Definitions

  • the invention relates to a device, a system and a method for producing and handling bundles of staple goods such as logs, such as those used in the processing of firewood.
  • Such devices are the subject of the publications CH120123 . EP 0 897 867 A1 . FR 2822135 A1 and US 4,057,262 ,
  • This instability is due to the fact that in the manufacture of bundles of staple material with irregular cross-section and circular waist circumference, the circumferential force of the tension belt leads to the formation of a positive connection in the region of the waistband circumference. As a result, the tension belt can not compress the central region of the federal government. For example, this leads to the production of bundles of logs to the fact that fall out of the central collar area in handling the bundles logs.
  • a system for bundling, cutting, stocking, volume determination and transport of firewood in which a bundle of firewood created for compact processing is prepared for firing desired final length for a handy onward transport to the firing point.
  • a device which consists of at least two individually movable units, which are coupled to each other in the federal axis direction, that between the units the AblCodeitese are feasible.
  • the firewood collar is inserted into the system, for which each unit has an upwardly open, semi-circular receptacle that is compatible with the geometric shape of the male collar.
  • the inserted firewood bundle is cut between the units by a single cutting cut.
  • at least one unit of the system can be individually and independently of the other units, loaded with the cut firewood, proceed to the Ver85ungsstelle.
  • This system is thus primarily suitable for the production of logs in the desired kiln length and for the firing in the rhythm of Feuerungs loces.
  • For the preparation of a stock also a variety of units of the system is needed, which is relatively space and cost intensive.
  • this system For the production of bundles with the content of a room meter and a weight of about 600 kg, this system is also not suitable because u. a. too heavy for the units of the system. Nor can the standard amount of logs of one meter of bulk produced economically.
  • a device for the manufacture of firewood pieces and / or firewood coils known, which has a lateral connection plate and two aligned with this and at an axial distance from each other and upwardly open semicircular bracket for receiving the firing.
  • the front bracket is rigidly mounted on a frame member, while the rear bracket and / or the stop plate are arranged axially displaceable.
  • This device primarily serves the sawing off of the inserted firewood in the desired length, but is in principle also suitable for bundling inlaid logs. Although no statement is made about the way in which bundles are bundled, only the usual lashing over straps or strapping can take place here. This also remains in the interior of the interior only an insufficient holding voltage, so that the inner logs can fall out during transport.
  • the object of the invention is therefore to provide a device, a system and a method of the type described above for producing and handling / transporting staple goods which are simple and safe and by which during manufacture, but also when handling bundles of bundles, the central area of the bundle is compressed and remains so that no logs fall out of it.
  • the device according to the invention of two on a base plate, preferably a Euro pallet, oppositely mounted support brackets.
  • a first support bracket is arranged so as to be displaceable on the base plate, while a second support bracket is displaceable parallel to the first support bracket on the base plate from a first position, the basic position for loading, in a second position spaced from the first support bracket or other positions.
  • the insertion longitudinal axis of the device which is also the longitudinal axis of the federal government to be created, extends between the two support blocks in their first position.
  • each support bracket consists of two in the direction of the insertion longitudinal axis of the device parallel to each other and mutually firmly connected side walls.
  • the second support bracket is provided with an axially oriented belt deflection, which projects radially into the interior of the recess.
  • a tensioning lock via a turnbuckle and tensionable strap is provided, which is so feasible around the federal government, that it is deflected engaging over the belt deflection in the Bundinnere.
  • the circular segment-shaped recess is a total of over 180 °, preferably about 270 ° (135 ° per support bracket).
  • the recess is pulled in cross section far above a semicircle, whereby the circular shape bond of the Federal Government is much higher.
  • the logs can be safely and accurately inserted to the upper vertex of the covenant, without the risk that an uneven shape of the collar is obtained and / or slip off the slabs laterally when layering.
  • the belt deflection consists of an axially oriented rod or strip, which is supported at its two ends in horizontal-radially projecting from the support walls of the support bracket holding arms.
  • the clamping force of the belt acts radially-horizontally on the belt deflection, whereby the bearing force on the outer lower end of the support bracket and thus the frictional force acting between the support bracket and base plate is increased. It adjusts an equilibrium of forces between the belt force, the bearing force acting on the support block federal force and the frictional forces between the support bracket and the base plate.

    - les bûches de bois étant ensuite insérées dans les logements d'insertion (7) jusqu'à l'obtention de la forme ronde correspondante du paquet,
    - l'extrémité libre de la sangle étant ensuite levée et posée par-dessus le paquet (6) empilé, dans lequel elle est insérée et enfilée dans la fente (49) du tube d'enroulement (48) du tendeur (14) fixé de manière autobloquante à l'autre extrémité de la sangle d'une manière telle, que la sangle de serrage est soumise à un premier serrage d'enroulement,
    - à l'aide d'une clé à cliquet (54), le tube d'enroulement (48) du tendeur (14) étant ensuite mis en rotation moyennant quoi la sangle de serrage est enroulée et la tension de la sangle augmente de manière correspondante, la sangle de serrage (13) exerçant une force de déplacement radiale sur le renvoi de sangle (8) s'étendant radialement vers l'intérieur du paquet,
    - le levier de verrouillage (36) sur le chevalet mobile (3) étant aussitôt desserré, moyennant quoi, de façon correspondante à la tension de sangle, le chevalet (3) est déplacé vers l'extérieur, dans lequel on continue de tendre de façon continue en actionnant la pédale jusqu'à ce que le renvoi de sangle (8) soit complètement poussé hors de l'intérieur du paquet,

  13. Procédé selon la revendication 12, caractérisé en ce que,
    pour le déplacement continu du chevalet (3) avec la tension souhaitée de la sangle de serrage (13), on actionne respectivement au moins brièvement la pédale (32) pour le réglage de la tension de la sangle, laquelle pédale bascule ce faisant et réduit la force d'appui de la nervure (30) qui la traverse sur les planches de couverture de la palette, et ainsi la friction entre la palette et le chevalet.
  14. Procédé selon la revendication 12, caractérisé en ce que,
    après avoir réalisé la tension optimale de la sangle via le tendeur (14) et le déplacement longitudinal suffisant du chevalet (3), le paquet (6) est extrait vers le haut via le préhenseur de sangle auto-serrant (58).
  15. Procédé selon la revendication 12, caractérisé en ce que,
    après avoir réalisé la tension optimale de la sangle via le tendeur (14) et le déplacement longitudinal suffisant du chevalet (3), le paquet (6) reste sur la palette (1) pendant que les deux chevalets (2, 3) sont soulevés de la palette et sont amenés vers une réutilisation ou utilisation ultérieure éventuelle correspondante en rapport avec une euro-palette vide, dans lequel la palette avec le paquet en appui pour ne pas partir en roulant, par exemple via des cales, est emporté par exemple à l'aide d'un chariot élévateur ou gerbeur.
