Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a veneer veneer that is cut with a veneer lace and automatically supplies the tip edge of a veneer veneer that is transported by an incoming conveyor to a take-up reel so that it can be wound up one after another. This invention relates to a veneer winding device.

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 leading edge of the succeeding 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.

The present invention aims to improve the conventional inefficient manual work by linking a veneer veneer introduction member to a plurality of take-up guide conveyor belts stretched along the outer peripheral surface of the take-up reel. , The front edge of continuous veneer veneer is automatically introduced and wound onto the take-up reel or roll, and irregular length veneer veneers and small width veneers that cannot be wound on the take-up reel such as top peeling and core peeling. The veneer is configured to be passed through a take-up reel and transported out of the machine by a take-up guide conveyor and a veneer veneer delivery conveyor.

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 a pulley shaft 12 at the start end of the veneer S of the carry-in conveyor 11 on the carry-in side; The veneer veneer S is placed between the installed side drive rolls 15.

I'm hanging on to 6.

17 is a pressing fluid cylinder to which one end of a chain 18 for suspending the pedestal 10 is connected; 19 is a compressing fluid cylinder that overcomes the pressing force of the pressing fluid cylinder 17 and urges the pedestal 10 downward; 20 is its outer periphery. A take-up reel 21 whose lower surface is brought into contact with the upper surface of the outer periphery of the side drive roll 15 and is driven to wind up the veneer veneer S. A take-up reel 21 is horizontally suspended parallel to the take-up reel 20 at an appropriate position in front of the pedestal 10. is a machine frame connected to the discharge conveyor elevating fluid cylinder 22, 23 is a plurality of columns that are erected on the machine frame 21, and whose upper ends are swung back and forth using a spring 24 as a fulcrum near the lower end; A straight beam that is pivotally supported at the upper end of the support column 23 so as to be tilted toward the veneer veneer S discharge side, and discharges irregular length veneer veneers and narrow veneer veneers transferred by the carry-in conveyor 11 to the outside of the machine. 26 is a stopper of the veneer veneer conveyor 25 fixed to the pillar 23, and 27 is a veneer veneer conveyor with a plurality of rollers arranged in a staggered manner on the left and right sides of the veneer veneer. ,
A pressure roll 28 is located at the tip of the veneer veneer delivery conveyor 25, forms a part of the delivery conveyor, and rotatably contacts and pressurizes the outer peripheral surface of the rolled bobbin.
is a plurality of veneer veneers that are pivotally supported on a frame 10, one end of which is locked to a lower winding drum 29 containing a built-in tension member, and the other end of which is locked to the pressure roll 27 through a guide body 30. The introduction member 31 is loosely fitted to the tip of a swinging arm 33 that is pivotally supported on a bracket 32 on the pedestal 10, and is connected to a pressurized fluid cylinder 35 via a connecting arm 34, and is connected to the veneer unit of the take-up reel 20. A pressure pulley 36 that urges the side surface on the discharge side of the plate S is rotated between the side drive roll 15 and the pressure pulley 31 at the same speed and in the same direction as the carry-in conveyor 11, and is rotated in the same direction as the take-up reel 2.
A winding guide conveyor is made up of a plurality of belts 37 that are wound around the lower side of the unloading side of the veneer veneer S, and 38 is a tension pulley that tensions the belts 37.

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 the narrow veneer veneer that are cut out at the beginning and end of the raw wood cutting, which cannot be rolled up, are first rolled up. Let's talk about the treatment of the board.

The carry-in conveyor 11 and the take-up guide conveyor 36 are swung downward together with the frame 10 by the reduction fluid cylinder 19, so that the carry-in conveyor 11 is brought into a substantially horizontal state.

The pressurized fluid cylinder 35 also forces the belt 37 of the take-up guide conveyor 36 into a substantially horizontal position.

Furthermore, the veneer veneer carrying out conveyor 25 is lowered by the carrying out conveyor lifting/lowering fluid cylinder 22,
The height should be approximately the same as that of the carry-in conveyor 11.

Random length veneer veneers or narrow veneer veneers transferred by the carry-in conveyor 11 pass through the take-up reel 20, and are sequentially discharged outside the machine by the take-up guide conveyor 36 and the veneer veneer carry-out conveyor 25. be done.

