    The invention relates to a feed roller for a feed machine for feeding trees to a barking machine comprising a feed roller, fastening means for attaching the adhesive patches to the body.
    US 20080178965 A is known from the prior art, which discloses a feed roller for a peeling machine. By peeling machine is meant in this context a peeling machine connected to sawmills, which peels the trees one by one by means of a bark rotor. The aforementioned U.S. publication discloses a feed roller for a peeling machine comprising a cylindrical body and adhesive pads spaced therefrom. The feed roller is attached from its frame to the drive shaft of the drive motor of the peeling machine, which rotates the feed roller to move the wood through the peel rotor. The adhesive pads can be detachably attached to the frame.
    S 25 g The problem with the feed roller of the peeling machine according to the above-mentioned prior art is that the feed roller is closed = cylinder. When feeding trees, the bark comes off the surface of the wood, and in winter also snow when the sticky notes hit the surface of the wood. The shell, = 30 snow and other possible dirt end up between the gripping pads against the closed body of the 2 feed rollers, filling the gaps between the gripping pads N. Eventually, the surface of the material accumulating between the adhesive patches rises so high that the adhesive patches cannot get caught on the surface of the wood while the material trapped between the adhesive patches prevents the wood from moving closer to the feed roller body. In other words, the material between the adhesive patches begins to “carry” the wood, preventing the adhesive patches from sinking into the wood.
    The object of the invention is to provide a more reliable and lighter feed roller than the feed rollers of the prior art peeler. The characteristic features of the present invention appear from the appended claim 1. It is also an object of the invention to provide a peeling machine which is more reliable than prior art peeling machines. The characteristic features of the present invention appear from the appended claim 15. The object of the invention can be achieved with a peeling machine feed roller for feeding trees to a peeling machine comprising a frame comprising connecting means for connecting a feed roller to a peeling machine. , and attachment means for attaching the adhesive pads to the body. The body is a circular center disc in which recesses are formed in the direction of the radius of the center disc to attach the adhesive patches to the body in the direction transverse to the center disc. The recesses on the outer circuit of the middle disc are> 25 separated by the bases belonging to the middle disc. it The adhesive patches are fitted with a thickness substantially e with the length of the recesses parallel to the outer circumference of the central disc = equal to detachably fit the adhesive patches to the recesses substantially without backlash. The fastening means are = 30 wedges removably fastened to the bases, each of which 2 wedges are adapted to fasten at least one gripping tab N to the middle disc.
    In the feed roller of the peeling machine according to the invention, the body of the feed roller is substantially open, since the plate-like central disc forms a body which extends only a part of the distance from the entire width of the feed roller. Sufficient width of the feed roller is achieved by means of adhesive patches attached transversely to the frame. The distance between the gripping pads in the direction of rotation of the feed roller leaves a lot of free space between the gripping pads, through which the bark, snow and other material of the wood can escape between the gripping pads. The modular design of the feed roller also allows for easy maintenance and modification of the feed roller according to the needs of the application. Preferably, the wedges are tightened on the center disc in the radial direction of the center disc. In this way, the wedges can be between the gripping tabs supporting the gripping tabs to each other in the direction of rotation of the feed roller without backlash. Preferably, the gripping tabs are shaped so that the diameter of the feed roll increases away from the plane of the center disc to center the wood on the feed roll. In this way, the wood in contact with the feed roller drifts gravity into the center of the feed roller and is correctly oriented on the bark rotor of the peeling machine. In other words, the contact surface of the adhesive patches is in the shape of a wide V, so that the contact surface to the wood is> 25 larger than the direct contact surface, improving the operation of the feed roller.
    SO According to one embodiment, each contact surface of the adhesive patch includes teeth projecting from the contact surface, each having a long planar surface protruding from the contact surface = 30 and a short planar surface interlocking at an angle 2 2 to form a tooth tip closer to the center of the long tooth or a junction of a short planar surface to the contact surface to prevent rotation of the wood. The bark rotor blades, when peeling wood, produce a force that tends to rotate the wood.
    If the surface of the feed roller is slipped with bark, snow, or other contaminants, the wood may rotate on the feed roller, causing the peeling to fail.
    When the above-mentioned teeth are used, the teeth are directed towards the central disc, whereby they prevent the rotation of the wood when it is fed by a feed roller to the bark rotor.
    The segment formed at the intersection of the long planar surface and the short planar surface of each tooth, namely the tip, may be transverse to the plane of the gripping patch for gripping the tooth into the wood as it is fed as the feed roller rotates.
