Description

Detailed Description of the Invention The present invention involves holding and rotating the left and right butt ends of a raw material raw material using a veneer lace, etc., and cutting a cutting blade that extends over the entire length of the raw material into the outer circumferential surface of the raw material to cut a wide sheet-like thin veneer veneer. At this time, the veneer, which is produced in a continuous strip as the cutting progresses from the raw wood, is wound onto a reel just like a cloth, and then the rolled ball is rewound and sent to a drying device, etc. This is related to rewinding.

Most conventional veneer lace cutting, winding, and unwinding devices are shown in Figure 1P1. The conventional device will be explained below. Figure 1 is an overall side sectional view of the veneer cutting production line.

1 is a vegnalace, and the left and right end faces of the log 2 are held between spindles and rotated in the direction of arrow A.

On the other hand, a turret 4 equipped with a cutting blade 3 and a pressure bar body 6 equipped with a pressure bar 5 above the turret.
are advanced together with a feed screw (not shown) onto the raw wood to produce the veneer P. Reference numeral 7 denotes an unloading conveyor comprised of a plurality of belts installed in the r direction of the veneer lace cannon 4, and is used to unload the veneer from the veneer lace in the direction of arrow B. Reference numeral 30 denotes a winding and unwinding device which is assembled into a box-shaped frame using molded steel etc. downstream of the veneer lace veneer transport direction, and there are winding devices 1 before and after the winding device 1, respectively.
0 and a rewind device 20 are arranged. The framework of the winding and rewinding device 30 includes columns 11, 21, 21', etc. erected on the left and right sides of the front, rear, middle, etc., and a connecting beam 31 that connects the columns in the front and rear direction at the L portion, and Rail 3 installed near the middle height in the direction
2.33, and 34, and a stay (not shown) that connects the upper part between the pillars from side to side. Therefore, the middle part of the box-shaped frame is a space in which a rolled ball M, an empty reel R, etc., which will be described later, can be transported back and forth in the front and rear directions. In addition to the above-mentioned supports and rail groups, the construction framework is reinforced using auxiliary supports, gazette stays, etc., although not shown. The winding device 10 is mainly provided with a support 11 erected close to the veneer lace l side.
A variable speed electric motor (not shown) that drives the drive roll 12 fixedly installed below the veneer, a lifting mechanism (not shown) that raises and lowers the winding ball M or empty reel R along the support 11, and a veneer winding mechanism. The winding ball M is brought into pressure contact with the drive roll 12 by a pressing mechanism (not shown).

The reel R for winding the veneer has a veneer winding section made of a steel pipe or the like that is slightly longer than the width of the veneer to be cut, and a shaft end fixed to the left and right ends of the winding section, respectively. It consists of a rolling part constituted by a freely rotatable bearing etc. fitted to the one end, and the bearings of the rolling part are placed on rails 32, 33 and 34 installed on the left and right sides, which will be described later. The ball or reel is transported by rolling.

The veneer P cut out from the veneer race 1 passes through the delivery conveyor 7, and is synchronized with the veneer cutting speed (actually, the speed is increased by a few percent to account for slippage between the veneer and the veneer). .)
The leading edge of the veneer P is slightly wrapped around the outer circumferential surface of the empty reel R, which is transferred to the drive rule 12 by the driven conveyor 12' and lowered in the direction of the arrow along the column 11. The winding ball M is sequentially rotated in the direction of arrow 0 (counterclockwise direction) by a drive roll that is brought into pressure contact with the upper surface and driven in synchronization with the veneer cutting speed.
The veneer P is wound onto a reel R (sometimes a rolled ball M), and the diameter of the rolled ball gradually increases, and eventually the rolled ball that has been wound to a predetermined thickness is a -H veneer lace veneer cutting. The ball is suspended, raised along the pillar 11, and transferred, for example, in the direction of the arrow, to the rail 3z or 33, which serves as a storage stand for the one-roll ball V.

The rails 32 and 33 are connected from the winding device 10 side.
The structure is constructed with a downward slope toward the unwinding device 1j20, and therefore the rolled ball slowly moves along the rail in the direction of arrows 7 and 11 until it reaches an appropriately placed stopper (not shown). Move and stop.

The unwinding device 20 is normally configured to be able to unwind the veneer from the rolled ball at multiple locations.
Rewinding is possible at 1 and 21'.

