Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a veneer cutting machine such as a veneer lace or slicer to remove the completely flat tip of a continuous veneer that has curled upward due to back cracks formed when cutting the veneer. condition j
There is a device for feeding the yarn to the next process.

Traditionally, the yuzu strips for flooring have been stretched manually each time and then used for the next process.

However, manual processing has a limited processing speed, and
The veneer veneer, which flows at heavy speed, is temporarily stopped and stretched.
The co-phase with the next process was remarkable.

In order to reduce the damage caused by inefficient manual labor, the present invention automatically stretches out the curl at the leading end using a fast-forwarding action based on the speed diameter, and allows the lower belt to suck the product so that the trailing end remains flat. The structure is such that the curl can be supplied to the next process while eliminating the curl-enhancing effect due to the speed difference.

Hereinafter, an embodiment of the present invention will be explained based on the drawings, starting with its configuration.

A lower belt conveyor 5 is constructed by suspending several vents 2 with several air intake holes dispersed between pulleys 8, 40, and the front part of the first belt conveyor 5 is constructed. V, suction ducts 7 are arranged in close opposition to each other on the back side of the belt 2, and protrude from both sides of the pulley 3.
] Once the duct 8 is connected, it is discharged; the connection to the duct 9 is disconnected.

Alternatively, a cam-specific elevating means (Fig. 7J-, No. 7) can be used to provide a mechanism (7/) for the two-stage belt conveyor 18'.

A driving force that can be rotated from a power source that is unprecedented in history,
For example, the lower touch row conveyor 4 is arranged on one side of the conveyor 1, and the upper tray conveyor 1
When 3 falls to 1', it's day! A wave body, for example, the lower touch roll 15 that is aligned with one end of the J-11 axis is f4iJ-F
The touch roller 14 contacts or engages with the belt 2 and rotates in the same direction at a speed V (for example, 2 to 4 times faster than the cutting speed V of a veneer lace veneer) in the same direction.
When the seat conveyor 13 rises, the upper touch roll 15
174 is configured to release the contact between the lower cutter 7 and 14 and stop rotation.

In addition, a power source is installed in the frame of the two-stage belt conveyor ■3, and it is configured together with the upper belt conveyor 13,
When the upper stage belt conveyor 13 reaches l'111f, it is also possible to cut off the power source and cut the upper stage belt conveyor 13's rotation MvJt when it rises.

Next, I will explain the effect.

When conveying the continuous veneer veneer 16'Q, the upper belt conveyor 13 uses a lifting means such as a cylinder or cam to lift l-

It is rotating at a faster speed V1.

Continuous plywood veneer 1 with tip part a curled in two directions
6 is conveyed δ by the lower belt conveyor 5 in a direction that is equal to the direction of the fibers i1 and j.

When the ``tip end υ'' of the continuous veneer veneer 16 conveyed by the lower belt conveyor 5 comes into contact with the belt 12, it is unwound from the initial contact surface toward the mounting end C due to the speed difference v, -v. It is transported at a speed V while being moved.

As the unwinding progresses, the intake hole 1f of the belt 2: xffl
Due to the suction force of the suction duct 7 acting as

: The contact of the touch roll 14 is released and the rotation ff : is stopped, thereby eliminating the curl promoting effect and then supplying to the next process δ.

In addition, for irregular length plywood veneers, move the upper belt conveyor 13 to -F.
The next process, for example, is to pass through the winding reel of the veneer winding device and be continuously discharged.

As described above, according to the present invention, the upper belt conveyor and the
Due to the combined effect of the curl unwinding effect due to rapid feeding using the speed difference of the multi-tier belt conveyor and the suction force generated by the exhaust fan, the upward curl of the tip of the continuous plywood veneer being conveyed at high speed is caused by the first contact surface.

It is possible to feed the veneer veneer to the next process in a targeted manner (and safely to the next process). Conventionally, this manual method requires stopping, manually stretching, and then feeding to the next process. It is possible to completely eliminate aZ and improve the working rate.

[Brief explanation of the drawing]

Fig. 1 is an embodiment of the device of the present invention ff: a side view of the boss;
The figure is a plan view, and FIG. 3 is a broken view taken along the line A--A in FIG. 1. 5...Lower belt conveyor, 7...Suction duct, 13...Upper belt conveyor, 14...Touch l-1-ru, 15...Upper touch roll.

Claims (1)

[Claims] A suction duct is constructed opposite to the back side of the belt of the lower stage belt conveyor, which has a plurality of intake holes distributed over its entire length, and is further installed at an appropriate position above the first stage belt conveyor at a speed higher than the speed of the lower stage belt conveyor. A curl correction suction conveyance device for veneer veneer, characterized in that an upper stage belt conveyor that rotates quickly and in the same direction and can be raised and lowered is arranged in a row, and that rotation is stopped when the upper stage belt conveyor is raised.
