Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for correcting a posture of a veneer veneer having a small width to be cut or cut and feeding the veneer veneer to these machines.

(Prior art) As a means for feeding a small width veneer to a sized clipper or a horizontal scribing machine with its posture corrected, the veneer is transported on a conveyor for transporting the veneer in a direction orthogonal to the fiber. Providing a pair of upper and lower endless belts or rollers that are driven inclining with the direction, or having an axis in the same direction as the transport direction and providing a roller with a spiral lead member on the surface, a veneer A method of correcting the posture by moving it in the lateral direction has been used.

(Problems to be Solved by the Invention) In the former case of the conventional method, it is necessary to drive an endless belt or a roller which is inclined with respect to the conveying direction of the veneer. It is difficult to match the speed and the feeding becomes unstable, and it is necessary to carry high pressure in order to obtain a reliable lateral feeding component. Since the lateral movement of the veneer is performed against strong frictional force, There are difficulties such as excessive wear and damage to the mouth of the veneer,
In the latter case, the contact with the veneer is intermittent because the spiral lead member is used, and the posture correction is uncertain.
In addition, there was a problem in that the lead member was significantly worn due to friction with the veneer.

(Means for Solving the Problems) A slide in which the insides of two endless belts at appropriate intervals are connected by a large number of connecting rods, and the connecting rods are provided with a large number of sliding conveyance pieces slidable in the length direction thereof. The moving endless transport belt is vertically opposed to form a holding transport path that mainly transports the veneer in a direction perpendicular to the fiber by the sliding transport piece, and the sliding transport piece of the upper and lower sliding endless transport belt is formed. Are provided in order to guide the vehicle sequentially in the lateral direction.

(Operation) The single-panel holding conveyance path is formed by the sliding conveyance pieces of the sliding type endless conveyance belt provided vertically, and the sliding conveyance pieces are sequentially moved laterally by the inclined guide member. In addition, the veneer can be stably transported in the feed direction, and the veneer can be laterally moved without applying a strong feed force to the veneer and without resisting the frictional force of the transport member.
