Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has nine take-up reels driven by a side drive roll, and winds up a veneer veneer cut with a veneer lace and transported by a carry-in conveyor onto this take-up reel.
As the diameter of the veneer increases, the pressure of the veneer swings the incoming conveyor downward, and the veneer is rolled up in sequence! This invention relates to improvements to the II device.

Conventionally, the veneer veneer take-out conveyor 1 and delivery conveyor 2 have been provided as winding devices for veneer veneers.
In order to synchronize the cutting speed of the veneer veneer S with the cutting speed of the veneer veneer S, the electric signal of the potentiotor 5 connected to the step 9 screw 4 of the veneer race 3 and the electric signal of the tachometer 8 connected to the spindle 7 via the drive shaft 6 are transmitted. A synchronized motor 11 which is calculated in the control panel 9 and whose rotation is controlled by the output signal and the fine adjustment circuit 10 is connected to the veneer veneer take-out conveyor 1 and the carry-in conveyor 2, and the side drive roll 12 is carried in via the chain IA7. A drive system was adopted in which it was connected to conveyor 2 and rotated.

However, since the side drive blower tv1z and the carry-in conveyor 2 are connected by the chain 13, the side drive blower = I12 and the veneer veneer S transfer speed of the 6-person conveyor 2 are always set at a constant ratio. .

Normally, the 11J speed is set to be slightly faster than the latter, and is set to an arbitrary constant ratio of 1.02 to 1.04:1, for example.

Therefore, the thickness of the veneer veneer S, the veneer veneer S.

If the followability of the take-up reel 14 to the side drive roll 12 changes due to the strength of the waist, the veneer veneer S may be torn during winding, or the veneer taken up on the take-up reel 14 may be damaged. Since the veneer S is double, the yield decreases,
Otherwise, it became an obstacle when being rewound and fed to the next process.

The present invention has been made in view of the above problems, and the conventional device keeps the transfer speed of the veneer veneer S of the carry-in conveyor 2 and the surface speed ratio of the side drive roll 12 constant at all times, and makes the take-up reel 14 fully driven. In contrast, with this method, the speed ratio can be selected as appropriate depending on the width of the veneer veneer, the stiffness of the veneer veneer, etc., and the take-up reel is synchronized with the cutting speed.
It is configured to ensure reliable winding without eliminating the tearing of the veneer veneer during winding and the sagging of the veneer veneer after being wound on the take-up reel.

An embodiment of the present invention will be described below with reference to the accompanying drawing V, starting with its configuration.

20 is a take-out conveyor that supplies the veneer veneer S cut with a veneer knife 21 to an in-carrying conveyor 22, and the in-coming conveyor 22 loosely fits its starting end gooley 24 into the terminal end pulley shaft 23 of the take-out conveyor 20; A plurality of belts 26 are suspended between the starting end pulley 24 and a terminal end pulley 25 arranged oppositely at appropriate intervals, and are rotated at the same speed and in the same direction as the take-out conveyor 20.

27 is a chain connecting the terminal end pulley shaft 23 of the take-out conveyor 20 and the terminal end pulley shaft 28 of the carry-in conveyor 22; 29 is provided opposite the terminal end boo 925 of the carry-in conveyor 22 at an appropriate interval, and is interlocked with the carry-in conveyor 22; 80 is a frame on which the pulley shaft 23, the googly shaft 28 and the side drive roll 29 are rotated, and the tip swings up and down with the gooly @ 2B as a fulcrum; 81 is the outer periphery F-plane of the seventh A take-up reel 32 is brought into contact with the upper surface of the outer periphery of the side drive roll 29 to wind up the veneer veneer St.
is connected to the Gooley shaft 28 and its output shaft 3.
5 is a transmission connected to the side drive roll 29 via a chain 36; 37 is an output shaft 85 of the transmission 32;
38 is a spindle rotational speed detector connected to the spindle 4o via a drive 4Qt19, 41 is screwed into a frustum 43 to which a veneer knife 42 is attached, A stepping screw 44 is connected to the spindle 40 or the drive shaft 39 via a gear box (not shown) and moves the veneer knife 42 back and forth with respect to the spindle 4o, and 44 is a veneer knife connected to the stepping screw 41. A log diameter detector 42 detects the cutting position, 45 is a tuned motor connected to the pulley shaft 23, a spindle rotation speed detector 88, and a log diameter detector #44
It is connected via a gill adjustment circuit 47 to a control panel 46 which calculates i'C1 and outputs a full rotation control signal.

