Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, a veneer veneer obtained by cutting a log with a veneer lace is wound with a yarn by a winding device to form a wound ball (hereinafter simply referred to as a reel). ).
[0002]
[Prior art]
A veneer veneer obtained by cutting a log with a veneer lace is once wound around a reel by a winding device to form a wound ball, and then the wound ball is rewound by a rewinding device and rewound. The plate is fed into a drying device and dried.
Then, the reel after the veneer single plate is rewound is fed back to the veneer race side and is repeatedly used in the winding and rewinding process of the veneer single plate again.
As shown in FIG. 12, the reel has a shaft 3.3 protruding at both ends of a take-up shaft 1 having a horizontally long drum shape, and rolling wheels 4.4 are attached to the shaft 3.3. When winding the veneer veneer around a wound ball, as shown in FIG. 13, the idler wheel 4 is received by a V-shaped support 14 and the take-up shaft 1 is touch roll or a conveyor belt (not shown). ) Is supported in a freely rotating manner and is sent back to the veneer race side, the rolling wheels 4 are placed on the inclined rail 9 and sequentially sent out from the high position to the low position along the inclination.
A large number of reels are inserted in the path for performing the series of steps. Therefore, in the section of the inclined rail, a plurality of reels wait in a dumpling state while waiting for their turn.
[0003]
By the way, when winding a veneer veneer, a winding device for winding a yarn or a tape together with the veneer veneer is widely used for guiding and holding the veneer veneer. As shown in FIGS. 14 (a) to 14 (e), a thread locking surface is provided by adhering a large number of particles continuously to the surface in the rotational direction or by adhering in a strip shape with the abrasive surface of sandpaper as the outside. Then, the tip of the yarn 15 is discharged by compressed air or the like so as to get over the yarn locking surface 2 of the reel R to be rotated, and the yarn 15 is entangled with particles or abrasive grains to automatically wind the yarn 15 around the reel R. The one in which the veneer veneer 16 is wound together with the yarn 15 is highly evaluated.
The thread locking surface is appropriately selected from those in which the thread is easily entangled, such as a glued metal filament such as a metal scrubber, affixing a surface fastener, or a knurled surface of the winding shaft, As the yarn to be wound together with the veneer veneer, for example, a polyester yarn having a thickness of about 500 to 1000 denier can be preferably used. However, the yarn is easily entangled with the thread locking surface and can withstand the tension during winding. Any thread can be used as long as it is thick.
[0004]
[Problems to be Solved by the Invention]
However, in the process in which the veneer veneer is wound up and then the reel RR after rewinding as described above is guided by the inclined rail 9.9 and fed back to the veneer race side, Since RRs touch each other and the subsequent reel R collides with the waiting reel R, contact with each other is unavoidable, and the rolling shaft 4 is attached to the shaft 3 via a bearing. Although it has been considered that the winding shaft 1 does not rotate even when the rolling wheel 4 rotates, depending on the biased state of the center of gravity, the rolling shaft 1 may rotate slowly although it moves.
In the conventional reels, as shown in FIG. 13, when the reels RR touch each other, the take-up shaft 1 and the take-up shaft 1 come into contact with each other. Even if the take-up shaft 1 does not rotate, If the thread locking surfaces 2.2 formed on the peripheral surface of the winding shaft 1 come into contact with each other and the main part where the thread is easily entangled is crushed, and rotation is accompanied by this, the abrasive grains are fixed. On the thread locking surface formed by pasting sandpaper, particles and abrasive grains rub against each other, and the particles and abrasive grains peel off.
As a result, the thread cannot be entangled in the end, and it is necessary to newly add or fix abrasive grains, or to replace with new sandpaper. This reduces workability and makes maintenance management complicated. Met.
As shown in Japanese Utility Model Publication No. 63-664, even when a reel that prevents meandering and rotation of the winding shaft is used, the reel rotates slightly, but the same problem occurs. Remains.
[0005]

DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of a reel according to the present invention will be described with reference to the drawings.
FIG. 1 shows the first embodiment, and FIG. 2 is a partial cross-sectional explanatory view of the direction of the arrow as seen from the AA chain line in FIG.
That is, the reel R1 is formed with a plurality of thread locking surfaces 2.2... On the circumferential surface of the take-up shaft 1 having a horizontally long drum shape, and shafts 3.3 project from both ends thereof. A rolling wheel 4.4 is attached to the tip of the shaft 3.3.
