This invention relates to a curl stretching device that spreads out curls that occur at the tip of a cut veneer at the beginning of peeling in an automatic winding machine.

のである。 In general, the continuous band-shaped veneer veneer that is cut and discharged with a veneer lace has its tip curled upward on the conveyor, so it is wrapped in single and double layers on the conveyor before it reaches the wrapping position. Since the ball is curled, if it is wound as is on the take-up reel of an automatic winding machine, the single and double curls will be crushed and a significant step will be created on the surface of the wound ball on the take-up reel. Because of this level difference, not only does the winding roll that is in contact with the surface move violently up and down, but also the winding roller chain of the automatic winding machine that wraps around the outer circumference of the winding roll is subject to vibrations. There was a defect that the winding operation could not be performed smoothly due to the effect of stretching force, and another defect was that the curl at the tip of the veneer veneer was crushed and damaged, reducing the yield. The present invention was devised in order to improve the above-mentioned defects, and the present invention has been devised to improve the above-mentioned defects, and is to replace the said incoming conveyor with a drawing conveyor that alternately switches between a speed that is synchronized with the incoming conveyor and a speed that is approximately twice as fast as that of the incoming conveyor. The object of the present invention is to provide a device that automatically uncurls the tip of a veneer veneer by installing the device at a certain distance above the device.

れるように遅延切換制御されるものである。(Structure of the Invention) The present invention is a curl stretching device capable of achieving the above object, and an example of its implementation will be described as follows with reference to the drawings. An automatic winding machine is installed at the end of the carry-in conveyor 1 connected to the veneer race to support the tip of a chain 2a with winding rollers and to freely wind it around the outer periphery of a winding reel 2b.
2 are arranged. Above the carrying-in conveyor 1 near the automatic winding machine 2 , there is a space provided at a certain distance,
For example, stretching conveyors 3 having an appropriate length of about 1 to 1.5 m are installed in parallel at intervals of about 40 to 50 m/m. The drive shaft of the drawing conveyor 3 is connected to the drive shaft of the carry-in conveyor 1 via two drive systems with different speeds including two clutch devices 4a and 4b, and one of the drive shafts is connected to the drive shaft of the conveyor 1. On the clutch device side of the system, a speed increaser 5 such as a gear with an appropriate ratio, for example, a ratio of about 2:1 is inserted in the drive system on the clutch device 4b side in the case shown in the figure. The device is capable of driving the conveyor 3 alternately at a synchronized speed V 1 and a speed V 2 that is about twice that speed.
On the other hand, each time the curled tip of the veneer veneer 6 flowing on the carrying-in conveyor 1 is detected by a detector 7 such as a photoelectric switch, the detection signal of the detector 7 is transmitted to the two clutch devices 4a and 4b. The detection signal of the first tip actuates the clutch device 4b at the speed V2 on the speed increasing side, and then, after a set time limit of a delay device 8 such as a timer, the flow normally flows on the inlet conveyor 1. When the tip of the veneer veneer 6 reaches the automatic wrapping machine 2 in the latter stage,
The delay switching control is performed so that the clutch device 4a is switched again to the side of the clutch device 4a, which is driven at a speed V1 synchronized with the speed of the carry-in conveyor 1.

ある。 Therefore, as shown in FIG.
The carry-in conveyor 1 and the drawing conveyor 3 are driven at the same speed V1, and then, at the same time as the tip of the veneer veneer 6 passes directly under the detector 7, the drawing conveyor 3 is driven at the second speed. As shown in the figure, the speed is switched to V2 , which is about double the speed set by the speed increaser 5, and the veneer veneer 6 The curl at the tip is instantly stretched, and as is shown in FIG. 3, it is delivered to the automatic winding machine 2 and wound around the take-up reel 2b. In this case, a slight gap is forced to be formed between the stretching conveyor 3 and the winding place of the automatic winding machine 2 because the rolls are wound into thick rolls, but normally the veneer veneer 6
is transported at a high speed of about 100 to 300 meters per minute,
If the gap is small, the curl returns slowly, so there is almost no negative effect, but if the gap is large, the curl returns and causes the problem again, so in such cases, By constructing a guiding member 9 such as a round bar so as to protrude from the end of the stretching conveyor 3 toward the automatic winding machine 2 , safe delivery can be achieved.

Since the take-up reel 2h is supplied, the reciprocating device 2c such as an air cylinder is activated after the take-up reel 2b is supplied.
The reciprocating device 2c moves the rack 2d and the gear 2.
The turning mechanism of the bending arm 2g consisting of e is activated to wind the winding roller chain 2a around the take-up reel 2b, and the air cylinder 2i mounted on the bending arm 2g is also actuated to bend the bending arm 2g. Arm 2
f, the tip of the winding roller chain 2a is operated to pass over the top of the winding reel 2b and close to the carry-in conveyor 1, so that the winding chain 2a reaches the winding place. The veneer veneer 6 whose tip has been curled is immediately wound around the outer periphery of the winding reel 2b and wound into a thick roll as it is.

である。(Effect of the invention) As mentioned above, the device of the present invention carries out the carrying-in conveyor 3, which alternately switches between the speed V 1 synchronized with the carrying-in conveyor 1 and the speed V 2 which is approximately twice as fast as the carrying-in conveyor 1. This device automatically stretches the curls at the tips of the veneer veneers 6 installed at some intervals on the conveyor 1, so unlike conventional devices, single or double curls are avoided during wrapping. The rolled ball is not wound onto the take-up reel in a crushed form, resulting in significant steps on the surface of the rolled ball, which prevents smooth winding. This is an extremely effective device that has been able to eliminate all the defects that were causing a significant decrease in yield.
