Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention is based on a method in which a veneer veneer cut by a veneer lace is once wound onto a take-up reel to form a wound ball, and this wound ball is placed at a rewinding location. The present invention relates to a method and device for locking a rolled ball to prevent the rolled ball from being rewound when being transported.

"Prior Art" As shown in FIG. 10, a veneer veneer 1 cut with a veneer lace is conveyed on an incoming conveyor 2, and a side drive roll 4 is installed at an appropriate distance from a pulley 3 at the end of the conveyor 2. The rolled ball 6 is wound by the winding reel 5 which rotates in pressure contact with the rolled ball 6, and after winding is completed, the rolled ball 6 rises within the reel support 8 via the lifting device 7 and is transferred to the transfer rail 10 of the rolled ball stocker 9. Ru. Next, the next winding rail 5 is lowered from the return rail 12 of the reel stocker 11 to above the side drag roll 4, and new winding is started.

Normally, this transfer rail 10 has a slight downward slope toward the unwinding place located at the front, and the rolled balls 6 are temporarily stored in the rolled ball stocking area 9 or as they are at both ends of the winding reel 5. As the trochanter rolls, it is transferred forward while rotating.

Therefore, the veneer veneer 1 that has been wound onto the take-up reel 5 and turned into a bobbin 6 is also rewound from its terminal end on the way to the unwinding location, resulting in failure to achieve the intended purpose. Become.

Conventionally, in order to prevent the above-mentioned unwinding phenomenon, the roughly central part of the rolled ball 6 wound on the take-up reel 5 is tied with a rope, or the end of the continuous veneer veneer 1 is tied with tape or staples. The parts were fixed at multiple locations.

Furthermore, in recent years, as disclosed in Japanese Unexamined Patent Publication No. 158202/1982, a technique has been developed in which the tip of the linear object is wound around the ball by air from a linear object discharge device, and the linear object is wound around the ball. As disclosed in Japanese Unexamined Patent Publication No. 59-127702, a technique has been proposed in which the wires are heat-fusible tapes and the tapes are heat-welded to each other.

``Problem to be Solved by the Invention'' However, the former of these conventional means are all done manually by workers, and the working environment is poor, so they are not only extremely inefficient, but also dangerous. It is accompanied by

Regarding the latter, a linear object discharge device,
In addition, both heat-adhesive tapes are not configured to be movable according to the diameter of the wound ball, making the operation of feeding them into the wound ball uncertain, and furthermore, the wire material after overlapping wrapping may be caught in the head. When cutting with tension due to the rotational force of a winding ball, welding heat-fusible tapes together, adhering linear objects together, welding heat-fusible tapes,
Questions remain about the fusing work.

``Means for Solving the Problems'' In view of the above, the present invention provides tapes that are placed oppositely while maintaining a constant distance from the increasing surface of the rolled veneer when winding a continuous veneer veneer. The heat-fusible tape fed out from the tape reel is passed through the guide body, and air is supplied to the tape just before the end of winding the winding ball, so that the tip is wound around the winding ball. The tape is wound around the ball several times, and then the heating element is advanced to the surface of the ball to press the tape wrapped around the outer circumference of the ball with a tape presser, and the tape on the outside and the tape located on the inside are pressed together. There is a method in which the rolled balls are secured by welding them using a heat source.

is connected to operate the second double link 79 to control each link motion.

"action" Next, the action will be explained.

First, the discontinuous veneer veneer 1 that is cut from the sapwood of the log and cannot be rolled up is temporarily discharged outside.

For this reason, the rod 16 of the compressed fluid cylinder 15
is extended, and the terminal end of the pedestal 13 is pushed down using the vicinity of the starting end pulley shaft 14 as a fulcrum, and the sliding frame 43 is moved obliquely downward along the sliding guide 44 while keeping the carry-in conveyor 2 in a nearly horizontal state. .

At the same time, the rod 35 of the pressurized fluid cylinder 34 is contracted, the pressurizing pulley 32 is rotated, the winding guide belt 37 is brought into a substantially horizontal state, and the rod 21 of the fluid cylinder 20 for elevating the discharge conveyor is
By extending the machine frame 22 and pushing down the machine frame 22, the carry-out conveyor 26 is lowered to be at the same height as the carry-in conveyor 2.

Moreover, the sliding frame 43 is moved along the sliding guide body 44,
By operating the slide frame lifting fluid cylinder 41, the slide frame is moved diagonally upward and the press roll 49 is retracted above the conveying surface.

Under this condition, the discontinuous and unrollable veneer veneer 1 is conveyed on the carry-in conveyor 2, passes below the pressure roll 49 and the take-up reel 5, and is transferred to the wind-up guide belt 37 and the carry-out conveyor 26. It is carried out of the aircraft by the

Next, when cutting the continuous veneer veneer 1 from the raw wood, each drive is temporarily stopped, and the pedestal 13, the winding guide belt 37, the carry-out conveyor 26, and the sliding frame 43 are returned to the winding state.