    This creates an edge between the tooth tip and the planar surface of the gripping patch which strikes the wood at an angle as the feed roller rotates and bites into the wood and its bark, whereby the feed roller effectively pushes the wood forward towards the bark rotor as the feed roller rotates.
    Preferably, each gripping tab includes a lower groove for locking the gripping tab to the frame in the transverse direction of the feed roller, the lower groove corresponding in width to the thickness of the central disc at the recess.
    By means of the lower slot, the gripping tab is locked in the width direction of the feed roller, the lower slot being form-locked in that direction with the central disc and its recess. Preferably, each gripping tab comprises an upper groove for said wedge, the wedge being adapted to press the gripping tab e from the upper groove towards the center disc to lock the gripping tab to the frame in the radial direction of the feed roller. The upper groove has the same width as the wedge width
    The upper slot can be used to improve the locking of the gripping tab 2 in the width direction of the feed roller, while the upper slot increases the stability of the N locking.
    The upper groove also ensures that the wedges remain below the contact surface of the adhesive patches,
    whereby the wedges do not under any circumstances carry the load of the wood, but the wood only touches the contact surfaces of the adhesive patches. According to one embodiment, the feed roller includes end support discs adapted to engage at least a portion of the gripping rods to improve the rigidity of the feed roller. The end support discs can be used to improve the support of the adhesive patches on the feed roller.
    The width of the central disc in the direction perpendicular to the plane of the central disc may be 10 to 40%, preferably 20 to 25% of the width of the feed roller and the adhesive pads. In this case, the body of the feed roll is sufficiently open to allow the bark, snow and other material of the wood to escape freely between the gripping rollers in the radial direction of the feed rollers inside the gripping rollers in and out of the feed roll.
    Preferably, the adhesive patches are planar pieces. The planar parts can be manufactured quickly and cost-effectively, for example by laser cutting, without welding.
    According to one embodiment, each gripping patch comprises o a central portion comprising a lower slot and an intermediate slot, and wing portions associated with the central portion> 25, each wing portion having a lower surface closer to the center disc and an upper surface respectively. perpendicular to the plane, i.e. to increase the diameter of the feed roller away from the plane of the center disc = 30. Such a gripping patch structure concentrates 2 trees in the center of the feed roller.
    N Preferably, each wedge is adapted to attach the gripping tabs in the nearest recesses on either side of the base to the center disc. This increases the safety of using the feed roller when each grip tab is locked with two wedges. In addition, the stresses on the wedge and the bolt used to lock it are symmetrical.
    The middle disc may comprise 16 to 40, preferably 24 to 32 recesses at regular intervals from each other, and a corresponding number of gripping patches and wedges. In this case, there are sufficiently large gaps between the adhesive patches in the feed roller, but the adhesive patches are close enough to each other to ensure continuous and firm contact of the feed roller with the wood. According to one embodiment, each wedge comprises a wedge-shaped body part adapted to be wedged between the gripping pads and at least one wing substantially parallel to the feed roller circuit adapted to press the gripping pad into said central disc recess. In other words, the vane is substantially parallel to the tangent of the feed roller. The wedge-shaped shape of the wedge causes that when the wedge is tightened towards the center disc, in addition to the radial force of the center disc, the wedges provide a tangential force to the gripping tabs to support them substantially through the wedges. Preferably, each center disc base includes a threaded bore and each wedge includes a center hole for securing the wedge e through the center hole to the center disc bore. Thus = each wedge can be fastened by means of a single bolt, so that fastening and removal is quick. > 30 5 According to one embodiment, every other gripping patch is N narrower in width to increase the free surface area of the feed roller. This increases the amount of free surface area of the feed roller.
    The middle disc is preferably a piece formed by milling a single piece. In this case, the strength of the part is very high. The center disc may include an inner flange portion having openings for attaching the center disc to the drive shaft of the peeling machine drive motor and an outer and wider foot portion relative to the flange portion having recesses formed for the adhesive pads. With such a structure, the middle disc can be quite light with its flange part being quite thin, but at the same time provide a sufficient torque support for the gripping tabs to be attached to the foot part by means of a wider foot part. The width of the central disc at its widest part may be 40 to 100 mm, preferably 50 to 70 mm. Preferably the wedge has a width of 25 to 55%, preferably 35 to 45% of the width of the recess. In this case, a triangular support is provided for each gripping patch, in which the support providing the recess for the gripping patch comes in a wider area than the wedge. When the wedge is narrow enough, the wedge will not support the wood at any point. Preferably, the gripping tabs are removably attachable to the body. This makes them easy to change. S 25 it The diameter of the feed roller can be 300 to 800 mm, preferably 400 to 600 mm. x a LO The width of the feed roller can be 200 to 500 mm, preferably 300 to 350 mm.
