Description

[Detailed Description of the Invention] The present invention automatically supplies the front edge of continuous veneer veneer cut with a veneer lace and transported by an incoming conveyor to a winding reel, so that it can be wound up one after another. This invention relates to a winding device for veneer veneer.

Conventionally, this type of work has been carried out by temporarily stopping the veneer race, the veneer veneer conveyor 1 and the side drive roll 2, and manually rolling the front edge of the veneer onto the outer peripheral surface of the take-up reel 3, as shown in Fig. 1. A method was adopted in which winding and cutting were restarted after winding, and winding was performed sequentially.

However, since the veneer veneer is transported perpendicular to the fiber direction and has many cracks, it is easily torn. The roll 2 had to be temporarily stopped and the front edge of the following veneer veneer had to be manually wrapped around the outer circumferential surface again, which required manual labor each time and caused a significant drop in work efficiency.

In order to improve the conventional inefficient manual work, the present invention winds up the front edge of a continuous plywood veneer using a plurality of winding guide members stretched along the outer peripheral surface of a winding reel. It is wound along the outer periphery of the reel or bobbin, and irregular length veneer veneers and narrow veneer veneers that cannot be wound on the take-up reel, such as top peeling and core peeling, are passed through the take-up reel and taken out of the machine. It is constructed so that it can be discharged.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.
First, its configuration will be explained.

Reference numeral 10 denotes a frame whose terminal end swings up and down about the veneer veneer S carrying-in side starting part pulley shaft 12 of the carrying-in conveyor 11; A plurality of belts 16 are suspended between the drive rolls 15 and rotated at the same speed as the cutting speed of the veneer veneer S.

A pressure body 40 is connected to the swing frame 32 and is loosely fitted to the tip of the pressure arm 39 that swings back and forth, and urges the side surface of the take-up reel 20 on the unloading side of the veneer veneer S. An upper winding drum 41 which is pivotally supported and has a built-in tension member has one end locked to the upper winding drum 40, and the other end is connected to the outer circumferential upper surface of the winding reel 20 via a pressurizing body 37. is,
This is a plurality of winding guide members that are locked to the pressure roll 29.

Next, the action will be explained.

First, before winding up the continuous veneer veneer S that is transported by the actual peeling of the raw wood, the irregular length veneer veneer and small width veneer that are cut out at the initial and final stages of cutting the raw wood, which cannot be rolled up. Let's talk about the treatment of veneer.

The pedestal 10 is swung downward by the compressing fluid cylinder 19 to bring the carry-in conveyor 11 into a substantially horizontal state, and the sliding frame 24 is moved downward along the sliding guide 25.

Next, the sliding frame 24 is moved diagonally upward along the sliding guide body 25 by the sliding frame elevating fluid cylinder 23 to widen the distance between the pressure roll 29 and the upper surface of the belt 16.

Random length veneer veneers and narrow veneer veneers transported by the carry-in conveyor 11 pass through a press roll 29 and a take-up reel 20, and are sequentially discharged out of the machine.

After the irregular length veneer veneers and narrow veneer veneers are discharged from the machine, the veneer race and the carry-in conveyor 11 are once driven, during which time the pedestal 10 and the sliding frame 24 are returned to their original states as described below.

That is, the sliding frame 24 is lowered by the sliding frame lifting fluid cylinder 23.

Further, the terminal end of the frame 10 is swung upward by a pressing fluid cylinder 17 using the pulley shaft 12 as a fulcrum, and presses the upper peripheral surface of the side drive roll 15 against the lower peripheral surface of the take-up reel 20, and the pressing roll 29 It is biased toward the side of the take-up reel 20.

Further, the pressurizing body 37 is urged against the side surface of the take-up reel 20 by the pressurizing body pressing fluid cylinder 38, and the take-up guide member 41 is stretched along the outer circumferential upper surface of the take-up reel 20.

After the return, due to the actual peeling and cutting, the carry-in conveyor 11
The continuous veneer veneer S transported by
0 is sequentially wound along the outer periphery of the take-up reel 20 by the take-up guide member 41 that surrounds the upper surface of the outer periphery of the take-up reel 20 .

As the diameter of the rolled ball increases, the rolling force of the rolled ball overcomes the pressurizing force of the pressurizing fluid cylinder 17.
Sequentially swing downward.

Additionally, as the pedestal 10 is swung downward, the pressure roll 29, which was initially urging the vicinity of the center A of the veneer veneer S carry-in side side surface of the take-up reel 20, moves downward along the sliding guide 25. be done.

On the other hand, the veneer veneer S of the take-up reel 20 is moved by the pressure body pressing fluid cylinder 38 to the center B of the side surface on the unloading side.
As the diameter of the rolled ball increases, the pressurizing body 37, which has been urging the vicinity thereof, is pressed by the rolled ball and swings forward.

As the pressure roll 29 is moved downward and the pressure body 37 is swung forward, the winding guide member 41 is sequentially rewound from the upper winding drum 40 along the outer periphery of the rolled ball.

In this case, the amount of change in the biasing position of the pressurizing body 37 is minimized, and the pressure roll 29 is set to move diagonally downward as the pedestal 10 swings while biasing the rolled ball. The winding guide member 41 can always surround the winding ball from the upper surface of the outer periphery to the vicinity of the introduction port of the veneer veneer S, and the veneer veneer S has a minimum diameter, that is, the diameter of the winding reel 20, for example, 170 mm, up to a maximum diameter of, for example, 1000 mm as appropriate. The front end edge can be wrapped smoothly and reliably along the outer circumference at any diameter.

After winding is completed, the pressure arm 39 is rotated in the clockwise direction shown in FIG.
By rotating the swinging frame 32 clockwise about the sprocket shaft 33 according to the reduction degree of 4, the winding guide member 4 that was being wound from the top surface of the winding ball is removed.
1 is opened, the rolled balls are carried out to the stocker,
The pedestal 10 is returned to its original state.

After unloading, the take-up reel 20 is supplied and the swing frame 3 is
2. The pressurizing body 37 is returned to its original state.

Note that the winding guide member 41 in this embodiment uses a chain with rollers, and the link portion is made of plastic to reduce weight.
It may also be made of aluminum, etc.

In this chain with rollers, since the roller portion follows and contacts the winding ball, friction with the winding veneer is reduced and the winding veneer can be smoothly wound around the winding reel 20.

Also, a belt may be used instead of a chain with rollers, but in this case, friction cannot be reduced unless the belt rotates at the same speed as the veneer being wound, and multiple configurations are required. Therefore, in this embodiment, a chain with rollers is more suitable.

As described above, according to the present invention, since the winding reel and winding bobbin are surrounded by the winding guide member from the upper surface of the outer periphery to the vicinity of the veneer inlet, continuous veneer sheets transported at high speed are The front edge of the plate is held by the winding guide member at a desired diameter, and the plate is automatically wound along the outer periphery without once stopping the veneer race and the introduction conveyor.

In addition, irregular length veneer veneers and narrow veneer veneers that cannot be wound onto the take-up reel can be removed from the machine by raising the pressure roll, passing through the pressure roll and take-up reel, and being smoothly discharged from the machine. The work that used to be done manually is completely eliminated, improving work efficiency.