The rewinding device 20 is a fixing device that fixes the end of the reel shaft of the rolled ball M (not shown).
The winding ball drive device 22 and 22' is composed of a plurality of belts, etc. that drive and rotate in contact with the outer peripheral surface of the single plate of the winding ball (not shown). are normally provided on the struts 21 and 21', respectively.

The rolled balls M stored on the rail 32 are sequentially transferred one by one to the position of the pillar 21, and are drawn to a rewinding position installed near the bottom of the pillar, where they are brought to the outer peripheral surface of the bearing at the end of the shaft of the reel R. is fixed by a fixing device (not shown). 2
2 is a winding ball drive device that contacts the outer circumferential surface of the winding ball M5 and rotates the winding ball in the direction of arrow G (clockwise direction). A raft lug belt or the like with fine irregularities on the outer peripheral surface is connected between multiple pulleys. It can be driven and stopped simultaneously by a drive device such as a brake motor (not shown).
The winding ball M5 can freely rotate via the bearing of the fixed reel R, and the winding ball receives a rotational force from its outer peripheral surface due to the contact drive of the winding ball drive device 22, and the winding ball is not wound more than necessary. This is to control runaway return. Due to the rotation of the rolled ball in the direction of arrow G, the veneer P advances in the direction of arrow H, for example, on the lower conveyor 40L of the drying device 40 which is connected to the bottom.
Send the veneer to. Further, in the support column 21', the veneer is sent to the upper stage conveyor 40U of the drying device in the force direction indicated by the arrow H' by the same means. Next, when all the veneers wound on the reel R are rewound to become an empty reel, the winding ball drive device 22 is flipped up by a swinging mechanism (not shown), and the empty reel R is raised and lowered along the support 21. The rail 34 is raised by a device (not shown) and transferred in the direction of the arrow 1 or ''. The veneer moves in the direction of arrow J and stops at appropriately placed stoppers (not shown) in preparation for winding up the next veneer. The above is an overview of the conventional device.

Next, the thin, wide, and irregularly-shaped raw wood that has been grown naturally is rotated by the spindle of the veneer lace, and then cut into veneers one by one by a cutter. is cut. Therefore, at the beginning of cutting, randomly shaped and irregularly shaped veneers are produced intermittently according to the irregular irregularities of the raw wood, and as the cutting progresses, it gradually becomes a continuous band-like veneer with a width commensurate with the length of the raw wood. When it develops into a board and the cross section of the log approaches a perfect circle, it becomes completely connected with a predetermined width (
Corresponds to the length of the log. ) veneers are produced with Ritsuzuki.
As the band-shaped continuous veneer continues, the diameter of the log becomes smaller, and eventually the core of the log, which is generally fragile, is produced continuously in a predetermined width. The veneer, which has a tendency to fall apart, is cut, and the process of cutting a single log is completed. The above cutting process is divided into stages: rough peeling for irregularly shaped intermittent veneer cutting, main peeling for continuous veneer cutting, and when cracks, cuts, etc. become noticeable, it is called core peeling, and the best quality veneer is obtained. When stripping the lumber, the cutting rate is reduced to about 0.5 mm to obtain a large area of the board, and it is used for the front and back veneers that appear on the surface of plywood products, and is used for rough stripping and core peeling. In contrast, when peeling, it is 1.2~
It is common practice to peel the core veneer to a thickness of about 3.0111 nm to obtain a core veneer that can be used in plywood products.

On the other hand, the veneer used in the veneer winding and unwinding device explained using Figure 1 is peeled veneer that is continuously produced in a band shape from veneer lace. The board could be wrapped around the ball, unwound, and unwound very smoothly.

By the way, raw wood accounts for more than 70% of the cost of plywood products, and Japanese plywood factories, which have to rely on raw material imports due to strict export regulations and other raw wood conditions, rely on inexpensive low-grade raw wood. As a result, the problem was how to obtain as many front and back veneers as possible from low-quality, inferior raw materials.

) Although veneer cutting for veneer lace has become possible, new problems have arisen in the processing of the veneer after cutting, and in the veneer winding and unwinding equipment.

The rough-peeled veneer in the early stage of cutting the raw wood, which produces irregularly shaped veneers, and the core-peeled veneer in the latter half of the cutting process where cracks, chips, etc. have started to appear, are wound up by the cutting device 10, and the winding is abandoned. However, due to the above reasons, we were forced to expand the range of thin veneers and agricultural veneers from inferior logs, and as a result, we were able to produce core-stripped veneers that met the specified width despite defects such as cracks and cuts. It was decided that the board would be cut into many thin pieces and rolled up as front and back plates.