In this embodiment, a transmission 32 is interposed between the carry-in conveyor 22 and the side drive roll 29, and the speed ratio of the surface speed of the side drive roll I and the veneer veneer S transfer speed VC of the carry-in conveyor 22 is adjusted appropriately. However, as an alternative to this, as shown in Fig. 3, the synchronized motor 45 and the variable speed motor 48 for driving the side drive roll 29 are operated synchronously, and further adjusted to follow the variable speed motor 48. circuit 4
9 can also be provided to control the rotation of the side drive roll 29.

In addition, a rotation speed detector is connected to the pulley shaft 28, and the electrical signal of this rotation speed detector is calculated to drive a control panel that outputs a rotation control signal and a variable speed motor whose rotation is controlled by a copying adjustment circuit. It is also possible to connect directly to the roll 29.

Next, the effect will be explained.

When winding up the continuous veneer veneer S, the feed screw 41 is rotated as the veneer lace 21 cuts the veneer veneer S.
A log diameter cooker 44 connected to the feeder V screw 41 outputs an electrical signal proportional to the diameter of the log being cut to a control panel 46.

In addition, since the spindle rotation i11 detector 88 outputs an electric signal proportional to the rotation speed of the log to the control panel 46,
The control panel 46 calculates these electrical signals and controls the image adjustment circuit 47.
A rotation control signal is output to the tuned motor 45 via the motor.

Therefore, the veneer veneer take-out conveyor 20 and the carry-in conveyor 22 connected to the synchronized motor 45 supply the veneer veneer S to the take-up reel 81 at the same speed as the veneer veneer S cutting speed.

In addition, the side drive roll 29 is connected to a carry-in conveyor 220.
Along with the rotation, it is rotated via the transmission 32, causing the take-up reel 31 to follow.

In this case, the surface speed v2 of the side drive roll 29 is determined by the operation panel 37 of the transmission 32 to an appropriate speed ratio, e.g. ”'C$nHaVl :'V2
= 1:l.

0.6 HM<S<1.2 jllfa>nhaVl
:V2=l: 1.02, if S 1.2 n, then Vl:V2= 1: l・04, so the 4 reel 31 is fed by the conveyor 22.
It is possible to complete the winding process by winding up all the veneer veneers S at the same speed as the cutting speed, and sequentially winding up to an appropriate diameter, for example, 1UOOJll.

As described above, according to the present invention, when cutting a veneer veneer for veneer lace, during winding, the log diameter detector outputs an electric signal indicating the log diameter, and the spindle rotation speed detector outputs an electric signal indicating the log rotation speed. No. 100 is output to the control panel, these signals are calculated in the control panel, and the rotation control signal is output to the synchronized motor via the image adjustment circuit, so the take-out conveyor and the carry-in conveyor can control the veneer veneer cutting speed. The veneer veneer is fed to the take-up reel at the same speed.

Furthermore, the take-up reel is interlocked with the carry-in conveyor, and the site drive is set at an appropriate m degree ratio with respect to the veneer veneer transfer speed VC of the carry-in conveyor by means of a transmission.
Since the veneer is driven by the veneer, the veneer veneer supplied by the conveyor can be wound up at the same speed as the veneer veneer cutting speed.

Therefore, the tearing of the veneer veneer during transportation, the winding υ reel y
This eliminates the tab sticking of the unrolled veneer veneer (while still being able to be rolled up, it prevents low yields, and also eliminates obstacles when unwinding and feeding to the next process machine. Work efficiency can be completely improved.
