Description
:L
Apparatus for feeding side boards in a sawmill The present invention relates to an apparatus for feeding side boards in a sawmil.l immediately after a log or a block has been sawn into a central portion and side boards, comprising a longitudinal conveyor for transport of the central portion in longitudinal direction, movable supporting planes supplied on both sides of the longitudinal conveyors for temporarily holding up the side boards, and side supports for supporting the side boards in side direction.
An object of the invention is to make possible automation of the treatment of side boards and to provide an apparatus for feeding side boards from which the side boards are after sawing receivecl separetely the cant edge upwards for further treatment, e.g. trimming, when at least two si.de boards are sawn from both sides of a log or a block.
The Swedish published patent application no. 415864 di.scloses an apparatus, where the side boards are dropped one by one onto a conveyor formed by pockets or the like but the apparatus is complex and due to many phases of operation slow.
The capacity of the apparatus according to the invention corresponds to the output capasit~ of the present fas-t sawing and trlr~ming machines. The apparatus according to the invention is mainly characterized by the fact that slopes are disposed beneath a longitudinal conveyor on both sides of it along which the side boards slide down onto a transverse conveyor, and that the slopes are provided with stopping means to stop the inner side boards while the outer ones continue their travel towards the transverse conveyor.
The invention is described in detail with reEerence to the attached drawings, including figures 1 to 3, which illustrate in schematic representation the consecutive operation phases OI
a feedincJ appartus according to the invention.
~` 1 Tn the figures the numeral 1 refers to a conveyor and the numerals 2 and 3 to supporting planes disposed pivotably on both sides of the conveyor. Further, the apparatus comprises support rollers 4, 5 on both sides of the conveyor. Beneath the conveyor on both side of it there are slopes 6, 7 and in the slopes movable stopping means 8, 9. Flexible guides 10, 11 are disposed beside the slopes between the supporting planes and the stopping means.
In figure 1 the central portion 16 of a sawn log is transferred in its longitudinal direction on the conveyor 1 while the side boards 17, 18, 19, 20 rest on the supporting planes 2, 3.
Support rollers 4, 5 support the side boards in the side direction.
When a 1og has been sawn the side boards are released from the pressure of the support rollers 4, 5 and the supporting planes

The invention is described in detail with reEerence to the attached drawings, including figures 1 to 3, which illustrate in schematic representation the consecutive operation phases OI

~` 1 Tn the figures the numeral 1 refers to a conveyor and the numerals 2 and 3 to supporting planes disposed pivotably on both sides of the conveyor. Further, the apparatus comprises support rollers 4, 5 on both sides of the conveyor. Beneath the conveyor on both side of it there are slopes 6, 7 and in the slopes movable stopping means 8, 9. Flexible guides 10, 11 are disposed beside the slopes between the supporting planes and the stopping means.
In figure 1 the central portion 16 of a sawn log is transferred in its longitudinal direction on the conveyor 1 while the side boards 17, 18, 19, 20 rest on the supporting planes 2, 3.
Support rollers 4, 5 support the side boards in the side direction.
When a 1og has been sawn the side boards are released from the pressure of the support rollers 4, 5 and the supporting planes
2, 3 are wound down as is illustrated in figure 2, whereby the side boar~s dropp down into converging spaces 21, 22 formed by the slopes 6, 7 and the guides 10, 11. The stopping means ~8 r 9~, the tips of which project t:hrought the slide surfaces as is illustrated in the figure, stop the side boards 19, 20 which are after sawing closer to the central portion. The outer side boards 17, 1~ continue without stopping their travel towards the transverse conveyors 12, 13 further down. The slopes are thus formed that the side boards dropp down onto the transverse conveyor the cant edge up whereby they need not be turned before trimming. The position of the side boards on the transverse conveyor is corrected by pins 14, 15.
After this the pins 14, 15 are lowered down and the side boards 17, 18 are transported away, whereby the conveyors are ready to accept the outer side boards 19, 20~ The stopping means 8, 9 are then turrled to their down position, as is :indicated in figure 3, whereby the side boards slide down alon~ the slopes and dropp onto -the transverse conveyor 12, 13. The supporting planes are returned to their lnitial. position and the apparatus is ready to accept the side boards of the next log.
The invention is applicable also when three side boards at a time are sawn from both sides of a central portion. Two stopping means can then be disposed in the slopes at a distance Erom each other in the direction of the travel of the side boards, whereby, after the supporting planes 2, 3 have dropped the side boards, the first stopping means arrest the innermost side board, the second one stops the side board in the middle and the outermost board conti.nues its travel without stopping towards the transverse conveyor.
The invention is not limited to the embodiments which are presented here as examples, only, but several modifications and variations can be made of it without deviating from the scope of the invention~
