Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for automatically bundling veneer sheets and an apparatus for carrying out the method.

[Prior Art] Conventionally, in the production of veneers, logs are cut with a rotary race, and continuous veneers are obtained until the logs become approximately perfect circles. The strip-shaped continuous veneer obtained by cutting the log into a substantially perfect circle is continuously wound onto a reel by a winding device to form a rolled veneer.

As for the winding device, Jikosho 53-29750, Jitsukisho
55-13043, JP 54-32606, JP 55-49205,
Many proposals have been made, including Special Public Interest Publication No. 54-40602.

Many measures have been taken to streamline the process of winding the strip-shaped continuous veneer conveyed by these winding devices onto a reel to form a veneer roll. The veneer-wound ball is bound by the worker's hands by wrapping a rubber band string or the like around the outer periphery of the veneer-wound ball, or by driving a peg into it to prevent the veneer-wound ball from unraveling, and then the next step is carried out. was being transported to. For this reason, even though the work of winding continuous veneer onto a reel has been streamlined, a worker is always required to tie the veneer to prevent it from unraveling, and although the work of the worker has been reduced, it has completely saved labor. remained unfulfilled.

The present invention addresses such problems in conventional veneer manufacturing, and in particular proposes an automatic binding method for veneer windings, thereby dramatically streamlining the veneer manufacturing process.

Embodiments of the present invention illustrated in the drawings will be described below.

[Description of Examples] As shown in Fig. 1, a continuous veneer 1 cut with a rotary race is conveyed by a conveyor 2, and continuously reeled by an arbitrary winding device (not shown). 3 to form a veneer-rolled ball 4.

Immediately before the reel 3, the linear material 5 is inserted into the winding part 4a which is the boundary between the unwinding part 1a and the already wound ball 4 above the conveyor 2. A linear material discharge device 6 is provided for this purpose.
Therefore, the linear material discharging device 6 has the winding section 4a.
oriented towards.

As shown in FIG. 6, the linear object discharge device 6 has an air inlet 7 for air sent through a solenoid valve v.
It consists of an outer frame 9 having a linear object insertion opening 8, and a piston 13.

As shown in Fig. 6, the piston 13 has a piston rod 13a that penetrates the linear object passage hole 10 inside thereof, and a notch 11 (Figs. 2 and 6) is formed at the tip of the piston rod 13a, which extends outward. The so-called tapered heads 12, which have a shape that gradually expands, are aligned.

The piston rod 13a is located in the piston chamber 14 within the outer frame 9.
The head 12 is always held by the spring 14 housed in a.
is being towed so as to be stored with the notch 11 closed. The linear object 5 is placed in a linear object discharge device 6 in advance.
It passes through the linear object insertion opening 8 in the outer frame of the piston 13 and into the linear object passage hole 10 in the piston 13.

[Description of operation of the present invention] The operation of the present invention will be explained below.

Immediately before the end of winding the continuous veneer 4, the solenoid valve v
is activated, and air is sent into the linear material discharge device 6 through the air insertion port 7.

The piston 13 in the linear object discharging device 6 is compressed by the spring 14 due to the pressure of the air, and the head 12 is caused to project out of the device 6.

Due to the protrusion of the head 12 of the piston 13, the head 12 is pushed out from the notch 15 at the tip and the notch 11 of the head 12, which had been closed until then, is opened. Then, the air is piston 13
Since the air passes through the linear material passage hole 10 and is discharged to the outside, the linear material passage hole 10
The linear objects 5 passed inside are simultaneously and continuously discharged.

The linear material 5 discharged from the linear material discharging device 6 is inserted into the winding section 4a, which is the boundary between the unwinding section 1a immediately before the end of winding and the wound ball 4 that has already been wound, and is inserted into a continuous unit Simultaneously with the plate 1, the linear material 5 is continuously pulled out by the winding ball 5a as the veneer winding ball 4 rotates.

After the winding of the continuous veneer 1 is completed, the veneer winding ball 4 is idled, and the linear material 5 is wound around the outer surface of the winding ball 4 a plurality of times.

At the same time as the winding of the linear object 5 is completed, the solenoid valve v is activated to stop the supply of air to the linear object discharge device 6. As a result of stopping the air supply, the head 12 is housed in the notch 15 at the tip end of the piston 13 due to the restoring force of the spring 14. Then, the cut 11 is closed, the head 12 pinches the linear object 5, and the linear object 5 is cut by the tension generated by the rotation of the veneer winding ball 4.

In this way, the veneer roll 4 is bound by the linear material 5 and transported out. The linear object 5 refers to a long continuous object, regardless of its shape, such as a linear shape, a band shape, or a chain shape, which has an adhesive part at least in the part that contacts the veneer roll. For example, adhesive tape
Use duct tape, adhesive paper coated with adhesive, filament paper, etc. In short, any material that can be automatically bonded to the outer peripheral surface of the veneer after being wound around the veneer 4 is sufficient.

Thereafter, the discharging of the linear material 5 and the feeding of air are repeated in the same manner.

Air pressure may be used instead of the spring 14.

When an adhesive tape is used as the linear material 5 and its discharge is performed at the same time as the continuous veneer 1 starts being wound onto the reel 3, the centrifugal force generated when the continuous veneer 1 winding ball 4 rotates causes the adhesive tape to stick to the veneer. 1, the veneer 1 can be prevented from tearing, and can be reinforced with adhesive tape.

[Operations and Effects of the Present Invention] The veneer-wound ball 4 can be automatically bundled at the same time as the veneer-wound ball 4 is wound onto the reel 3.

The wire material 5 is one that can be adhered to the outer circumference of the veneer winding ball 4, and since it is wound several times, the winding ball 4
You can definitely prevent it from fraying.

In the present invention, the rotating winding part 4a, which is the boundary between the unwinding part 1a of the continuous veneer 1 immediately before the end of winding and the winding ball 4 that has already been wound, is directed toward the winding part 4a. Linear object 5 from linear object discharge device 6
automatically inserted. Therefore, since the linear material 5 is wrapped around a small portion of the outer periphery of the wound ball 4, the wound ball 4 is not damaged and the time required for binding can be shortened.

Since a head 12 is attached to the linear material discharging device 6 to stop the linear material 5 at the time of completion of discharging the linear material 5, the wire material 5 can be automatically cut by the tension generated by the rotation of the winding ball 4.
