Abstract
ABSTRACT OF THE DISCLOSURE
The invention provides an apparatus for feeding trees in their longitudinal direction into a processor along the treatment line. The apparatus may be used for lopping, measuring, spray-protecting, cutting, sorting, or any other corresponding operation. The apparatus comprises two feeding rolls or rollers provided with surfaces of sufficient adhesive capacity. The feeding rolls are arranged above and underneath the feeding line of the trees and are mounted on substantially horizontal axles each of them at an arm of its own. The arms are pivotable in the vertical direction and are fastened, by means of articulated joints, at a vertical distance from each other, to the frame of the treatment line. A cylinder-piston apparatus is arranged between the arms of the feeding rolls and produces the compression force required by the feeding rolls and guarantees continuous drive by both feeding rolls. The upper feeding roller is placed somewhat closer to the beginning of the treatment line than the lower feeding roller.

Description
~4~
The subject of the present invention is an app~ratus for feeding trees along the treatment line of a processor for the purpose of lopping and/or measuring and/ox Spray-protecting and/or cutting and/or sorting the trunk and/or for any other corresponding operationr the aPParatus for feeding the trees comprising two feeding rolls or rollers provided with surfaces of sufficient adhesive capacity and said feeding rolls being arranged above and underneath the feeding line of the trees and being mounted on substantially horizontal axles each of them at an arm of its own, which arms are pivotable in the vertical direction and fastened, by means of articulated joints, at a vertical distance from each other, to the frame of the treatment line. .
The feeding apparatus in accordance with the present invention is mainly characterized in that a cylinder-piston apparatus is arranged between the arms of the feeding rolls, which apparatus produces the compression force required by the feeding rolls and guarantees continuous drive by both feeding rollers, and that the upper feeding roller is placed somewhat closer to the beginning of the treatment line than the lower feed roller.
The invention comes out more closely from the .
following description and from the attached drawings, wherein:
FIGURE 1 shows the prOCeSSQr as a side view;
FIGURE ~ shows the processor of Figure l as a : ~`
front view; ~ .FIGURES 3 and 4 schematically show the feeding of :
a tree trunk by means of the Eeeding rollers :
as a side view, and FIGURE 5 shows the pair of drive rollers as viewed from the direction of feeding.
,. ~ .
~49~
Figures l and 2 show the feeding apparatus 2 in accordance with the present invention as arranged to the beginning of the treatment line 1 of a processor.
The feeding apparatus consists of two rollers 3 and 4 rotating around substantially horizontal axles and provided with surfaces of sufficient adhesive capacity, the rotating momentum of which rollers required for feeding the tree 8 is ohtained, for example, from hydraulic motors placed in the rollers, as well as of two arms~5 and 6, which are, by means of articulated joints, fastened to the same object 9, a working cylinder 7 mounted between said arms producing the required compression force on the rollers 3 and 4.
The arms S and 6 are mounted in the line 1 for the treatment of trees on shafts 10 and 11, which are trans~
versal to the direction of movement of the tree and placed in the same plane as the axles of the rollers. This articulated mounting permi~s the lower roller 4 to grasp the tree even if the trunk 8 were highly curved or had a large root expansion, as is shown in Figure 4. In this way, continuous drive is guaranteed from both rollers 3 and 4. ~;~
Due to the longer arm 5 of the upper roller 3, one support point of the trunk 8 is almost always a lopping means, because of which the lopping means 13 and 14 are always able to come as close to the surface of the trunk 8 as possible. Moreover, due to the difference in length of the ~rms 5 and 6, it is possible.to use rollers of the shape of a double cone so that, due to overlapping of the rollers 3 and 4, the diameter dimension remaining between them can be made sufficiently small (Figure 5).
~48~7 The upper roller 3, with the lon~er arm-5, is better able to grasp the root ends of the trees ~s well which, due to thelr length or the inclination of the ground, form a rather large angle with the plane of treatment of the line 1.
In the case shown in Figures 3 and 4, the cylinder-piston apparatus 7 arranged between the.arms 5 and 6 is placed between the rollers 3 and 4 and the articulation points 10 and 11, but it can of course also be. placed between extensions of the arms S and 6 passing beyond the articulation points 10 and 11.
The invention is not restricted to the exemplifying embodiment described above alone, but it may show variation in many ways within the scope of the patent claims.