Although the issue of winding the veneer has been largely solved by the development of the i11# system which is almost completely synchronized with the cutting speed of the veneer lace in the device 10, a major bottleneck has appeared in the unwinding device 2o. In other words, as shown in Figure 1, the veneer is released from near the upper end of the outer circumferential surface of the rolled ball M5, so no matter how much you synchronize the unwinding speed with the feed speed of the lower conveyor 4OL of the drying device 4o, it will break and break. If the veneer is a little loose and tries to fall downward from the top edge, it will crack, which will encourage cuts and the like, causing the crack to expand and disturb the way it is being transported, or because it is a thin veneer, the crack will eventually extend over the entire width. The veneer may be damaged or completely separated and its edges may curl up.
Various problems such as being transported in a meandering manner occurred one after another, leading to extremely irregular heartbeats.

The present application completely eliminates the above-mentioned obstacles, and embodiments will be explained using figures. ; Figure f72 is a side sectional view of the veneer rewinding device 20' of Embodiment 7 of the present invention, and elements with the same symbols and advancing direction symbols as in Figure 1 have the same configuration,
It represents the action, effect, direction of travel, etc. In the figure, the rolled ball M5, like the spear 11J, is appropriately driven in the direction of arrow Q (clockwise direction) by the rolled ball driving device 22. spear 1
The difference from the figure is that a guide conveyor constituted by a plurality of belts and the like that are driven in contact with or very close to the outer peripheral surface of the rolled ball and a veneer reversing device rIt50 have been added.

51 is a guide conveyor that contacts the outer peripheral surface of the unwinding single plate of the rolled ball M5 along the abbreviated circumference (about y44 part) of the outer circumference vIJ (the right outer peripheral surface of the rolled ball M5 in Figure 2). Consisting of a plurality of belts/2 wound between a plurality of guide pulleys 52 (some of the pulleys may be driven) that are arranged close to each other and driven in the veneer transport direction in the direction of arrow G, The device is capable of approaching or separating from the winding surface as the diameter of the winding ball decreases as the veneer unwinds. Reference numeral 53 denotes a reverse conveyor, in which Il number of belts are wound while maintaining a substantially horizontal state between a relatively large-diameter pulley 54 and a small-diameter boob 953P, and are arranged in contact with or close to the lower outer peripheral surface of the wound ball M5. The veneer rolled from the rolled ball and guided in the F direction by the guide conveyor 51 is transferred to a drying device 40, for example, in the direction of a dryer (arrow H).
direction. ), and also makes a 360° U-turn downward in the direction of arrow G2 along a reversing pulley 54 having a relatively large diameter.

Reference numeral 56 denotes a guide conveyor for the spear 2, which runs a number of belts along the approximate circumference of the outer peripheral surface of the reversing pulley 54 (the left outer peripheral surface of the pulley 54 in Figure 2), and also conveys the four guide pulleys 5.
6, and pulley 54 to rotate the veneer in the 02 direction.
This prevents the veneer from falling off the outer peripheral surface of the veneer. That is, when passing through the booze 954, the veneer is held between the conveyor 53 and the guide conveyor 56, which are driven along the outer peripheral surface of the pulley, and makes a U-turn. 58 is a reverse pulley 54
For example, this is a transfer conveyor installed at a slightly upward slope and stretched between the lower conveyors 4OL of the drying device 40, which start near the lower outer peripheral surface of the drying device 40 and are connected downstream of the device. The reversing device 1i 150 consisting of the guide conveyor 51, reverse conveyor 53, spear 2 guide conveyor 56, and transfer conveyor 58 is normally connected to the lower conveyor 40 of the drying device 140.
Drive as appropriate in synchronization with the feed speed of other devices installed on the downstream side of veneer conveyance, such as being driven in synchronization with the conveyance speed of L.
! 11111 (not shown). In addition, the half of the reversing device formed by the combination of the conveyors 53, 56 and 58 contacts or approaches the lower part of the winding surface as the winding ball diameter gradually decreases as the winding ball M5 is unwinded. Alternatively, it is constructed as an elevator door I function by a lift mechanism (not shown) that can be separated. Further, the lower half of the reversing device i50 is semi-fixed by omitting the lifting mechanism,
It also works as a mechanism to lower the rolled balls one after another. Alternatively, the winding ball driving device @iz2 may be omitted and the guide conveyor 51 or the conveyor of the reversing device 50 may be brought into pressure contact with the outer circumferential surface of the winding ball to also serve as the winding ball drive.

