Abstract
A take-up reel has a diameter equal to or more than 85 times a thickness of a veneer sheet wound thereon and equal to or more than 300 mm so as to be of a curvature of the take-up reel to reduce cracking in parallel to fiber orientations that occurs in winding a veneer sheet after drying on a winding surface of the take-up reel. A
veneer reeling apparatus comprises: a take-up reel disposed in a veneer sheet reeling position in a rotatable manner; a drive roller disposed on the lower surface of the take-up reel, transmitting a driving force with a variable speed; a veneer dryer disposed upstream from the veneer sheet reeling position; a conveyor provided between the terminal end of the veneer dryer and the drive roller in the veneer sheet reeling position;
and a plurality of thread feeding mechanisms disposed at arbitrary spatial intervals along a length direction of the take-up reel for a veneer sheet, wherein a continuous dried veneer sheet or dried veneer sheets whose sizes are of a constant length or of a length at random are wound on the take-up reel to form a veneer roll with threads as guide by a frictional force of the drive roller. Further, pairs of two overlapping veneer sheets or sets of a pair of two overlapping veneer sheets and a single veneer sheet can be wound on the take-up reel in a composite form.

Claims (8)
1. A veneer reeling apparatus at least comprising:
a take-up reel that is rotatably supported at a veneer sheet winding position;
a winding guide member arranged in an opposite manner to the circumferential surface of the take-up reel in plural rows with arbitrary spatial intervals along a shaft direction of the take-up reel;
rotation transmitting means that imparts rotation to the guide member in order to wind a veneer sheet on the take-up reel;
following means that forces the winding guide member to run along part of the circumferential surface of the take-up reel in conformity with the curvature of thereof;
a transport conveyor that transports a veneer sheet into between the take-up reel and the winding guide member in cooperation with the winding guide member below the take-up reel; and firmly stretching means that imparts a tension to the winding guide member in order to wind a veneer sheet car the take-up reel in transportation.
a take-up reel that is rotatably supported at a veneer sheet winding position;
a winding guide member arranged in an opposite manner to the circumferential surface of the take-up reel in plural rows with arbitrary spatial intervals along a shaft direction of the take-up reel;
rotation transmitting means that imparts rotation to the guide member in order to wind a veneer sheet on the take-up reel;
following means that forces the winding guide member to run along part of the circumferential surface of the take-up reel in conformity with the curvature of thereof;

2. A veneer reeling apparatus comprising: a connection conveyor that is provided with a pulse generator; a detector that senses a veneer sheet after drying transported on the connection conveyor; a distance setter that sets a distance from the detector to a winding guide member that is located downstream from the detector; a drive controller that controls driving of the winding guide member;

and a take-up reel that is rotated following rotation of the winding guide member by being kept in contact with an upper surface of the drive roller, wherein when a veneer sheet in transportation on the connection conveyor is sensed, driving of the winding guide member is stopped in response to an instruction from the drive controller, and when a predetermined number of pulses corresponding to a set distance is counted up, the winding guide member is driven to wind a veneer sheet on the take-up reel.
3. A veneer reeling apparatus according to claim 1 or 2 comprising a plurality of thread feeding mechanisms that feeds threads wound as guide in winding a veneer sheet on the take-up reel arranged in a shaft direction of the take-up reel.
4. A veneer reeling apparatus according to any of claims 1 to 3, wherein the winding guide members include endless bands extend over at least three positions in a base end section, a middle section and a distal end section, wherein the winding guide member is owed to a distal end of the transport conveyor and when the winding guide means is swung toward the take-up reel by the following means, the winding guide means is pressed on part of the circumferential surface of the take-up reel in conformity with a curvature of the part.
5. A veneer reeling apparatus according to any of claims 1 to 4, wherein the winding guide member includes endless bands; the base end thereof is located below a veneer sheet winding position and the distal end thereof is free; the winding guide member is connected to the distal end of the transport end; and when the distal end of the winding guide member is swung toward the take-up reel by the following means with the base end as a fulcrum, the winding guide member is pressed on part of the circumferential surface of the take-up reel in conformity with a curvature of the part.
6. A veneer reeling apparatus according to any of claims 1 to 5, wherein the firmly stretching means is rotary pulleys that are provided in order to push or pull the endless bands constituting the winding guide member under a pressure while guaranteeing a rotation force of the winding guide member when the winding guide member is pressed in conformity with the curvature of part of the circumferential surface of the take-up reel, wherein the firmly stretching means displaces a press position of the winding guide member on the take-up reel as a diameter of a veneer roll produced by winding a veneer sheet on the take-up reel increases while maintaining the winding guide her in a firmly stretching condition under a constant tension.
7. A veneer reeling apparatus according to any of claims 1 to 5, wherein the firmly stretching means is rotary pulleys that are separately provided in order to individually push or pull endless bands in plural rows constituting the winding guide member under a pressure while guaranteeing a rotation force of the winding guide member when the winding guide her is pressed in conformity with the curvature of part of the circumferential surface of the take-up reel, wherein try firmly stretching means can individually displace press positions of the endless bands on the take-up reel as a diameter of a veneer roll produced by winding a veneer sheet on the take-up reel increases while maintaining the winding guide member in a firmly stretching condition under a constant tension.
8. A production method for laminated wood in which a veneer sheet is reeled by means of a veneer reeling apparatus according to any of claims 1 to 7 in steps in which a veneer sheet is wound into a veneer roll and a veneer sheet is unwound from the veneer roll.
