    METHOD FOR MOVING LONG-TERM WOOD
    FOR THE MANUFACTURE OF THE FEED ROLL AND THE FEED ROLL
    The invention relates to a method for producing a feed roll for moving elongated wood as defined in the preamble of claim 1 and to a feed roll as set out in the preamble of claim 8.
    The method according to the invention as well as the feed roller for the longitudinal movement of wood prepared in accordance therewith, the solution according to the invention, is very well suited for use in, for example, logging, where vertical trees are cut, pruned and chopped. The solution 15 according to the invention is suitable for use in moving the elongated timber in the longitudinal direction of the wood also outside of the harvest, for example in sawmill or planer plants or in other places where the long timber is moved in the longitudinal direction of the timber.
    In the treatment of elongated timber, and particularly in connection with harvesting, a feeder roller at the harvester end is used to move the truncated timber frame by rotating the feeder rolls in the longitudinal direction of the frame. When moving the trunk, the felled tree is also pruned and the trunk is moved to the desired cut-off point. The trunk is moved, pruned and cut off at the harvester head as many times as its length allows. In order for the above-mentioned trunk treatment to be effective enough, the feed rollers must be able to provide a sufficiently firm grip on the trunks of all sizes of the treated tree and allow a high enough transfer power even when pruning the branches. In addition, the feed rollers are exposed to the surface of the tree trunk
    20185050 prh 18-01-2018 The gripping elements must be shaped and constructed in such a way that the feed roller provides good grip and grip to move the wood so that the actual wood is not or only slightly damaged 5 and does not stick to the bark.
    One prior art solution is disclosed in United States Patent Publication No. US2010313997 A1. In it, the feed rollers comprise a tumbler body, the outer surface of which has fixed gripping teeth to provide sufficient adhesion to the movable wood frame. The problem with this solution is, among other things, that during the gripping teeth or damage to stones, for example, they are slow and difficult to repair.
    Another prior art feed roller for moving wood lengthwise is disclosed in European Patent No. EP2838343 B1. In it, the feed roller consists of parallel steel discs, the outer peripheries of which are provided with a serrated grip on the wood frame. The concentric gearwheels are connected to one another by spacers. The feed roller according to this solution has very high hard and therefore expensive metal parts that have to be machined very precisely, making the feed roll difficult and expensive to manufacture. In addition, when the teeth are damaged, for example by stones or other causes, at least one complete tooth disc must be replaced, or in some cases more, if the teeth of the parallel discs have been damaged to date. A further disadvantage of this solution is that the wood bark material easily passes into the open spaces of the parallel tooth disks, whereby the entire feed roller becomes clogged. In order to prevent clogging, a special cleaning comb is needed to remove the scrub material between the tooth disks.
    The object of the present invention is to eliminate the above drawbacks and to provide an inexpensive and simple method by which the feed roller for moving the elongated wood 5 can be manufactured easily and quickly. It is a further object of the invention to provide an inexpensive, simple construction, well-functioning and durable feed roller for moving elongated wood, which is also easily and quickly repaired after the vault. The method according to the invention is characterized in what is stated in the characterizing part of claim 1. Correspondingly, the feed roller according to the invention is characterized in what is stated in the characterizing part of claim 8. Other embodiments of the invention are characterized by what is stated in the other claims.
    20185050 prh 18-01-2018
    To accomplish the aforementioned purpose, the solution of the invention is directed to making a feed roll for moving elongated wood 20, the feed roll having a body to which the gripping members are attached to grip the movable wood. Preferably, the feed roll body is a substantially circular, or disk-like, body flange, on the periphery of which is located a plurality of sensing blade blocks that are locked in the radial direction of the body flange. Preferably, the blade pieces are locked immobile in the radial direction of the body flange by means of counter surfaces on the blade pieces.
    The solution of the invention also relates to a feed roller for moving an elongated tree, wherein the feed roller has a frame to which the gripping members are attached to grip the movable wood. Preferably, the feed roller body is provided with a substantially circular or disk-shaped body flange having peripheral blade discs acting as engaging means, which are locked in motion in the radial direction of the body flange. Preferably, the blade pieces are locked immobile in the radial direction of the body flange by means of mating surfaces in the blade pieces.
