The rolled balls 3 are wound onto the roll 2 until they become rolls 3 of an appropriate diameter, and after being stored once in the rolled ball stock area 4, or transported as they are to the end of the rolled ball stock area 4 on the transfer rack 5, they are then rewound. At position 6, both shafts of the winding reel 2 are supported by the reel receiver 8 fixed to the reel support 7, and then the unwinding conveyor 9 is brought into contact with the upper outer periphery of the winding reel 3 to rewind it. The cutting device in the stage process or the conveyor 128 connected to the net conveyor 11 of the veneer dryer 10 is transferred.

リヤ１４へ返送されることになる。That is, at the unwinding position 6 of the upper spool stocker 4, the relatively thin veneer veneer 1 for the original sheet is normally rewound to the upper net conveyor 11 of the veneer dryer 10.
The empty winding reel 2 that has been transferred and rewinded is returned to the reel stock area 14 from the upper unwinding position 6 through a return rack 13 extending diagonally downward, and is then returned to the lower unwinding position 6. In this case, the intermediate veneer veneer 1, which is usually about twice as thick as the original veneer 1, is rewound, and is transferred to the lower tier, which has a slower conveyance speed than the upper tier screws 1 to the conveyor 11. It is to be transferred to the net conveyor 11,
The empty winding reel 2 after being rewound is returned to the reel stock area 14 from the lower unwinding position 6 via a return rack 13 extending obliquely upward.

ベニヤ単板１の搬送速度を揃速制御させる必要がある。“Problem to be Solved by the Invention” Normally, in order to stably convey the veneer veneer 1 that is rewound from the rewound position 6 while being transferred onto the conveyor 12, it is necessary to It is necessary to uniformly control the conveyance speed of the veneer veneer 1 on the conveyor 12.

速制御が阻害されることがある。However, when the touch belt constituting the unwinding conveyor 9 is pressed against the winding ball 3 and the veneer veneer 1 is fed out by its frictional force, the frictional force cannot be reliably transmitted to the outer circumferential surface of the winding ball 3. Alternatively, when the veneer veneer 1 is transported onto the transport conveyor 12 after being rewound, mechanical errors caused by slips on the transport conveyor 12, etc. may impede uniform speed control of both.

。Furthermore, when the veneer veneer 1 is being rolled up, wet tape is pasted near both ends to reinforce the edges, but the edges of the veneer veneer 1 being rolled up are cracked and missing. If such cracks or chips are present, the cracks or chips will stick to the outer periphery of the wound ball 3 through the part, and if the part gets caught in the part during rewinding, the uniform speed control of both will be hindered.

を来すものである。When this uniform speed error occurs, the veneer veneer 1 that is continuously unwound from the winding bobbin 3 will be displaced either up or down on the conveyor 12. That is, when the circumferential speed of the conveyor 12 becomes faster than the unwinding speed, the veneer veneer 1 becomes pulled upwardly, and in an excessively stretched state, the veneer veneer 1 is torn in the direction of its fibers. On the other hand, if the veneer veneer 1 becomes too slow, the veneer veneer 1 will be in a slack state where it is displaced downward, and in an excessively slack state, the veneer veneer 1 will be transported folded over each other, and the veneer veneer 10, which is the next step, or cut. This provides support for processing operations in the device.
このため、従来より上記揃速誤差を修正すべく、巻戻さ
れるベニヤ単板１の上下に亘る変位量を検出して、巻戻
しコンベヤ９の周速を調整していた。For this reason, conventionally, in order to correct the speed uniformity error, the circumferential speed of the unwinding conveyor 9 has been adjusted by detecting the amount of vertical displacement of the veneer veneer 1 being rewound.

ベヤ９を増減速し、揃速誤差の解消を図っていた。Specifically, a limit switch is arranged on the conveyor 9, and a swingable lever attached to the tip of the limit switch is made to protrude from the conveying surface, so that the lever detects the veneer 1 in the process of being rewound. The unwinding conveyor 9 is increased or decelerated depending on whether or not the rewinding conveyor 9 is being used, thereby eliminating the uniform speed error.

ことは不可能であった。However, even in this conventional method, the winding ball 3 is rewound using the reel receiver 8 as a supporting part, and as the diameter of the winding ball 3 decreases, the displacement detection position moves, so reliable detection cannot be expected. However, it has still not been possible to completely eliminate the above-mentioned disadvantages.