Reference numeral 59 denotes a tipple conveyor, which bridges the small diameter pulley 53F at the tip of the reverse conveyor 53 and the lower stage conveyor of the drying device 40 as shown in the imaginary line in Figure 2 when performing conventional rewinding. The guide conveyor 51 is appropriately retracted to rewind the veneer, so its installation is optional if necessary. The work order shown in Figure 1 applies mutatis mutandis to the transfer of rolled balls or the lifting and transfer of empty reels.

According to the device shown in Figure 2, even cracked or torn veneers are smoothly rewound by the guide conveyor 51 that guides the veneer along the winding circumferential surface, and then the reversing pulley 54 makes a U-turn without delay and transports the veneer. It was placed on the conveyor 58 and cracked.
Even veneers with defects such as cuts are sent as they are to a drying device 40 or the like, where damage to the veneers and other obstacles are removed.

Although the explanation is omitted, the same rewinding device as the device in the above-mentioned 21 is also arranged in the pillar 21' of Figure 2. In the embodiment shown in FIG. 2, the veneer winding direction of the winding device 10 is counterclockwise (in the direction of arrow C), whereas the veneer winding direction of the winding ball M5 in the unwinding device 20 is The return rotation direction is the clockwise rotation direction (in the direction of arrow G) opposite to the winding, and a guide conveyor 51 is provided approximately on the right half of the winding rising circumferential surface to pull out the veneer from the lower end of the winding bobbin. The veneer is fed backwards in the opposite direction to the direction in which the entire veneer travels (in the direction of arrow H), and then the veneer is made a U-turn by the veneer reversing device 50 and fed forward (arrow H
direction. ).

As an application example of Fig. '472, the winding ball is rotated in the same clockwise direction as in Fig. 2 (in the direction of arrow G), and the ball is wound around the guide conveyor 51 approximately to the left of the rising circumferential surface (l/4 half circumference is also acceptable). The starting end of the transfer conveyor, which pulls out the veneer from the top end of the rolled ball, places the veneer on it, and transfers it approximately horizontally (inclined transfer is also acceptable), is placed close to the point where the veneer is pulled out of the sounding ball. In this case, the rolled ball driving device 22 contacts the lower outer peripheral surface of the rolled ball M5 and drives it in the direction of arrow G, and the veneer reversing device 50 is omitted or a guide conveyor is used. 51 may be wound and driven in pressure contact with the rising circumferential surface, and the winding ball driving device 22 may be omitted.

Figure 3 shows a veneer winding and unwinding device 113 of another embodiment.
This is a side sectional view of 0′, and the difference from FIG. The time is reversed, and the single plate guide conveyor 51
This is the point where L is placed. Each element with the same symbol as the spear 1 figure,
The traveling direction code etc. have the same configuration and function.

In Figure 3, reference numeral 60 is a winding forward/reversal device that can insert the left and right sides of the rolled ball M1, and a support 15 is erected between it and the support 11 to maintain a space that allows the rolled ball M1 to be reversed left and right, as shown by the imaginary line. A fulcrum bracket 61 is installed above the middle part in the front-rear direction and left-right direction between the pillars, and from the bracket, a cable 62 such as a wire rope can be raised and lowered as appropriate, and the left and right shaft ends of the rolled ball V are suspended at the same time. It is suspended by connecting possible hanging fittings 63. The fulcrum bracket 61 is
For example, a running trolley (not shown) placed on a rail or the like installed between the left and right connecting beams 31 is used to move the rolled ball M or the empty reel R to either the left or right end except when the rolled ball is being reversed. Care has been taken to ensure that it does not interfere with directional movement. Note that the rope may be omitted and only the hanging fitting is used, and the winding ball stopper, which is not shown and is on the back side of the winding ball Ql in the figure, is located in the approximately middle dark area between the supports 12 and 15 of the rail 32, 33. The stopper is provided on the rail and can be retracted from the rail. The above winding forward/reverse device 6
In the actual situation at o, the rolled ball after winding of the veneer is placed on the rail 32 and moves from left to right in the figure according to the inclination of the rail. In this case, the rolled ball stopper installed on the rail has advanced onto the rail, so the rolled ball temporarily stops approximately halfway between the pillars 11 and 15. Next, the hanging metal fitting 63f that had been moved far to either the left or right. : Pull it out to the approximate center in the left-right direction and lower it, and attach the metal fitting 63 to the left-right shaft end of the winding ball M1.
The end of the ball is hooked to raise the after-drilling tool, the rise is stopped at an appropriate height, and the left and right sides of the rolled ball are reversed in the direction of the arrow Y and replaced. Continue to lower the hanging bracket 63 and attach it to the rail 3.
After the rolled ball M1 is placed on the rail 32, the metal fitting is retracted to either the left or right and the rolled ball stopper on the rail is moved back, and the rolled ball is transferred on the rail 32 in the direction of the arrow p1 with the left and right swapped. It waits at a predetermined position.