    The purpose of the peeling machine according to the invention can be achieved by a peeling machine for peeling trees, which includes feed rollers for feeding trees to the peeling machine one tree at a time,
    a bark rotor comprising bark blades for debarking wood as the wood moves through a longitudinally rotating bark rotor pushed by feed rollers, and a feed roller drive motor comprising a drive shaft to which each feed roller is connected.
    The feed roller includes a body comprising connecting means for connecting the feed roller to a drive shaft of a drive motor belonging to the peeling machine, gripping pads attached to the body, each gripping pad having a contact surface for gripping the feed roll to wood, and attaching means for attaching gripping pads to the body.
    The body is a circular center disc in which recesses are formed in the direction of the radius of the center disc to attach the adhesive patches to the body in the direction transverse to the center disc.
    The recesses are on the outer circuit of the center disc separated from the bases belonging to the center disc.
    The adhesive pads are arranged to be substantially equal in thickness with the length of the outer circumference of the central disc of the recesses in order to releasably fit the adhesive pads to the recesses substantially without backlash.
    The fastening means are wedges releasably fastened to the bases, each wedge being adapted to fasten at least one gripping tab to the central disc.
    Preferably, the drive shaft of the drive motor is attached to the feed roller on one side.
    This leaves> 25 more free space in the middle of the feed roller for the removal of shell, snow and contaminants. © = Preferably, the debarking machine comprises two feed rollers in the direction of travel of the wood before the bark rotor and two feed rollers = 30 after the bark rotor, which feed rollers before and after 2 bark rotors are arranged vertically one on top of the other and parallel to the parallel drive axes to feed the trees.

    o Figure 1 shows a prior art peeling machine> 25 100 comprising a body 112, a peel rotor g 108 attached thereto and prior art feed rollers 107. The peel rotor 108 comprises peel blades 110 with an opening in the center = through which is shown in broken lines. the wood 102 is fed into the bark through the rotor 108. The circumference 114 of the shell rotor 108 rotates, = 30 whereby the shell blades 110, which are preferably spring-loaded attached thereto, also rotate. The rotating movement N of the bark materials 110 removes the cross-section of the bark wood of the wood 102 in the tangential direction. In the prior art peeler 100, the feed rollers 10 'are suspended at the ends of the hydraulically loaded arms 116 by drive motors 104. There are three feed rollers 10 "and they form an opening for wood 102 between them.
    The basic structure of the peeling machine according to the invention may correspond to the peeling machine according to the prior art shown in the figure. The difference arises from the structure of the feed rollers. Preferably, the feed rollers also have two bark rotors on both sides and the feed rollers 10 are vertically superimposed as shown in Fig. 9, whereby the wood 102 is fed between them. In other words, before the bark rotor there is one pair of feed rollers for pushing the wood forward towards the bark rotor and after the bark rotor there is another pair of feed rollers for pulling the wood away from the bark rotor. For example, the feed rollers can be hydraulically loaded, so that the pressure they exert on the surface of the wood can be adjusted to prevent damage to the wood.
    Figures 2a to 2c show a preferred embodiment of the feed roller 10 according to the invention. The feed roller 10 according to the invention comprises a body 12 comprising connecting means 14 for connecting the feed roller 10 to the drive shaft 106 of the drive motor 104 of the peeling machine 100 shown in broken lines in Figure 2c, gripping tabs 16 attached to the body 12 and fastening means 20 for attaching the adhesive pads 16 is a modular structure in which its parts can be easily detached and attached to each other. © = The body 12 of the feed roller 10 is the central disc shown in Figures 3a to 3c 22. The central disc 22 may be machined by machining preferably one = 30 pieces of metal, preferably comprising 2 inner flange portions 66 including N openings 64 acting as connecting means 14 for attaching the central disc 22 to the peeling machine. - on the drive shaft of the traction motor by means of bolts and relative to the flange part 66 in the radial direction of the central disc 22, the outer and wider foot part 68,
    formed with recesses 24 for adhesive patches. The narrow flange portion 66 is intended to act as a mounting surface for the drive motor drive shaft flange, while the wider foot portion 68 provides a sufficiently wide support surface for the secure attachment of the gripping tabs. Preferably, the flange part has a thickness of 20 to 50 mm in the width direction of the feed roller, while the foot part has a thickness of 60 to 110 mm, preferably 70 to 90 mm. There may be an opening 75 in the center of the flange portion 66 to lighten the center disc 22. As shown in Fig. 3b, radially recesses 24 are formed in the foot portion 68 of the center disc 22. At the recess 24, the diameter of the center disc 22 is smaller by the depth of the recess 24. The width direction of the recesses 24 is parallel to the drive shaft of the drive motor. Each recess 24 is preferably a continuous slot throughout the width of the foot portion 68. The depth of the recess 24 in the radial direction of the central disc 22 may be 25 to 50 mm. The recesses 24 are separated from each other by means of bases 26 belonging to the sensor part 68 of the central disc 22. The length of the recess 24 in the direction of the tangent of the feed roller is preferably 25 to 40%, preferably 30 to 40% of the length of the base 26. Preferably, however, the length of the base is at least 35 mm so that there is sufficient space between the adhesive patches. In the middle of each base 26o there is preferably a bore 60 in which> 25 counter-threads are formed for the bolt. Outside the bore 60, the base 26 preferably includes chamfers 70 which tilt from the bore O towards the center of the central disc 22 in the transverse direction of the central disc 22. The purpose of the chamfers 70 is to remove contaminants sideways from the top of the base 26.