ものである。"Means for Solving the Problems" In view of the above, the present invention provides that, at the veneer veneer unwinding position of the reel support, both end trochanter portions of the take-up reel with the winding ball wound thereon are held at the support portion. A rewinding conveyor is placed in contact with the upper part of the unloading side of the rolled balls, and a transport conveyor is provided below the rolled balls, while a cross beam is extended from the support to an appropriate position above the transport conveyor. A displacement detector for detecting the amount of displacement of the rewinding veneer is slidably arranged on the cross beam, and a command is given to increase/decelerate the variable speed motor of the rewinding conveyor in accordance with the detected amount of displacement. At the same time, the displacement detector is caused to follow and slide on the cross beam in accordance with the amount of decrease in the diameter of the rolled ball detected by the ball diameter detector.

ることになる。"Operation" By driving the unwinding conveyor, the veneer veneer is unwound from the roll and transferred onto the transport conveyor. During this transfer, the displacement amount detector detects the slack state of the veneer veneer, and based on this detection result, the variable speed motor of the unwinding conveyor is instructed to increase or slow down, and the speed decreases as the unwinding progresses. The displacement detector slides on the cross beam according to the diameter of the winding ball, and the relative distance between the displacement detector and the outer circumference of the winding ball is kept constant, so the veneer veneer normally has a moderate amount of slack. While being formed, it is conveyed on a conveyor.

The same numbers are given to the parts that have already been explained, and repeated explanations are omitted.9 Inside the pair of reel supports 7, there is installed a reel holder 8 that freely supports the rotor portions at both ends. A rewinding position 6 is formed above the reel receiver 8 by installing a reel holder that is swingable relative to the upper part of the trochanter. On the other hand, a plurality of pulleys are fitted to the shaft supported between the upper parts of the reel support 7 at arbitrary intervals,
A rewinding conveyor 9 on which a touch belt 15 is suspended is configured.

The speed of the rewinding conveyor 9 is uniformly controlled based on the speed of the transport conveyor 12.

ヤ単板１の位置を検出信号によって得るものである。Next, a support 22 is mounted on a cross beam 21 that projects from one side of the reel support 7 in the unwinding direction of the veneer veneer 1, and the rack, pinion, and ball screw are mounted on the cross beam 21 using the cross beam 21 as a sliding surface. , a non-contact type displacement detector 24 such as an ultrasonic wave or a phototube is connected to the support body 22 via a sliding device 23 such as a rodless cylinder. If this displacement detector 24 is, for example, an ultrasonic detector having a transmitting part and a receiving part, the transmitted wave reaches one surface of the plywood veneer in the middle of being unwound from the transmitting part, and is reflected to the receiving part. The position of the veneer veneer 1 is obtained from the detection signal based on the time required for the received wave.

位量を、電圧の増減として捉えるものである。This detection signal is once converted into a voltage and inputted to the proportional controller 25, and the proportional controller 25 converts the change in voltage with respect to the position of the veneer veneer 1, that is, the amount of vertical displacement of the veneer veneer 1, into a proportional characteristic. It can be seen as such. Specifically, the unwinding speed of the veneer veneer 1 is synchronized based on the circumferential speed of the conveyor 12, and the veneer veneer 1 is kept in the most stable state while forming an appropriate amount of slack. In order to proportionally control the conveyance, the amount of vertical displacement of the veneer veneer 1 caused by speed uniformity errors is captured as an increase or decrease in voltage.

When the state is reached, the voltage amount is taken as a positive direction and becomes a speed-up signal.

This is to stably transport the veneer veneer 1.

対的距離を一定に保持させるものである。On the other hand, in order to detect the diameter of the rolled ball 3, a non-contact type winding diameter detector 27 such as an ultrasonic wave or a phototube as described above is arranged at a position separated from the rolled ball 3 by an appropriate distance, and The diameter of the winding ball 3 that decreases due to unwinding of the veneer veneer 1 is sequentially detected into the controller 28 into which the position detection signal of 22 is inputted, and this amount of decrease is converted into a detection signal as described above. ,
By operating the sliding device 23, the support body 22 is slid an equal distance toward the winding ball 3, and the relative distance between the displacement detector 24 and the outer periphery of the winding ball 3 is maintained constant.

7, but instead of this, an encoder for angle detection is attached to the shaft at one end of the rewinding conveyor 9, and by detecting the angle, the decrease in the number of rolled balls 3 is calculated. In some cases.