Next, the rewinding device 120'' will be explained.

The rewinding devices are installed on the pillars 21 and 21', respectively, as in Figure 1. 22L is a winding ball drive device, which has the same configuration as in Figure 1, but is in contact with the winding rising circumferential surface and rotates in the counterclockwise direction opposite to that in Figure 1, that is, the same direction as arrow C of the veneer winding rotation. The winding ball M5' is rotated in the direction of the arrow mark.

A number of guide pulleys 52'1 are disposed in contact with or close to the outer circumferential surface along approximately half the circumference (or about 4 half circumferences) of the side outer circumferential surface) and are driven in the veneer transfer direction in the direction of the arrow.
It consists of a belt of A principle wound between l (one part of the bobbles may be driven), and as the diameter of the wound ball decreases due to unwinding of the veneer, it approaches the rising circumferential surface of the winding or 1131
It is made up of 4 parts.

58L is a lower conveyor 40L of the drying device 40, which is connected to the four sections of the guide conveyor 51L and one hand of the device.
It is a transfer conveyor that is stretched almost horizontally on the lij, and is configured to be able to move up and down using the starting end of the lower stage conveyor 40L as a fulcrum, and maintains a constant interval close to the winding and rising circumferential surface by following the gradual decrease in the diameter of the winding ball. It is a device to do this. Alternatively, the conveyor may be fixed so that the rolled balls are gradually lowered. Further, the guide conveyor 51L and the transfer conveyor 58L are normally connected to the lower conveyor 40 of drying bags W140.
It is driven by drive machine # (not shown) as appropriate in synchronization with the feed speed of other devices installed on the downstream side of veneer conveyance, such as being driven in synchronization with the conveyance speed of L.

In addition, a rewinding device similar to that described for the support pillar 21 is also installed on the pillar 21''F side, for example, a poor drying device lol!
40 is connected to the upper stage conveyor 40H.

In the embodiment with the configuration shown in Figure 3, the inverted rolled ball VTTX11, which is suspended on the rail 32-L, is called into the rewinding device 20' and the rewinding bell (22L) rotates the rolled ball in the direction of the arrow mark. As a result, the veneer is unwound from the vicinity of the lower side of the winding ball, and the guide conveyor 51L
The veneer is smoothly released along the winding and rising circumferential surface, and then the veneer is sent approximately horizontally to the drying device 40 by the transfer conveyor 58L without any damage. In this example, a winding ball reversing device is installed to change the left and right sides of the winding ball between the winding of the veneer in the winding device 10 and the unwinding of the veneer in the unwinding device of 20". The rewinding rotation direction (arrow 0 direction) and the rewinding rotation direction (arrow 0 direction) are the same (counterclockwise rotation in each figure), so that the rewinding device 20' rotates approximately the left half of the outer peripheral surface of the wound ball M5'. A guide conveyor 51L is installed in the spool, and a transfer conveyor 58L near the spool section draws out the veneer from the lower end of the spool and immediately transports it in the direction of arrow H.

Note that the rolled ball reversing device 60 is configured by suspending a hanging fitting from above.
In this device, a rolled ball is suspended and the left and right sides of the rolled ball are changed by a person, but the rolled ball is supported from below using a liftable cart or the like that supports the left and right ends of the rolled ball from below.1. (However, it is also possible to use a turntable or a device that switches the left and right sides of each cart using a cart that can rotate left and right.Also, as in the case of Figure 2, the guide conveyor 51'L is brought into pressure contact with the rolled ball. In some cases, the winding ball driving device 22L may be omitted.

According to the present invention as explained above, there is no damage to the veneer or any other problems when unwinding the veneer, and veneers produced by cutting the core, which was conventionally considered core veneer, can now be used as front and back veneers. It is.
