連接している搬出コンベヤｉｔへ移乗させている。``Prior Art'' Conventionally, as shown in FIG. 6, a veneer veneer 1 cut by a heni A race is placed in a rotating roll 2 having an appropriate diameter in pressure contact with a site tribe roll at a winding position. The rolled ball 3 is rolled up and placed in the rolled ball stock area 4.
The reel 2 is temporarily stored at the reel 2 or transported as it is to the end of the reel stock area 4, and then at the unwinding position 5, both wheels of the reel 2 are supported on the reel receiver 7 fixed to the reel support 6, and then the reel 2 is unwound. Touch belt 8 on the upper outer circumference of ball 3
are brought into contact with each other, rewound, and transferred to a discharge conveyor IT connected to a conveyor 10 of the drying device 9.

なる。That is, at the unwinding position 5 of the upper rolled ball stock area 4, the relatively thin veneer veneer 1 for the original sheet is normally unwound and transferred to the upper transport conveyor IO of the drying device 9, and the rolled ball stock area 4 is unwinded. The empty reel 2 after being returned is returned from the upper rewinding position 5 to the reel stock area 13 via a return rack 12 extending diagonally downward, and at the lower rewinding position 5,
Normally, the veneer veneer l for the middle plate, which is approximately twice as thick as the veneer veneer 1 for the original plate, is rewound and transferred to the lower conveyor 1, which has a slower conveyance speed than the upper conveyor 10.
0, and the empty reel 2 after rewinding is returned to the reel stock area 13 from the lower unwinding 1 position 5 through the reel return rack 12 that extends diagonally. .

送されるまで、はぼ自重で落下する状態となり、非常に
不安定となる。"Problems to be Solved by the Invention" However, the veneer veneer l being rewound from the unwinding position 5 is in a state of falling under its own weight until it is transferred onto the carry-out conveyor 11 and is stably conveyed. This makes it extremely unstable.

比してほぼ倍の厚みを有していても、上記記載と同様に
、繊維方向に亘って裂断しやすい傾向がある。When this falls, for example, in the relatively thin veneer veneer I in the upper row, the resin streaks and dry cracks that occur in the fiber direction tend to tear, and in the lower row, - Even with raw wood, we roll up veneer veneer 1 cut from low-grade parts such as sapwood and core wood, so even if it is almost twice as thick as the upper layer, it will not meet the above description. Similarly, there is a tendency to tear easily across the fiber direction.

ていた。Furthermore, when winding a narrow veneer veneer l, it is easy to curl from the tip of the winding veneer and fall off due to its own weight, and it tends to be deviated and transported. If the veneer veneer 1 is once torn, broken, or transported in an uneven manner, the operator must unwind the veneer 1 or change the state of transportation. It became necessary to make corrections, which significantly hindered work efficiency.

ある。"Means for Solving the Problems" In view of the above, the present invention rotatably supports the rolled ball 3 of the veneer veneer 1 wound on the reel 2 with an appropriate diameter at the unwinding position 5. A rewinding guide member is wrapped around the lower outer periphery of the wound ball 3, and while a kite conveyor is brought into contact with the unwinding side of the wound ball 3, a rewinding roll that is in contact with the lower part of the wound ball 3 is driven. Then, air is supplied to the veneer veneer l at the unwinding position 5 of the winding ball 3, and the rewound veneer veneer l is transferred to the relay conveyor, thereby automating the unwinding.

ｉ１搬出側の外周に当接させる。Next, the rod 31 of the pushing fluid cylinder 38 is extended to bring the old upper guide pulley into contact with the upper outer periphery of the winding ball 3, and the contact pulley 51 is brought into contact with the veneer l1jf of the winding ball 3.
i1 Bring it into contact with the outer periphery of the unloading side.
従って、巻玉３は、その下部外周が巻戻し案内部材５３

一時的に吸着されることになる。While the winding ball 3 rotates at least once as the unwinding roll 21 is driven, the unwinding tip of the veneer veneer l reaches between the contact pulley 51 and the positioning pulley 55. At this time,
Since the air led out and supplied from the air outlet hole 50 becomes wider or deeper in diameter toward the tip of the lower opening, negative pressure is generated due to the diffusion of the air, and the tip of the veneer veneer l is unwound. , the air is temporarily attracted to the lower surface of the air guide member 36.

単板ｌの移乗を円滑としている。As the unwinding of the veneer veneer 1 progresses, the positioning pulley 55 of the moving member 33 moves forward following the decrease in the diameter of the spool 3, and along with this, the relay conveyor 56 also moves along the guide rail 60 at its starting end. slides on the pedestal 15 and moves forward, making the transfer of the veneer veneer l smooth.

る。In addition, during unwinding, if the plywood veneer 1 is torn from tar lines or dry cracks that occur in the M-phase direction, or if the width is small, the unwinding will be interrupted. Therefore, use a detector to confirm the absence of this plywood veneer l,
Air is again led out and supplied from the air lead-out guide 36, and the unwinding of the veneer veneer 10 is restarted as described above.

を一掃し、巻戻し作業の自動化を明し得るものである。"Effects" As described above, according to the present invention, the rolled ball 3 of the veneer veneer l wound with an appropriate diameter on the reel 2 is rotatably supported at the unwinding position 5, and the rolled ball 3 is rotatably supported at the unwinding position 5. The unwinding guide member 53 is wound around the outer periphery of the lower part, and the guide conveyor 35 is brought into contact with the upper unwinding side, and the unwinding roll 21 that contacts the lower part of the rolled ball 3 is driven, and in synchronization with this, the unwinding is performed. Since the air is supplied to the veneer funeral board l at the spring return position 5 of the ball 3, and the unwound veneer veneer l is transferred to the relay conveyor 56 in perfect synchronization, the impact when the page falls is alleviated, and the tar line is removed.
This prevents tearing from dry cracks, eliminates the need for the operator to unwind the veneer veneer l or to modify the conveyance conditions, and makes it possible to automate the unwinding work.

A veneer veneer roll wound with an appropriate diameter on a reel is rotatably supported at the unwinding position, and an unwinding guide member is wound around the outer periphery of the lower part of the rolled ball. Also, while the guide conveyor is in contact with the upper unwinding side, the unwinding roll that is in contact with the lower part of the winding ball is driven, and in synchronization with this, air is supplied to the plywood veneer at the unwinding part of the winding ball. A method for unwinding a rolled veneer veneer ball, characterized by transferring the rewound veneer veneer to a relay conveyor. 2. A carry-out conveyor is placed near the start end of the pedestal, and a rewind roll is placed near the end of the stand on which the end end is swingable with the start end of the veneer veneer transport side as a fulcrum. A reel of rolled balls is supported on a provided reel support, and a movable member is placed on a guide rail that protrudes toward the plywood veneer delivery side of this reel support so that it can move forward and backward with respect to the rolled ball. A guide conveyor that contacts the upper outer periphery of the veneer veneer discharge side and an air outlet guide body are installed in parallel at the section, and at the bottom of the movable member, the starting end is slidable on the pedestal. Endless unwinding guide members surrounding the terminal ends of the arranged relay conveyors and the lower outer periphery of the rolled balls each support one pulley that is supported under tension, and furthermore, this unwinding guide member is supported under tension. A method for unwinding a veneer veneer ball, characterized in that the other pulley is arranged so as to be swingable relative to the outer periphery of the ball.