    According to another embodiment, the recess may alternatively also be a recess between the side surfaces of the foot part, which is not continuous over the entire width of the foot part. In this case, instead of the lower slot, a protrusion corresponding to the width of the recess must be formed in the adhesive patch, which is inserted into the recess. Figures 4a to 4c show an embodiment of the gripping tab 16. The gripping tab 16 is a plate-like body, which is preferably laser-cut from a single hardened metal plate. The thickness of the adhesive patch may be 6 to 20 mm, preferably 10 to 14 mm. Each gripping tab 16 preferably includes a central portion 48 comprising a lower groove 42 for securing the gripping tab 16 to the recess 24 of the center disc 22 of Figures 3a to 3c and the upper groove 44 for mounting means 20, and wing portions associated with the central portion 48.
    50. Each wing portion 50 has a lower surface 52 closer to the central disc 22 and an upper surface 54, respectively, on which the contact surface 18 is formed. By contact surface 18 is meant the surface of the feed roller that contacts the wood during its feeding. The lower surface 52 and the upper surface 54 of each wing portion 50 are angled relative to the plane 28 of the center disc 22 to increase the diameter of the feed roller 10 away from the plane 28 of the center disc 22. In addition, the lower surface 52 and the upper surface 54 are also preferably at an angle to each other, with the wing portions 50 tapering away from the plane 28 of the central disc 22. That is, the wing portions rise from the center portion 48 upwardly, with an angle of 135 to 155 ° formed between the contact surfaces 18 of the various wing portions 50, i.e., the wing portions 50 form an o v-shaped structure for centering the wood in the center of the feed roller. S 25 g The contact surface 18 of each gripping patch 16 preferably includes O teeth 32 which are protruding parts from the contact surface 18. = Teeth can also be called chisels. Each tooth 32 has a long planar surface 34 in the operating position = 30 above the tooth 32 and a short planar surface 36 in the operative position 2 below the tooth 32. The long planar surface 34 and the short N planar surface 36 are at an angle to each other and meet each other at the tip 38 of the tooth 32. The tooth 32 tip 38 is attached to the center disc closer to the center disc than the long plane surface 34 and the contact surface 18 or the short plane surface 36 and the contact surface 18. The angle oa is 35--55%, most preferably 45 °. The teeth 32 on both contact surfaces 18 are thus directed towards the center of the feed roller. As the bark blades of the bark rotor of the peeling machine rotate and apply to the wood a tangential force in the cross section that tends to rotate the wood on the feed roller, the tips 38 of the teeth 32 bite into the wood, preventing rotation. Alternatively, the teeth may also be oriented in only one direction, in which case the feed roller must be designed so that the tip of the teeth is in the opposite direction to the direction of rotation of the bark rotor to prevent rotation of the wood. Preferably, the tip 38 of each tooth 32, i.e. the intersection of the long planar surface 34 and the short planar surface 36 of the tooth, is perpendicular to the plane of the gripping patch, creating a rectangular edge 45 at the edge of the tip 38 which acts as a gripping surface. The lower groove 42 of the gripping tab 16 is preferably considerably wider than the upper groove 44. The upper slot 44 may be 25 to 55% wide, preferably 35 to 45% of the width of the lower slot 42. In this case, the upper groove 44 and the lower groove 42 form a triangular support for the gripping tab 16. The lower recess 42 includes a bottom surface 72 which, in use, rests> 25 on the bottom of the recess 24 of the center disc 22 and side surfaces 74 which in turn rest on the foot portion 68 of the center disc 22 from the sides e. The side surfaces 74 prevent the gripping tab 16 from moving = transversely to the feed roller. The upper recess 44 comprises a second bottom surface 76 on which the fastening means 20 rest vertically = 30 and second side surfaces 78 on which the fastening means 20 2 rest transversely of the feed roller.