    An advantage of the solution according to the invention is, among other things, that the easily removable and replaceable blade pieces make it easy and quick to replace damaged and worn blade pieces, without the need for special tools or larger arrangements. This eliminates the need to completely replace the expensive feed roller if only one piece of blade is damaged.
    20185050 prh 18-01-2018
    A further advantage is that, for different purposes, such as different types of wood, it is easy to fit different blade pieces in the feed roller body which are best suited to the particular application. It also has the advantage that the blade attachment solution eliminates the need for welding in the feed roller. The solution according to the invention 20 allows the use of a plurality of blade pieces, which in turn allows a very good traction ability to move the movable wood. Another advantage is that, due to the design of the cutter blade, the amount of blade penetration into the wood is less than with prior art solutions. This also improves the yield of sawing and turning from wood compared to the prior art. It is also an advantage that the solution according to the invention allows lower compression pressures on the feed roller because the pulling capacity is so good. In this case, the feed rollers have a longer lifetime and a lower susceptibility to failure. Similarly, the fuel consumption of the machine will be reduced. Another advantage is that expensive and hard material only needs to be used in blade cuts. The other structure of the feed roller may be cheaper and softer material. In addition, the risk of boiling of the feed roller blocker is lower than many prior art solutions.
    The invention will now be described in more detail with the aid of 5 characters in your application with reference to the accompanying simplified drawings, in which:
    20185050 prh 18-01-2018 Figure 1 is an exploded top and side view of a feed roll of the invention, Figure 2 is an exploded top and side view of the feed roll of Figure 1, and Figure 3 is a side view of one of the feed rolls of the invention.

    Figures 1 and 2 show one of the feed rollers according to the invention, obliquely viewed from above and from the side. In Figure 1, the feed roller is assembled and in Figure 2, the feed roller is shown in an exploded pattern. The feed roll consists of a substantially disk-like body flange 1 and a plurality of detachable blade pieces 4 and detent elements 5, 7 disposed on the periphery of the body flange 1.
    Preferably, the blade pieces 4 are disposed radially and substantially evenly spaced around the periphery of the body flange 1. The blade pieces 4 are not permanently attached to the frame flange 1, for example by welding, but are easily removable and replaceable, if necessary by means of a form lock, so that the fixing of the blade pieces 4 to the frame flange 1 is also quick and easy. The fastening of the blade pieces 4 is secured by the fastening elements 5 and 7 which enable the shape to be locked, and by the fastening elements 6, such as bolts with threads. Preferably, the fastening elements 5 and 7 are, for example, substantially annular flanges, hereinafter referred to mainly as a side flange. The side flanges 5 and 7 are disposed centrally with the frame flange 1.
    Fig. 3 is a side elevational view of one design solution for use in the feed roller according to the invention and retaining the feed roller for both side flanges 5 and 7, but the other side flange 7 is preferably thicker than the first side flange 5; is provided with threads, whereas the holes 8 for fastening members 6 of the first side flange 5 have no threads. The threads of the second side flange 7 fit the threads of the fastening members 6. The side flanges and 7 are annular, round flanges, the outer periphery of which is preferably substantially flat and of smaller diameter than the outer periphery of the body flange 1, and whose inner periphery 5 has recesses 9 radially extending from the inner surface to the outer periphery 9 radially towards the periphery of the frame flange 1.
    Figure 4 shows another preferred design of the side flange 5 for use in the feed roller according to the invention. In this case, the side flange corresponding to the side flange 5, 7 of Fig. 3 is divided into four similarly circular arcuate portions which, when fixed together with the feed roller, form an annular side flange 5, 7 similar to the side flange shown in Fig. 3. The advantage now is that, if one or more of the successive blade pieces 4 is damaged, their replacement 20 is faster since not all the fastening means 6 need to be opened to effect the replacement of the blade pieces 4. Only that part or parts of the side flanges 5, 7 must be opened where the blade piece 4 has been damaged. The circular arc-shaped portions may preferably comprise two, three or even more than four instead of four.