A ring member 5.5 as a stopper member is fixed to both sides of the winding shaft 1 so as to be in close contact with the side surface of the winding shaft 1 so as to be integrated.
As shown in FIG. 2, the ring member 5.5 has a diameter close to the outer periphery of the shaft 3, and the outer diameter is larger than the diameter of the winding shaft 1. It is composed of two plates 5a and 5b obtained by dividing a perforated disk larger than the outer periphery of the thread locking surface 2 formed by being bonded so that the bonding surface is on the outside.
When these two plate members 5a and 5b are combined, a hole 6.6 extending from the peripheral surface of one member 5a to the other member 5b is formed as shown by a broken line, and the hole of the member 5b is formed. 6 is provided with a female screw 7.
In addition, in the vicinity of the peripheral surface of the hole 5a formed in the plate member 5a, a large-diameter hole portion 6a having a diameter larger than that of the hole 6 is formed so that a head of a hexagon socket head bolt 8 described later can be inward. It has become.
[0008]
The two plate members 5a and 5b are fitted on the take-up shaft 1 with the shaft 3 interposed between them so as to be in close contact with the take-up shaft 1, and reach the male screw 7 of the hole 6 from each large-diameter hole 6a. Hexagon socket head cap screw 8 is inserted and screwed in and fixed.
In FIG. 2, a circle indicated by a two-dot chain line is an abrasive grain adhesion surface of the sandpaper affixed to the peripheral surface of the winding shaft 1, that is, a thread locking surface 2. In the reel R1 configured as described above, the reel R1. When the R1s collide or come into contact with each other, as shown in FIG. 3, only the ring members 5.5 are brought into contact with each other, and the winding shaft 1 having a diameter smaller than that of the ring member 5 is of course formed on the winding shaft 1. The thread-engagement surfaces 2.2, that is, the abrasive-bonding surfaces of the sand paper constituting the yarn-engagement surface 2.2 do not come into contact with each other.
As a result, sandpaper abrasive grains are prevented from peeling off during movement, and the frequency of exchanging sandpaper is reduced, so that workability is improved and maintenance management is facilitated.
[0009]
In the first embodiment, the ring member is fitted to the end surface of the take-up shaft so as to sandwich the shaft, but is thicker than sandpaper along the end edge of the take-up shaft. It can also be configured by fitting a ring member.
In the structure adopted in this embodiment, since the ring member has a two-part structure, it can be easily retrofitted to an existing reel.
In the first embodiment, the ring member is used as the stopper member, but a rolling wheel can be used as the stopper.
Next, a second embodiment using the rolling wheel as a stopper will be described.
[0010]
In the second embodiment shown in FIG. 4, the rolling wheel 4.4 of the reel R <b> 2 is formed to have a diameter larger than the outer periphery of the thread locking surface 2.2, and moves while being guided by the rail 9. In between the reels R2. When R2 collides or comes into contact with each other, as shown in FIG. 5, only the rolling wheels 4.4 come into contact with each other, so that the winding shaft 1 having a diameter smaller than that of the rolling wheels 4 is formed on the winding shaft 1. The thread-engagement surfaces 2.2, that is, the abrasive-bonding surfaces of the sand paper constituting the yarn-engagement surface 2.2 do not come into contact with each other.
In this embodiment, since the rolling wheel is used as a stopper, a new member is not necessary as a stopper for regulating the interval, and it is sufficient to increase the diameter of the rolling wheel.
By the way, the stopper member can be provided integrally with the winding shaft, or can be provided on the shaft other than using a rolling wheel.
[0011]
Next, the embodiment will be described with modification examples.
FIG. 6 shows a third embodiment. The sum of the radius of the shaft 3 is wound on the shaft 3 on one side of the reel R3 at a position between the winding shaft 1 and the rolling wheel 4. A flange 10 having a radius larger than the diameter of the thread locking surface formed on the shaft is attached.
In addition, the diameter of the axis | shaft said here points out the part in which the flange was formed, and it is a premise that an axis | shaft is a symmetrical shape to the last.