That is, the pedestal 13 is pivoted upward by the pressing fluid cylinder 15 with the starting end pulley shaft 14 as a fulcrum, and the upper peripheral surface of the side drive roll 4 is pressed against the lower peripheral surface of the take-up reel 5. , rod 42 of sliding frame lifting fluid cylinder 41
by reducing the pressure roll 49 to the take-up reel 5.
force to the side.

Further, the pressurizing pulley 32 is urged toward the outer circumferential side of the take-up reel 5 by the pressurizing fluid cylinder 34,
A take-up guide belt 37 is stretched along the lower side of the outer circumference of the take-up reel 5. Further, the discharge conveyor 26 is raised by the operation of the fluid cylinder 20 for raising and lowering the discharge conveyor, and the pressure roll 27 is disposed opposite to the side surface of the take-up reel 5 at an appropriate distance.

At this time, the pressurizing body 62 is urged toward the side surface of the take-up reel 5 by the pressurizing body pressing fluid cylinder 58,
The take-up guide member 64 is stretched along the upper surface of the outer periphery of the take-up reel 5.

Next, the cutting speed and the conveying speed are synchronized, and the continuous veneer veneer 1 is supplied to the take-up reel 5 by the carry-in conveyor 2, and the tip portion is passed to the take-up guide belt 37 and the take-up guide member 64. It is wound along the outer peripheral surface of the take-up reel 5. During winding, the rolling down force accompanying the increase in the diameter of the winding ball 6 overcomes the pressurizing force of the pressing fluid cylinder 15, and the pedestal 13 is sequentially swung downward by the increase in the diameter of the winding ball 6.

With this increase in the diameter of the winding reel 6, the pressure pulley 3, which was initially urging the vicinity of the center of the side surface of the winding reel 5,
2 is pushed by the winding ball 6 and swings forward, and furthermore,
As the gantry 13 swings downward, the winding range of the winding guide belt 37 surrounding the winding ball 6 also sequentially moves downward.

On the other hand, the pressure roll 27, which was placed opposite to the vicinity of the center of the side surface of the take-up reel 5 at an appropriate distance,
When the rolled ball 6 reaches an appropriate diameter, for example, 190 mm to 200 mm, it is pushed by the rolled ball 6, and then sequentially swung forward.

When the pedestal 13 swings downward and the pressure roll 27 swings forward, the pressure roll 27 and the veneer veneer introduction member 29 are expanded, but the lower part of the outer peripheral side of the winding ball 6 is connected to the lower winding drum. It is then surrounded by a veneer veneer introduction member 29 which is sequentially unwound from 28.

In this case, the guide body 30 is arranged so that the amount of change in the biasing position of the pressure roll 27 with respect to the rolled ball 6 is minimized, and the surrounding range of the rolled ball 6 of the veneer veneer introduction member 29 is sequentially expanded downward. Since the position of the lower winding drum 28 is set, the veneer veneer 1 is moved to the center of the unloading side of the veneer veneer 1 of the winding ball 6 due to the cooperation between the winding guide belt 37 and the veneer veneer introducing member 29. It will be introduced in the near future.

Furthermore, initially, the veneer veneer 1 of the take-up reel 5
The pressure roll 49, which had been urging the vicinity of the center of the side surface on the carry-in side, was moved downward along the sliding guide 44, and the pressure roll 49, which had been urging the vicinity of the center of the side surface of the veneer veneer 1 on the carry-out side, was moved downward along the sliding guide 44. The body 62 is pushed by the winding ball 6 and is swung forward.

As the pressure roll 49 is moved diagonally downward and the pressure body 62 is swung forward, the winding guide member 64 moves along the outer periphery of the rolled ball to the upper winding drum 6.
It is rewound sequentially from 3. In this case, the amount of change in the biasing position relative to the pressurizing body 62 is minimized, and the pressure roll 49 is set to move obliquely downward as the pedestal 13 swings while biasing the winding ball 6. Therefore, the winding guide member 64 moves from near the center of the side surface of the unloading side of the veneer 1 of the winding ball 6 through the upper surface of the outer periphery.
The area up to the inlet of the veneer veneer 1 must be surrounded at all times.

Therefore, the rolled ball 6 wound on the take-up reel 5 is
The veneer veneer 1 that has been conveyed on the carry-in conveyor 2 from the minimum diameter to the arbitrary diameter is moved by the cooperation between the winding guide belt 37 and the veneer veneer introducing member 29, as well as by the winding guide member 64. , and will be sequentially wound up following its outer circumference.