After the irregular length veneer veneer and narrow veneer veneer are discharged from the machine, the driving of the veneer race, the carry-in conveyor 11, and the take-up guide conveyor 36 is temporarily stopped, and during this time the pedestal 10, the veneer veneer carry-out conveyor 25, and the take-up guide are stopped. Each conveyor 36 is returned to its original state as described below.

That is, the terminal end of the gantry 10 is swung upward by the pressing fluid cylinder 17 about the pulley shaft 12 as a fulcrum, and presses the upper outer surface of the side drive roll 15 against the lower outer surface of the take-up reel 20.

On the other hand, the pressurizing pulley 31 is connected to the pressurizing fluid cylinder 3
5 toward the outer circumferential side of the take-up reel 20, and the belt 37 is stretched along the lower side of the outer circumferential side of the take-up reel 20.

Further, the veneer veneer conveyor 25 is lifted by the conveyor elevating fluid cylinder 22, and the pressure roll 27 is disposed opposite to the side surface of the take-up reel 20 at an appropriate interval, and the veneer veneer introduction member 28 is moved to the guide body 3.
0 to the lower winding drum 29.

After the return, due to the actual peeling and cutting, the carry-in conveyor 11
The continuous veneer veneer S transported by is supplied to the take-up reel 20, and its front edge is introduced by a belt 37 that surrounds the lower side of the take-up reel 20 on the delivery side of the veneer veneer S. It is wound up sequentially.

During winding, as the diameter of the rolled ball increases, the rolling force of the rolled ball overcomes the pressing force of the pressurized fluid cylinder 17, so that the pedestal 10 is sequentially swung downward.

In addition, as the diameter of the winding ball increases, the pedestal 10 is swung downward, so the pressure pulley 31, which was initially urging the vicinity of the center A of the side surface of the winding reel 20, is pushed forward by the winding ball. The winding guide conveyor 36 is swung downward together with the frame 10.

Therefore, the range of the belt 37 that surrounds the winding ball is moved downward.

On the other hand, the pressure roll 27, which was installed opposite to the vicinity of the center B of the side surface of the take-up reel 20, has a winding ball having an appropriate diameter, e.g.
When the diameter of the rolled ball reaches 190 to 200 mm, the ball is pressed and sequentially swings forward as the diameter of the rolled ball increases.

As the pedestal 10 is swung downward and the pressure roll 27 is swung forward, the veneer veneer introduction member 28 is sequentially unwound from the lower winding drum 29 and comes to wrap around the outer circumferential surface of the rolled ball.

In this case, the guide body 30, the lower winding drum 29 is set, the continuous veneer veneer S has the minimum diameter, that is, the diameter of the take-up reel 20, due to the cooperative action of the winding guide conveyor 36 and the veneer veneer introduction member 28, for example,
At any diameter from 170 mm to an appropriate maximum diameter of 1000 mm, the front edge is smoothly and reliably introduced to complete the winding.

After winding is completed, the rolled balls are transported to the stock warehouse.
The frame 10, the veneer veneer discharge conveyor 25, and the winding guide conveyor 36 are returned to their original states, and the winding reel 20 is supplied.

Note that the veneer veneer introduction member 28 in this embodiment
uses a chain with rollers, and the links are made of plastic to reduce weight, but they may also be made of iron, aluminum, etc.

In this chain with rollers, since the roller portion comes into contact with 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 up, and the configuration becomes complicated. Therefore, in this embodiment, a chain with rollers is more suitable.

As described above, according to the present invention, the winding reel and the winding bobbin are wrapped around the lower side of the veneer veneer delivery side by the cooperation between the winding guide conveyor and the veneer veneer introduction member, so that they are conveyed at high speed. The continuous veneer veneer that comes is automatically introduced along the outer circumference without stopping the veneer race and the conveyor, its front edge is held by the winding guide conveyor and the veneer veneer introduction member at any diameter. and wrapped.

In addition, irregular length veneer veneers and narrow veneer veneers that cannot be wound onto the take-up reel are passed through the take-up reel and quickly transported out of the machine by the take-up guide conveyor and veneer veneer conveyor. Therefore, the manual work that conventionally involved stopping and winding by hand can be completely eliminated, improving work efficiency.