    N Figures ba to 5c show an embodiment of a wedge serving as fastening means 20. The feed roller includes a wedge 30 for each center disc base.
    Each wedge 30 includes a wedge-shaped body portion 56 adapted to wedge between the gripping tabs 16 and at least one substantially circular wing 58 of the feed roller 10 adapted to press the gripping tab 16 into a recess 24 in the center disc 22. The body portion 56 is wedge-shaped so that the body portion 56 grows in the direction of the feed roller circuit in the operating position away from the surface facing the center disc base.
    In other words, the dimension 11 shown in Fig. 5a is smaller than 12. The wedge-like nature of the body portion 56 is intended to harness the grip patch between the two wedges.
    In the embodiment of the wedge 30 shown in Figures 5a-bc, the wedge 30 includes two wings 58 on either side of the body portion 56. Thus, a single wedge 30 simultaneously locks the two gripping tabs 16 symmetrically.
    The upper part of the wings 58 may have second chamfers 80 to improve the durability of the wedge 30.
    The wedge 30 can be attached to a bore in the base of the center disc and its counter-threads through a central opening 62 in the middle of the body of the wedge 30, for example by means of a bolt.
    The bolt may have a diameter of 12 to 20 mm, preferably
    16 mm.
    When attaching the gripping tabs 16 to the central disc 22 as shown in Fig. 2a, the gripping tabs 16 are placed in the recesses 24 of the central disc 22 from their lower slots 42 and the wedges 30 are placed between the gripping> 25 tabs 16 on each base disc 22 base, wedging the gripping tabs 16 in the feed roller 10
    The wings 58 of the wedges 30, in turn, rest on the gripping tabs 16, more specifically on the second bottom surfaces 76 of the upper grooves 44 of the gripping tabs.
    The wings 58 of the wedges 30 = 30 are equal in width to the width of the upper grooves 44 of the gripping pads 2 16 and the width of the lower groove 42N of the gripping pads 16 is in turn equal to the width of the recesses 24 of the central disc 22.
    In other words, the wedges form a discontinuous collar,
    which tightens the gripping tabs on the center disc into a “bolt ring” formed by boreholes. As shown in Figure 2a, in one embodiment, the feed roller 10 may also include end support discs 46 that lock the distance between the wing portions 50 of the gripping tabs 16 constant while stiffening the feed roller 10. The end support discs 46 preferably include holes 84 in the gripping tabs 16 shown in Figure 4. The male pieces 86 are positioned by locking the gripping tabs 16 on the end support discs 46 in the direction of rotation of the feed roller. Transverse attachment of the feed roller 10 of the end support discs 46 to the gripping tabs 16 can be achieved by using locking pieces 88 on the inner surfaces of the end support discs 46 as shown in Fig. 2a, which are locked to the gripping tabs 16, for example by rotating bolts of the feed roller 10 (not shown). end support discs.
    A more detailed structure of the locking member 88 is illustrated in Figure 8. The locking member 88 may include a body 94 and a male member 96 projecting therefrom which fits into a hole 84 in the end support disc 46. For locking, the locking members 88 include a second opening 90 through which a bolt 90 can be fitted. to the third opening g 92 belonging to the tag 16 according to Fig. 4b.
    © = As shown in Fig. 2a, a part of the gripping tabs 16 of the feed roller 10 may be narrower in width than the gripping tabs 16 attached to the end support discs 46 = 30. Every second gripping tab 16 or even every third one may have longer gripping tabs 16. The shorter N adhesive tab 16 is shown in Figures 6a-6d. There is an open area between the shorter gripping tabs 16 and the end support discs 46 to remove contaminants through the feed roller 10.
    In addition, such a structure lightens the weight of the feed roller while also reducing the stresses on the drive and transmission of the drive shaft of the drive motor. However, the feed roller according to the invention can also be implemented in such a way that all gripping pads are of the same width and adhere or do not adhere to the end support discs. In the feed roll according to the invention, the central disc 22 may comprise 16 to 40, preferably 24 to 32 recesses 24 at regular intervals, and a corresponding number of gripping tabs 16 and wedges 30. The feed roll may have a diameter of 300 to 800 mm, preferably 400 to 600 mm and a width of 200 to 500 mm, preferably 300 to 350 mm. For example, a feed roller with a diameter of 500 mm and a width of 330 mm, made of 12 mm strong steel and comprising 28 adhesive pads, can weigh about 80 to 120 kg. o O OF