Then, just before the end of winding the winding ball 6, the absence of the veneer veneer 1 on the carrying-in conveyor 2 is confirmed, or the end of the continuous veneer veneer 1 is detected by a command from the veneer race, At this time, from the standby state shown in FIG. 5, the prime mover 86 is first activated to move the increased number of rolled balls 6 to the sliding frame 43, which is disposed oppositely with a constant interval. 74 to swing the support plate 75 forward.

Next, air is supplied from the attachment port 76 to the guide groove 77 of the tape guide body 78 for a certain period of time, and the tip of the tape 66 is fed forward by the jetting force of the air, as shown in FIG. The terminal end of the veneer veneer 1 is rolled onto a winding ball 6 on a side drab roll 4.

After a certain period of time has elapsed, the supply of air is stopped and the pressure regulating fluid cylinder 68 is operated to press the cam floor 70 against the tape reel 67 surface and release the tape 6.
If the tape 66 is braked from being fed out, the tape 66 will be wound around the outer circumferential surface of the rolled ball 6 while maintaining a tensioned state.

The length of the tape 66 wound around the diameter of the rolled ball 6 is such that it makes at least one rotation around the outer circumference of the rolled ball 6 and exceeds it by a slight amount, and this length can be determined by measuring the diameter of the rolled ball 6, for example. The calculated outer circumference is determined based on the relationship with the diameter and circumferential speed of the side drag roll 4, or is determined by detecting the amount of rotation of the shaft of the take-up reel 5. After the roll 66 is wound, the side drab roll 4 is stopped.

When the winding ball 6 is stopped, the tape 66 is under tension in the tangential direction between the outer periphery of the winding ball 6 and the tip of the tape guide 78. Under this state, the heating body fluid cylinder 89 Rod 90
When extended, the second double link 79 swings and moves the heating body 81 forward.

By moving the heating body 81, as shown in FIG.
First, the tape presser 84 presses the tensioned tape 66 wound around the outer periphery of the rolled ball 6.
At the same time as the tape 66 is traced around the outer periphery of the tape 66, the heating wire 85 melts and cuts the tape held under tension by the tape presser 84 and the tape guide 78.

During this time, the heating element 81 is getting closer to the surface of the rolled ball 6, and the heating source 83 is coming from the perforation of the tape presser 84.
contacts the tape 66 for a certain period of time, welds the outer tape 66 and the inner tape 66 and locks the wound ball 6.

After the winding ball 6 is locked, the heating body fluid cylinder 89 and the prime mover 86 are operated in reverse to return the heating body 81 and the tape guide body 78 to their original positions. Furthermore, the rod 59 of the fluid cylinder 58 for pressing the heating element
is reduced, the linking arm 61 is rotated clockwise in FIG. 2, and the fluid cylinder 53 for rotating the swing frame is
The winding guide member 64 is opened from the top surface of the winding ball 6 by reducing the rod 54 and rotating the swinging frame 52 clockwise about the sprocket shaft 50 as a fulcrum.

Thereafter, the rolled ball 6 held by the tape 66
is lifted up and down by a lifting hook (not shown) inside the reel support 8 via the lifting device 7, and transferred onto the transfer rail 10 of the rolled ball stocker 9.

Thus, the winding reel 5 and the winding ball 6 are wound around the side surface of the veneer veneer 1 on the unloading side by the cooperation between the winding guide belt 37 and the veneer veneer introduction member 29, and the winding guide member 64 Since the veneer veneer 1 is wrapped around the veneer veneer 1 from its outer peripheral upper surface to the vicinity of the introduction port of the veneer veneer 1, the veneer veneer 1 being conveyed is automatically introduced into the take-up reel 5 and wound up.

"Effects" According to the present invention, as described below, when winding a continuous veneer veneer, the increasing distance from the surface of the winding ball is maintained at a constant distance to the opposing tape guide body.
By passing a heat-fusible tape fed out from a tape reel and supplying air to the tape just before the end of winding the winding ball, the tip of the tape is wound around the winding ball and the tape is applied multiple times to the winding ball. The tape is wound, and then the heating element is advanced to the surface of the rolled ball to press the tape wound around the outer periphery of the rolled ball with a tape presser, and the outer tape and the inner tape are used as a heating source. Since the tape is welded and secured to the rolled ball, it is possible to automatically feed the tape to the rolled ball and heat weld it from close range in a short time.
The drawbacks of the conventional methods described above can be eliminated.

Furthermore, when welding the inner and outer tapes to each other using the heating source of the heating element, by pressing the tape wound around the outer periphery of the rolled ball with a tape presser from a position near the heating source, the rolled ball can be The tape, which had been under tension in the tangential direction between the outer periphery of the tape guide and the tip of the tape guide, can be welded after being made to follow the outer periphery of the rolled ball. This eliminates the inconvenience of the heating source touching the tape under tension on the way to the surface and causing the tape to melt before it is latched. Unwinding from the section is avoided.
