Definitions

  • This invention generally relates to guide bars for sawing through or cross-cutting tree stems or logs, and especially to such guide bars as are included in so-called grapple or single-grapple harvester units of the type which comprises, in addition to a guide bar, grapple means for seizing a tree stem, feeding means for longitudinal feed of the stem relative to a frame included in the har ⁇ vester unit, and means for limbing the stem during said longitudinal feed.
  • grapple means for seizing a tree stem i.e. machines processing felled trees
  • har ⁇ vesters i.e. machines both felling and processing the trees
  • These machines are of the so-called twin-grapple "ty * 2 , i.e. the grapple unit or the combined cutting and grapple unit lifts the tree into a special processing unit generally mounted on a relatively high level, and the pro ⁇ Waitd log or piece of timber is allowed to drop down a certain distance after processing is completed.
  • the knovm equipment for colour marking of such logs comprises spray nozzles mounted on the frame of the processing unit in such a manner that paint can be sprayed onto the end of a log falling down from the processing unit. This can be done since the machines now described have a relatively large size to provide ample space for mounting the colour marking equipment in a protected fashion.
  • grapple harvesters or single-grapple harvesters comprising a single-grapple har- vester unit mounted on a vehicle-borne boom have been em ⁇ ployed to an ever increasing extent in forestry.
  • Such single-grapple harvester units include all the required functions, i.e. grapple, cutting and limbing functions in one and the same tool.
  • Such single-grapple harvesters do not offer the possibility of mounting the colour marking equipment on the tool frame in the same manner as in the machines previously mentioned. Summary of the invention
  • the present invention aims at providing colour coding or marking of log or stem ends deriving from cross- cutting of stems by means of guide bars, and especially guide bars included in so-called single-grapple harvester units.
  • these and other objects are achieved in that two or more mutually separated nozzles or holes open in at least one side of the guide bar and communicate via associated channels within the guide bar with at least one container with paint, and in that the channels are individually openable to allow selectible spraying of paint from each of the nozzles while the guide bar is sawing through a stem or log, whereby the end surfaces of cross-cut stem or log parts in an assortment of different stem or log parts can be marked with different combinations of colour impressions.

  • Fig. 2 shows such a harvester unit in a position for felling a tree 4
  • Fig. 3 shows the unit in a position for processing the tree.
  • the harvester unit is fixed by the intermediary of a rotator 5 at the boom end and generally comprises a frame 6 and a processor 7 pivotable in relation thereto.
  • the processor has two pairs of grapple arms 8, a feeding de ⁇ vice in the form of a driving belt or driving wheel 9, and a cutting device 10 having, as shown in Figs 4-6, a guide bar 11 which is pivotable relative to the frame and around the circumference of which a saw chain is rotatable at a high speed.
  • the grapple arms fullfil two functions. First, they serve to seize the stem, both in the felling position shown in Fig. 2 when the guide bar is pivoted in the horizontal plane for cutting through the tree, and in the position shown in Fig. 3 when the processor has been pi ⁇ voted in relation to the frame for placing the tree on the ground. Second, the grapple arms should limb the stem as this is longitudinally fed by the feeding device through the harvester unit.
  • the grapple arms have sharp longitudinal cutting edges for cutting off the limbs.
  • feeding is interrupted and the guide bar cross-cuts a limbed and finished log, which is done by starting the saw chain and causing the guide bar to pivot downwards from an inoperative starting position shown in Fig. 4.
  • the finally cut logs will then drop down into a heap 12 for subsequent removal.
  • Figs 4-6 are simplified side views of the harvester unit, which clearly illustrate the inventive principle.

  • Fig. 5 shows the guide bar in the process of cross-cutting a tree stem, and

  • the channels are each connected to a conduit 15', 15" provided outside the guide bar and connecting the channels to valves 16', 16" and supply containers 17', 17".
  • These containers are suitably filled with liquid paint which, when the valves are open, is supplied by means of pump (not shown) or by the hydraulic pressure of the machine through the conduits 15', 15" and the channels 13', 13" and sprayed through the nozzles 14', 14".
  • the guide bar is shown in its inoperative starting position in which the stem can be longitudinally fed through the har ⁇ vester unit. When the stem has been fed a suitable distance, feeding is interrupted and cutting initiated by rotating the saw chain and causing the guide bar to pivot downwards, as shown in Fig. 5.
  • valves 16', 16" can be caused to open at a predetermined, suitable position of the guide bar, such that paint will flow from the containers and be sprayed through the nozzles onto at least one of the two end surfaces 18 thus formed.
  • the re ⁇ sult in this case is a log surface exhibiting two stripes of paint 19.
  • different timber assortments can be marked to facilitate subsequent sorting and hand ⁇ ling.
  • the invention may be modified in many different ways within the scope of the accompanying claims.
  • the number of channels and the position of the nozzles may be varied.
  • the illustrated embodiment of the arrangement according to the invention is mounted on a single-grapple harvester unit, it is of course quite possible to use the invention on all existing devices equipped with a guide bar, i.e. also on processors and twin-grapple harvesters as well as simple power saws.
  • the paint need not necessarily be a liquid. Thus, it may instead consist of a powder, paste or the like.

Abstract

La présente invention se rapporte à un agencement de marquage en couleur monté dans une barre de guidage (11) servant à scier ou à couper transversalement des branches ou des troncs d'arbres. Au moins deux buses ou trous mutuellement séparés (14', 14'') débouchent dans au moins un des côtés de la barre de guidage et communiquent par des canaux associés (13', 13'') à l'intérieur de la barre de guidage avec au moins un récipient (17', 17'') contenant de la peinture. Les canaux peuvent s'ouvrir séparément pour permettre une pulvérisation sélective de peinture depuis chacune des buses (14', 14'') pendant que la barre de guidage coupe transversalement une branche ou un tronc, les surfaces terminales des parties de branche ou de troncs coupées transversalement dans un assortiment de différentes parties de branche ou de tronc pouvant être marquées par différentes combinaisons d'impressions de couleurs.