The reels formed in this way are arranged so that the left and right of each reel are interchanged with respect to the row direction, and as shown in FIG. 7, while being guided and moved by the rail 9.9, the reel R3. When the three members collide or come into contact with each other, the flange 10 and the shaft 3 only come into contact with each other, and the thread locking surface 2.2 formed on the winding shaft 1 as well as the winding shaft 1, that is, thread locking. There is no contact between the abrasive-bonding surfaces of the sand paper constituting the surface 2.2.
In this embodiment, since the flange is provided only on one of the shafts, the labor for providing the flange can be halved.However, if the flanges do not cushion each other, they are provided on both shafts to balance the left and right. Can be taken.
[0012]
In any of the first to third embodiments described above, since the outer periphery of the stopper member is circular, the impact when it collides is relatively small, but it may be polygonal.
An embodiment in which the stopper member is a polygon will be described next.
In the fourth embodiment shown in FIG. 8, the outer periphery of the ring member in the first embodiment is changed to a square shape, and the hexagon socket head bolt 8 is used to attach the shaft 3 to the shaft 3 as in the first embodiment. It is fixed.
The stopper member 5 'has a distance from the shaft center of the shaft protruding from both ends of the winding shaft to the nearest side larger than the radius of the portion where the thread locking surface of the winding shaft is provided. Even if they contact each other, the thread locking surfaces 2.2 formed on the winding shaft do not contact each other.
The outer periphery of the stopper member is not limited to a square, and the same effect can be expected whether it is a hexagon or an octagon.
The idea of using a stopper member having a polygonal outer periphery can be applied to the second or third embodiment, and a polygonal flange can be adopted in any of the embodiments.
By making the stopper member polygonal, when placed on the floor or the like, one side of the stopper member is in contact with the floor, so that the reel itself can be prevented from rolling.
[0013]
Many embodiments that can be suitably used in addition to these embodiments are conceivable. Finally, these will be described together.
FIG. 9 shows a fifth embodiment. A flange 11 is attached to a shaft 3.3 on both sides of the reel R5 at a predetermined position between the winding shaft 1 and the rolling wheel 4. ing.
When the reels formed in this way are aligned in a row with the ends of the shaft protruding at both ends of the take-up shaft aligned and in close contact with each other, as shown in FIG. Since the flanges 11.11 are in contact with each other on the same line, the sum of the radius of one flange 11 and the radius of the other flange 11 is equal to the radius of the portion where the one thread locking surface 2 is provided and the other. If it is larger than the sum of the radii of the portion where the thread locking surface 2 is provided, the thread locking surface 2.2 provided on the winding shaft 1, that is, the sand paper constituting the yarn locking surface 2.2 The contact surfaces of the abrasive grains are not in contact with each other.
Therefore, as shown in FIG. 11 showing the sixth embodiment, it can be expected that the same effect can be obtained by alternately arranging combinations of flanges 12.13 having different diameters.
In this way, even if the number is insufficient, the same object can be achieved by a combination of reels having different flange diameters.
[0014]
In the present invention, the attachment structure of the ring member and the flange can be appropriately changed by using a known technique such as press-fitting and welding. For the purpose of the present invention, the ring member and the flange are wound from the beginning. The take-up shaft and the one formed integrally with the shaft are also included.
Also, when changing the diameter of the rolling wheel, not only can the rolling wheel be replaced with one having a larger diameter, but the diameter can be increased by fitting a ring around the existing rolling wheel.
[0015]
【The invention's effect】
According to the present invention, in a reel for winding a single plate together with a yarn, when continuously conveyed, the yarn locking surfaces provided on the peripheral surface of the reel do not come into contact with each other even if the reels hit each other.
Therefore, in the case where the thread locking surface is formed by adhering abrasive grains or pasting sandpaper, the thread locking surface such as abrasive grains is not damaged, and the thread locking portion is replaced. The frequency is reduced, the workability is improved, and maintenance management is facilitated. Even when the thread locking surface is formed by other means, the locking function can be kept long.
[0016]
The invention of claim 2.4.5 is economical because it is only retrofitted to an existing reel, and the invention of claim 3 only requires replacement of rolling wheels.
In the invention of claim 4, when placed on the floor or the like, one side of the stopper member comes into contact with the floor and the reel itself is prevented from rolling.
Furthermore, in the invention of claim 5 , even when the number is insufficient, it is possible to cope with a combination of reels having different flange diameters.
