    25 30 534 05 In the following, the invention is described in more detail by means of examples by referring to the accompanying drawings, in which Figure 1 shows a part of a timber conveyor according to the prior art seen from above, Figure 2 shows a trolley of a timber conveyor according to the prior art seen in the transport direction, Figure 3 shows a trolley in a trolley according to the invention, and Figures 4a-4d show simplified principle drawings of the various embodiments of the invention seen from above.
    Figure 1 shows a timber conveyor 1 according to the prior art. A conveyor chain 4 runs in a depression / groove on the frame 2 of the timber conveyor 1. A conveyor trolley 5 has been clamped at the conveyor chain 4. The clamping is done e.g. with bolts 6.
    The trolley 5 consists of a shaft 7, at both ends 8 and 9 of which wheels 10 have been mounted.
    The wheels 10 run on planes 11 on both sides of the recess / groove 3 in the frame 2 of the timber conveyor 1. The lateral movement relative to the direction of movement of the whole formed by the conveyor chain 4 and the trolley 5 is prevented at the edges 12 of the timber conveyor frame wheels 10 in the lateral direction.
    Figure 2 illustrates in simplified form a cross-section of a timber conveyor 1 according to the prior art at the trolley 5. The conveyor chain 4 runs in the recess / groove 3 of the frame 2 and the wheels 10 run on the plane 11 of the frame. At the conveyor chain 4, e.g. welded a lower disc-like seam piece 13, at which with bolts 6 an upper disc-like fastening piece 14 has been clamped, which is e.g. welded to the trolley 5.
    The fastening piece 14 can also be a uniform casting piece together with the rest of the trolley 5. Thanks to the clamping which takes place with bolts, the trolley 5 can be easily replaced if necessary. The ends 8 and 9 of the shaft 7 of the trolley 5 do not extend from the wheels 10, the ends 8 and 9 of the shaft 7 not hitting the edges 12 of the frame 2 of the timber conveyor 1 when the conveyor chain 4 fl is moved in the transverse direction. In addition, the transverse clearance between the wheels 10 and the edges 12 of the timber conveyor body is smaller than between the conveyor chain 4 and the timber conveyor body 2, the conveyor chain not hitting the timber conveyor body at all in the lateral direction. There is also a gap between the lower part of the conveyor chain 4 and the frame 2 of the timber conveyor, the conveyor chain not hitting the frame 2. Above the shaft 7 of the trolley 5, e.g. by welding fixed V-shaped supports 15 formed by 10 15 20 25 30 35 534 05 fl akkjäm, on which the log rests during transport. As a second alternative, e.g. the trolley 5 and the V-shaped supports 15 are cast in one piece.
    Figure 3 shows a new model of a trolley 5 trolley according to the invention, seen in the longitudinal direction of the conveyor. The trolley can furthermore be made in one or two pieces, as described above. It is essential, however, that the trolley 5 comprises at least two projections 16 extending in the longitudinal direction of the timber conveyor, forwards and backwards, which projections protect at least partially the soft coating of the wheel 10 against impacts of the root end of the log or any other projection when the log arrives at the conveyor. The projections 16 are preferably clamped e.g. by welding at a V-shaped support 15. The shape of the projections 16 can be selected, but it is essential that the projections prevent the log from hitting the soft surface material of the wheel 10. Preferably, the projections 16 extend almost over the entire width of the support 15 in the transverse direction of the timber conveyor and project in the transverse direction of the timber conveyor so far that they extend, seen from above, almost as far as the radius of the wheel 10, corresponding to or even outside the radius.
    The projections 16 can be manufactured so that they also extend over the support 15 in the transverse direction of the conveyor, whereby a better protection of the wheel is obtained. The pin-shaped projections placed at a distance from each other in the transverse direction also produce the same effect as the projections 16. The trolley 5 can also be arranged to run on two guides, the conveyor chain running in an open space between the guides.
    Figures 4a-4d show a number of preferred embodiments of a trolley 5 according to the invention. Figure 4a shows a two-part projection 17 of e.g. fl akkjäm, fastened with welding on both sides of the trolley 5. In Figure 4b the projections are formed by six pins 18 on both sides of the trolley 5. In Figure 4c only two pins 19 have been used on each side of the trolley 5. Figure 4d shows one of the trolleys. triangular projection 20, which widens towards the outer edge of the conveyor. A triangular projection 20 can be made to extend in the transverse direction also so that it covers, seen from above, at least a part of the wheel 10, or even extends over the entire wheel. In the longitudinal direction, the projection 20 can extend almost as far as the radius of the wheel, corresponding to the dimensions of the radius or even outside it. Essential for the invention is that the projections 16, 17, 18, 19 or 20 prevent the log from hitting the soft surface material of the wheel. In other respects, the design can take place at your own discretion. The pins 17 and 19 in the examples can also be triangular projections seen from the side, obtaining a more stable clamping of the supports at trolley 5. In the preferred embodiments described above, the projections 16, 17, 18, 19 or 20 can be made of a profile. a fl chisel or cast in one piece together with the V-shaped support. 10 534 05 In addition, the body of the carriage together with the projections 16, 17, 18, 19 or 20 can be made of composite material or plastic.
    The above-mentioned improvement of the trolley according to the state of the art significantly prolongs the service life and service intervals of the trolley wheels, and reduces the conveyor's energy consumption and noise level, as softer wheel material can be used.
    Only a few forms of the invention have been exemplified above. However, the invention is not limited to the examples described, but may vary within the scope of protection defined by the following claims.