    Fig. 5 is a side elevation view of a frame flange 1 for use in a feed roller according to the invention with one blade 4 used in the solution according to the invention. The frame flange 1 is preferably a round, substantially flat flange with a center bore 2 the recesses 11 extend through the thickness of the frame flange 1 and are substantially identical to one another and are disposed radially and
    20185050 prh 18-01-2018 at substantially even intervals with each other. The recesses 11 preferably have two parallel sidewalls 11b and a bottom acting as a counter surface 11a, which is closer to the center of the frame flange 1 than the outer periphery of the frame flange 1, into which the recesses 11 open. In the assembled feed roll, one cutter blade 4 is disposed in each recess 11 such that part of the blade piece 4 extends beyond the outer periphery of the frame flange 1 and part of the blade piece 4 extends inside the outer periphery of the body flange 1. The blade pieces 4 thus secured are arranged 10 to form the outer periphery of the assembled feed roll.
    The frame flange 1 further has a plurality of through holes 10 for the fastening members 6. The through holes 10 are spaced at equal intervals and at the same distance from the center of the flange 1. In addition, the through holes 10 are arranged such that the insert 4 in the recess 11 is always centrally located between the two through holes 10. The frame flange 1 further has a plurality of mounting holes 3 for securing the feed roller to a working machine or the like, and, if necessary, a plurality of other holes.
    Fig. 6 is a sectional view A-A of Fig. 5 showing one blade piece 4 used in the solution according to the invention, in position. For the sake of clarity, part 6 of Fig. 25 does not show the cutting pieces behind the cut blade piece 4 in the cut. The blade piece 4 has a substantially sharp tip portion 4a designed to obtain the best possible grip on the movable wood. Further, the blade piece 4 has one or more recesses 4b, preferably two recesses, the bottom of which is wider than the tip portion 4a and is intended to stop on the wood surface, so that the blade piece 4 does not sink too deep into the wood. The tip portion 4a of the blade piece 4 preferably has a width of the entire feed roll and thus forms the entire width of the feed roll. The blade piece 4 is locked in place in the recess 11 of the frame flange 1 by two side flanges 5 and 7 arranged to press the blade piece 4 from the side by means of fastening means 6, such as fastening screws. Further, the blade piece 4 has mating surfaces 4e and 4f arranged to rest on the inner surface mating surface 9a of the side flanges 5 and 7 so that the blade pieces 4 cannot move in the radial direction of the body flange 1.
    In Figures 7-9, the structure of the blade piece 4 is explained in more detail by means of three different blade pieces 4. In Figures 10 and 7, the blade pieces 4 are otherwise similar, but the recesses 4b of the tip part 4a are at a different position in the lateral, i.e. widthwise, direction of the blade piece 4 than the one shown in Figure 8.
    20185050 prh 18-01-2018
    Instead, the blade piece 4 of Figure 9 differs in that its tip portion 4a has no separate recesses, but the entire tip portion 4a is concave in the width direction of the blade piece 4 so that the concave portion of the tip portion 4a conforms to an outer surface of substantially circular cross section. Thus, the pressure of the blade piece 4 against the wood surface is more even and at the same time the grip, i.e. the traction, is improved. Instead of said recesses 4b, each side of the pointed tip has a counter surface 4h substantially perpendicular to the clamping direction of the cutting insert 4, which serves to prevent the sharp tip of the cutting insert 4 from sinking too deep into the wood. In this way, the mating surfaces 4h are arranged to stop the penetration of the pointed end of the tip portion 4a into the wood. Preferably, the mating surfaces 4h are concave in the same way as the entire tip part 4. However, the lower part, i.e. the foot 30, of the blade piece 4 of Fig. 9 is similar to the lower part of the blade pieces 4 of Figs.
    The thickness of the blade piece 4 corresponds to the width of the recess 11 on the outer periphery of the body flange 1, so that the blade piece 4 can be accommodated substantially free of recess 11. The lower part of the blade blade 4 has a substantially rectangular first rec The second edge of the first recess 4c, i.e. the edge further away from the tip portion 4a of the blade 5, has a mating surface 4e adapted to rest against the inner surface of the first peripheral flange 5 and a second edge 4d further from the edge 4a of the sold to rest against a counter surface 9a of the inner periphery of the second side flange 7. The mating surfaces 4e and 4f are arranged to prevent the blade piece 4 from falling out of position.
