SE511379C2 - System for bundling timer branches, tops and non-looped material - Google Patents

Abstract

The bundling occurs in stages, in a straight line and the material is gripped from the input table (2) by input rollers (3,4). One of the rollers can be lowered and raised and is stagelessly adjustable against the fixed roller, so that it automatically follows the material thickness variation. Alternatively, both input rollers are movable via pendulous arms, which attempt to hold a common material bed in the bundling equipment centre. The material is then pressed into a compressor part, where compression occurs by openable and closable articulated arms resting against one another. The material is compressed in a pre-compression stage in the compressor (5) and then in a second compressor (6) in a final compression stage. By cylinders placed between the bundling equipment chassis and the second compressor a determinable counter pressure is produced, so that a determined degree of fill in the first compressor is obtained.

Description

511 379 2 When the yarn holder has stopped, the yarn is caught by a spear and pushed down into the bundle. The cycle is repeated until the customs bundle length is obtained, whereupon the tram feed stops and a cutter saws the bundle and the yarn and by adjusting the length of the support channel (12) 5 the bundle falls after cutting to the ground or is collected for laying in high, The bundling device is driven by the carrier separately arranged system and is equipped with a mechanical or computerized control unit for starting and stopping the various work steps.

Claims (2)

10 15 20 25 30 35 511379 15 Patent claim. Device for bundling spruce (branches and tops) and unbrushed trees and other material suitable for bundling, which is collected by the wearer's grip and fed onto the bundling device's feed table (2), characterized in that the bundling takes place step by step in a straight line through the bundling device, from the feed table (2) the feed rollers (3,4), one roller of which is height-adjustable and infinitely adjustable, grip the fixed roller so that it has a floating position and thereby automatically follows the thickness variation of the material or both feed rollers movable via pendulum arms, which strive to hold their common material bed in the center of the bundling device, the material and push it into the compressor part, where compression takes place by means of openable and closable articulated arms, the material first being compressed in a pre-compression step 1 compactor (5) and then in a final compression step in the compactor (6) and by means of cylinders placed between bundles The chassis and compactor (6) of the device are obtained with a definable back pressure so that a certain degree of filling in the compactor (5) is obtained, whereupon the cylinders (8) move the compactor (6) and the yarn holder (7) one step, the feed rollers (3,4 ) stops and compressor (5) pre-compresses, compressor (6) opens and the cylinders push back compressor (6) and the yarn holder (7) wraps yarn around the bundle for binding, whereupon the cycle repeats to the desired bundle length, after which the yarn is locked and the cut value (10) cut the bundle and the tying yarn. Bundling device according to Claim 1, characterized in that the yarn holder (7) consists of a circular magazine in the space of which one or more balls of yarn are stored interconnected and the yarn holder is mounted on a pivot ring in the center of which the bundle (1) is fed and the final compression wraps the yarn holder a definable number of turns of yarn with a definable clamping force around the bundle, whereupon the yarn is caught by a spear controlled by cylinder (9), which pushes the yarn into the bundle for locking.
