spaced. 14 is a roller disposed above the touch roller group 11a; 15;
indicates a bobbin disposed at the bottom of the touch roller group 11a, and a wire material 16 such as yarn is wound around the bobbin 15.
From this, the guide theory 17, the tip of which is wound around the reel 14 several times via the back surface of the veneer S, is held so that it does not come loose, or an adhesive member 18 such as adhesive tape is used as shown in FIG. It is fixed in place.

The logs B are sequentially cut by the rotary race A, but the veneer S at the beginning of cutting has an irregular front-rear shape, width, etc., and becomes a so-called narrow-width veneer. It is transported by C.

Furthermore, these veneers S are not only uneven in front-to-back shape and width, but also have different intervals between each veneer S, and are conveyed in a so-called discontinuous state. First, among these veneers S, the shoulder veneers whose length in the width direction is less than the desired dimension are discarded on the layer conveyor 6 in the sorting conveyor D section, and the others are discarded as described above. Then, the front and rear of the conveyor E are packed together. At the same time, wire rods 16 such as threads are sequentially paid out from the bobbin 15 as the IJ-rule 4 rotates, and when the leading end of the preceding veneer reaches the point where the touch roller group 11a and the IJ-rule 14 contact, The board is wound around the reel 14 with the feeding direction regulated by the wire rod 16. That is, each veneer is wound around the reel 14 one after another by the wire rod 16 from the back side.
4. In Figures 1, 2, and 4,
F is a reeling deck, 19 is a reel transfer path, 20 is an abbreviation for empty reel transfer, and 21 is a rewinding device for the wound veneer Sa.
As can be seen in the figure, the veneer Sa cut by the rotary race A and wound around the reel 14 is bent so that it is transported together with the reel 14 in the right angle direction, in other words, in the direction displaced by 90 degrees. ing.

That is, the veneer Sa wound on the reel 14 is sequentially transferred to the reel transfer path 19 of the reeling deck F, and then in the unwinding device 21 section, the wire 16 is collected and the veneer Sa is rewound. Sb is transported to the next process by a conveyor 22.

Further, when being rewound as described above, the wire 16 is recovered by the wire recovery device 24 which rotates via the transmission member 23 which rotates synchronously with the unwinding device 21. G is a fixed-length cutting device, E is a dryer, and 1 is a conveyor for insertion into the dryer.The fixed-length cutting device G has a vertically movable cutting blade 25 and a fixed lower receiving blade 26, as shown in FIG.
This is provided between the conveyor 22 described above and the dryer insertion conveyor 1.

In addition, the insertion conveyor 1 has a veneer supply device J that operates to feed the rewound veneer 6b, which has been fed in a direction perpendicular to the insertion direction into the dryer day, to the drying direction on the dryer day.
It includes. That is, the veneer supply device J is composed of a vertically movable pinch roller or a pusher 27 for pushing the edge of the rewound veneer Sb sheep as shown in the figure. Reference numeral 28 denotes a veneer position detection device, which detects the tip of the aforementioned insertion conveyor 1 and detects the cutting blade 25 of the fixed length cutting device G.
the insertion conveyor 1 and the rewinding device 2.
The veneer detection device 28 is electrically connected to stop the rotation of the veneer Sb. Known means, such as a disconnection circuit that sends a disconnection signal in response, may be employed.

In the above configuration, the rewound veneer Sb is transferred to conveyor 2.
2 is transferred in a state where the distance between the ends is narrowed like a band-shaped connected veneer, and the leading edge is transferred as it is to the insertion conveyor 1, and when it becomes the same size as the supply port on the dryer day. The veneer feeder J using a pusher 27 or the like feeds the veneer into the dryer via the communication conveyor 29, or further feeds the veneer from the communication conveyor 29 through the auto feeder 30 into the dryer.

In the embodiment described above, the veneer Sb (the veneer rewound from the reel 14) whose front and rear shapes are irregular as shown in FIG. 5a is fed into the dryer. As shown in the figure, by winding the veneers Sb onto the reel 14 after forming them into sized veneers S, it is possible to increase the number of veneers Sb that are rewound and arranged on the conveyor 1 for insertion into the dryer. That is, Figs. 6 and 7 show examples of this. In the figures, A is a rotary lace, B is raw wood, C is a carry-out conveyor, S is a veneer, and K is a device installed at the end of the carry-out conveyor C. The size cutting device is shown in which a pair of upper and lower rollers 31 and 32 are provided perpendicularly to the conveyance direction of the carry-out conveyor C with a gap that allows the veneer S to be held and conveyed, and the veneer carry-out side of the rollers 31 and 32 is shown. A cutting blade 34 is provided on the outlet circumferential surface of the cutting blade 34, which rotates in the vertical direction about a shaft 33 as a fulcrum, and whose cutting edges alternately touch each other, and a waste conveyor 35 is provided below the cutting blade 34.

Further, on the veneer loading side of the rollers 31 and 32 described above, veneer detectors 36 having contacts 36a such as limit switches or phototubes are provided in multiple rows perpendicular to the unloading direction. If not present, they are connected in parallel in a closed circuit state.

When the tip of the veneer 6 passes the detector 36 and the contacts 36a of all the detectors 36 become the barrier, the front green section cutting circuit 3
When the end of the veneer S passes the detector 36 and even one of the bushing points 36a is closed, a trailing edge cutting signal is generated from the trailing edge cutting circuit 38. Furthermore, these signals are transmitted to an operation controller 3 such as a solenoid valve.
9, thereby actuating an actuating device 40, such as an air cylinder, which substantially rotates the cutting blade 34. The sized veneer S, whose tip and end portions have been cut and removed in this way, includes pulley groups 41, 42 and a plurality of belts 4.
It is conveyed by a conveyor L consisting of three. Since there is a slight gap between the detection position of the veneer S and the cutting blade 34, the cutting width is arbitrarily adjusted by appropriately interposing a timer or other timer in the front and rear edge cutting circuits 37, 38. . Further, the pulley group 10 of the intermittent operation conveyor E as shown in the above embodiment is provided on the shaft 42a of the pulley group 42 of the conveyor L, and the dryer is finally connected through the same process as that of the above embodiment. Sent into Japan. Furthermore, depending on the curled state of the narrow veneer being cut, a guide conveyor may be provided above the carry-out conveyor C, whereby the veneer is regulated into a substantially flat shape, transported, and then rolled up. We sometimes wind up a product proposed and developed by our company that prevents curling from the beginning of cutting. That is, as shown in FIG.
A plurality of sliding bodies 44 with a pressure body 48 such as a coil spring on top
At the tip of the sliding body 44, several blade portions 4 are provided.
A rotary lace A having a normal blade 2a is provided, and the blade part 45a of the low hoover 45 is used to cut the veneer S from raw wood B.
A material in which a front crack 46 is formed and curling caused by a back crack 47 is prevented may be wound by the method and apparatus of the present invention.

Since the present invention is constructed as described above, it is possible to satisfactorily achieve the intended objects as described above.