    20185050 prh 18-01-2018
    Between recesses 4c and 4d, the blade piece 4 has a slot-like recess 4g which opens away from the tip portion 4a of the blade piece 4, i.e. in the blade piece 4 stationary in the body flange 1 in the direction of the center of the body flange 1. The width of the recess 4g corresponds to the thickness of the frame flange 1 so that the blade piece 4 can be fitted substantially substantially free of the flange 11 of the frame flange 1 and further partially over the frame flange 1 between the center of the recess 11 and the frame flange. Hereby, the slot-like recess 4g of the blade piece 4 located in the frame flange 1 extends in the radial direction of the frame flange 1 as an extension of the slot-like recess 11 of the frame flange 1 towards the center of the frame flange 1. The resulting double-chlorine structure allows for a very rigid and robust feed roller structure, where welding is not required to assemble the parts, for example the blade pieces 4 are quick and easy to replace.
    The feed roller of Figs. 10-13 and its parts differ in structure from the foregoing only in that the feed roller now has only one side flange 5 and the threads of the fastening members 6 are in the holes 10 of the flange 1. similar to the above. Instead, the body flange 1 and the blade pieces 4 differ in their structure from the above.
    The blade piece 4 now does not have the above-described slot-like recess 4g, but the blade piece 4 is disposed on the body flange 1 from the side, whereby the blade piece 4 has only a recess 4c with the abutment surface 4e for the side flange 5 and now a recess 4d. Further, the blade piece 4 has a longitudinal projection 4i of the blade piece for insertion through the body flange 1, having a counter surface 4j corresponding to the abovementioned counter surface 4f to prevent the blade body 4 from moving in the radial direction of the body flange. The tip portion 4a of the blade piece 4 may be in the shape of Figs. 7-9 or in any other suitable shape.
    20185050 prh 18-01-2018
    Fig. 12 shows a side flange 1 used in the feed roller of Fig. 10 with one blade piece 4 attached thereto. The body flange 1 is otherwise substantially similar to the body flange 1 shown in Fig. 5, but now the holes 10 are threaded holes for fastening members 6 and on the inside of the periphery there is substantially an inner periphery formed, for example, by rectangular apertures 13, in which the apertures 13 are in the radial direction of the housing flange 1 substantially at the recesses 11. The peripheral wall of the housing flange 1 of the opening 13 has a mating surface 13a arranged to prevent the blade piece 4 from moving in the direction of the outer periphery of the housing flange 1.
    The size of the apertures 13 and the distance from the bottom of the recesses 11 are selected such that the cutter blade 4 can be pushed from the side of the housing flange 1 to the recess 11 while the projection 4i is positioned in the opening 13 and partially through the housing flange 1 to the other side.
    Fig. 13 is a sectional view E-E of Fig. 12 showing one piece of blade 4 for use in the feed roller of Fig. 10, fixed in place. For the sake of clarity, the cutter blades behind the cut blade piece 4 are not shown in section 13.
    The feed roller and its parts according to Figures 14-17 have a structure substantially similar to that shown above. Thus, the feed roller of Figs. 14-17 and its parts differ in structure from the above only in that the shape of the frame flange 1 and the blade piece 4 is partially different from that shown above.
    20185050 prh 18-01-2018
    In the solution of Figures 14-17, the feed roller has only one side flange 7 which acts as a fastening flange, the holes 8 having threads for the fastening means 6. The side flange 7 with its holes 8 and the recesses 9 and the fastening members 6 may be exactly the same as described above.
    Fig. 15 shows the body flange 1 for use in the feed roller of Fig. 14, obliquely viewed from above and in side with one blade piece 4. The body flange 1 is otherwise substantially similar to the body flange 1 shown in Fig. 5 25 but now the radial recesses 11 of but the groove depth of recess 11 from the first side surface of the frame flange 1 towards the second side surface of the frame flange 1 extends only to a part of the thickness of the frame flange 1.
    Preferably, the groove depth of the recess 11 is, for example, about half the thickness of the frame flange 1, wherein the bottom pleasure of the recess 11 is substantially in the center line of the thickness of the frame flange 1. The recesses 11 have two, preferably parallel, side walls 11b which act as a counter surface for the blade piece 4 and thus prevent the blade piece 4 from tilting away from its radial line to the body flange 1.
    In the assembled feed roll, a single cutter blade 4 is disposed in each recess 11 such that the blade blade 4 extends from the inside of the outer periphery of the frame flange 1 to the outside of the outer periphery of the frame flange 1. The blade pieces thus secured are arranged 4 to form the outer periphery of the assembled feed roll.
    Fig. 16 is a front view of one of the blade pieces 4 used in the feed roller of Fig. 14. The blade piece 4 does not have the above-described slotted recess 4g, but instead of the recess the blade piece 4 has a counter wall 4m arranged to match Further, the blade piece 4 has a recess 4d of the same kind as mentioned above, with a counter surface 4f for a side flange 7 with threaded holes 8. The mating surface 4f is arranged to rest on the mating surface 9a of the bottom of the recess 9 of the side flange 7 and thereby prevent the te 20 blade 4 from moving radially of the body flange 1 towards the periphery of the body flange 1. The tip portion 4a of the blade piece 4 may be in the shape of Figures 7-9 or in any other suitable shape.
    20185050 prh 18-01-2018
    Figure 17 shows one piece of blade 4 for use in the feed roller of Figure 14, fixed in position and cut from the center, as shown in Figure 12. For the sake of clarity, Fig. 17 does not show the cutting pieces behind the cut blade piece 4 in cutting.
    Each of the blade pieces 4 according to the invention also substantially has a mating surface 4k adapted to rest on a mating surface 11a on the bottom of the recess 11 in the body flange 1, or on the outer peripheral surface of the body flange 1, such as the feed roller. When supported, the counter surface 4k prevents the blade piece 4 from moving in the radial direction of the body flange towards the center of the body flange 1 by means of a locking mechanism. In addition, the side walls 11b of the recess 11 prevent the blade piece 4 from tilting away from its radial line radius.
    20185050 prh 18-01-2018
    The feed roll is preferably manufactured and assembled by the method according to the invention, for example as follows: sideways to the frame flange recess 11. The blade pieces 4 with slot-like recess 4g according to Figs. extending in the direction of the center of the frame flange 1. Hereby, the blade pieces 4 can be inserted deeper into the frame flange 1, but still so that the tip portions 4a of the blade pieces 4 extend beyond the outer periphery of the frame flange 1.
    Correspondingly, the blade pieces 4 with the recesses 4c and 4d of Fig. 11 are inserted into the recesses 11 of the frame flange 1 substantially laterally with the frame flange 1 being pushed from the side of the frame flange 1 to the recess 11 30 .
    The blade pieces 4 according to Fig. 16 are placed in the recesses 11 of the frame flange 1 substantially in the direction of the radius 35 of the frame flange 1 or on the side of the frame flange 1 so that the blade pieces
    20185050 prh 18-01-2018 The counterparts 4m rest on the bottoms of the recesses 11 in the thickness direction of the frame flange 1 and the blade pieces 4 are aligned with the recesses 11 and extend in the direction of the outer circumference of the frame flange 1.
    When the blade pieces 4 are disposed in the frame flange 1, they are preferably secured by means of a shape lock. Hereby, at least one side flange 5 and / or 7 is secured to the flange 1 by means of fastening members 6 to press the blade 10 against the foot flange 1 of the piece 4 and form a counter surface 9a on the counter surfaces 4e, 4f.
    1, two side flanges 5 and 7 are used for shape locking, which are disposed on opposite sides of the body flange 1 in recesses 4c and 4d in the blade pieces 4 so that the counter faces 4e and 4f in the recesses 4c, 4d 4 cannot move in the radial direction of the frame flange 1 outwardly from the frame flange 1. Preferably, the mating surfaces 4e and 4f of the blade piece 4 rest on the mating surfaces 9a of the bottoms 9 of the inner periphery of the recesses 9 of the flanges 5 and 7.
    10, one side flange 5 and openings 13 in the frame flange 1 are used to support the shape reading25. The side flange 5 is inserted from the side of the blade pieces 4 into the first recesses 4c in the blade pieces 4 so that the counter surfaces 4e move in the radial direction of the frame flange 1 outwards from the frame flange 1. Preferably, the abutment faces 4e of the blade pieces 4 rest on the abutment faces 9a of the bottoms 9 of the inner periphery of the side flange 5. While the blade piece 4 is pushed laterally into the recess 11 of the body flange 1, the projection 4i in the lower part 35 of the blade piece is inserted into the opening 13 of the body flange 1 so that
    20185050 prh 18-01-2018 far so that one side wall of the frame flange 1 contacts the bottom of the second recess 4d of the blade flange 4. The abutment surface 4j in the projection 4i rests on the abutment face 13a of the body flange 1 of the aperture 13 so that rubber movement of the blade piece 4 in the radial direction of the abutment flange 1 is prevented.
    In the feed roll of Fig. 14, one side flange 7 with threaded holes 8 is provided for shape locking and is disposed on one side of the housing flange 1 in recesses 4d 1 radially outwards from the housing flange 1. Preferably, the abutment faces 4f of the blade piece 4 rest on the abutment faces 9a of the bottom of the recesses 9 of the inner flanges of the side flanges.
    The final fastening of the blade pieces 4 is secured by fastening means 6, such as fastening screws, by which the side flanges 20 5 and 7 or only one side flange 5 or 7 are pressed against the frame flange 1. When all the fastening members 6 are secured in place, the feed roller is pre-assembled.
    If the blade pieces 4 need to be replaced due to damage or wear, remove the fastening elements 6 and the side flanges 5 and / or 7 used for attachment, and then the replaceable blade pieces 4. Replace the removed blade pieces 4, then use the lateral flanges 5 and / or 7 tighten back to the ground flange 1 in place.
    In one preferred embodiment, the side flanges 5, 7 or the feed roller of Figure 10 consist of more than one part of the side flange 5 as shown in Figure 4.
    Thus, when replacing the blade pieces 4, only that part or parts of the side flanges 5, 7 which need to be removed in order to replace the blade pieces 4 are removed, preferably, for example, only one or two parts.
    It will be apparent to one skilled in the art that various embodiments of the invention are not limited to the examples above, but may vary within the scope of the following claims. It is essential that assembly of the feed roller does not require welding and that the te10 blades are easily and quickly replaceable when needed.
    It will also be apparent to one skilled in the art that instead of one or four side flanges 15 shown in Figure 4, the side flanges may also consist of two halves of a circular ring, three parts, or even more than four parts.
    It will also be clear to one skilled in the art that the fastening means for clamping the side flanges towards the frame flange may also comprise nuts, so that there is no need to thread the holes in the fastening means on the other side flange or frame flange.
    20185050 prh 18-01-2018
    It will also be apparent to one skilled in the art that the shape of the tip portion of the blade pieces may be curved as shown in Fig. 9, even when the tip of the blade piece has recesses according to Figures 7, 8 and 16 or other recesses or elevations.
    It is also obvious to a person skilled in the art that the inner periphery of the side flanges acting as fastening elements may also be uniform in place of the serrated or grooved inner periphery. Thus, the substantially smooth inner periphery preferably has only one continuous counter surface, which may be the entire inner periphery. If the side flange consists of several parts, for example, as shown in Fig. 4, said mating surface preferably has a smooth inner peripheral arc of each part.
    It will also be obvious to a person skilled in the art that the blade pieces need not necessarily have all of the abovementioned counter surfaces for locking the blade pieces in motion in the radial direction of the body flange. Hereby, the blade pieces are locked in motion by one or more side flanges acting as a fastening element in the radial direction of the body flange, whereby the pressing of the side flange towards the body flange keeps the blade pieces immobile by friction.
