FR2859178A1 - Billet bundle roping machine for use on e.g. elevator, has frame lifted by engine and including fixed cradle that oscillates on pivot when activated by hydraulic jack for causing auto-tightening of ropes - Google Patents

Abstract

The machine has a frame (1) lifted by an engine to a desired height and including a fixed cradle (2) that oscillates on a pivot (5) when activated by a hydraulic jack (6). The cradle (2) has a diameter of 1.13 meters for receiving billets of 1 meter length. A removable cradle with 1 meter diameter, receives billets having length of 0.5 meter. The swinging of the cradle (2) causes auto-tightening of ropes.

Description

The present invention relates to the design of a packaging machine

  firewood in standardized round boots of a stere by binding. (in logs of 0.50mou1m).

  When trimming the boots, the chucking of the chords is usually done manually by means of ratchet pins.

  The present machine by design achieves a binding of the boot by self-tightening remedying this tedious step of conditioning.

  By using the tilting of the boot in a metal cradle, as well as its own weight, one obtains by quick knots a fast and effective tightening of the cords.

  This portable machine by agricultural machine or elevator has the advantage with the total swing of the cradle to stack the boot on several levels in height, facilitating stacking and storage.

  The use of this machine represents a lower cost of packaging, it is lost, but cheap compared to pallet deliveries that require plastic packaging more instructions.

  Due to the absence of packaging, the space saving is increased on the vehicles, the gripping is easy by hydraulic clamp and the secure loading.

  The self-tightening of the boot is achieved by the tilting of a metal cradle semicircular shape provided with a round bottom plate forming a template.

  The tilting is caused by the action of a hydraulic cylinder giving a pivoting of the cradle from 0 to 90.

  After having previously installed and jammed the 2-3-4-5 cords (Fig. 3 and 5) between the fingers and notches provided in the cradle, the cradle is loaded with wood manually until the sheet metal is flush .

  The 2-3-4-5 ropes are brought back to the boot, flowing knots are made manually. The ropes are then manually tensioned and then stowed two by two summarily to a fixed amount of the machine. The machine is lifted from 20 to 30 cm. The cylinder is actuated, the cradle rocking causing the automatic tightening of the cords. Tips at the bottom of the cradle prevent the boot from turning on itself during tightening.

  The ropes are then cut and tied. The four strings being in tension at the same time, there is no loosening during the binding. For boots in 0.50 m, the same operation is performed for rope 1 (Fig. 5).

  The boot is ready, the machine lifted (according to the machine) to the desired height, the cradle 35 is tilted completely by the jack, the boot is extracted from itself and falls.

  The accompanying drawings illustrate the invention.

  Figure 1 shows the machine from the front, at rest.

  Figure 2 shows the machine seen from above.

  Figure 3 shows the machine loaded during autosserrage. Figure 4 shows the stacking machine of the boot.

  Figure 5 shows the particular alignment of a boot in 0.50 m.

  With reference to these drawings, the machine comprises a frame (1) adaptable agricultural tractor lift, front fork or elevator deck. This frame (1) supports a metal cradle (2) of semicircular shape, built in U bent mechanically welded, oscillating on a pivot (5) from 0 to 90, operated by a hydraulic cylinder (6).

  The cradle (2) with a diameter of 1.13 m for log bundles of 1 m receives the removable cradle (3) with a diameter of 1 m for 0.50 m log bundles fixed by four bolts. The stacking density is not the same between logs 1 m and 0.50 m in stere, the cradle (3) is provided for boots 0.50 m. This one for the sake of clarity is only shown in fig. 1.

  The bottom of the cradle (2) is composed of two assembled sheets (11) forming two separate templates, one of 1.13 m (logs of 1 m) and the other of 1 m (logs 0.50m).

  The frame (1) supports the uprights (7) having notches at the top and (8) cylindrical, the cleat (10). These allow the rough tie-down of the ropes and the 20 tend when self-tightening.

  A sheet metal tray (9) contains a reserve of four reels of rope.

  The two points (4) welded in the bottom of the cradle (2) prevent the boot from turning on itself during self-tightening.

  The twelve fingers (12) fig. 2 welded on the cradle allow to position and jam the cords 2-3-4-5 fig. 3 before loading wood.

  The notch (13) fig. 1 on the bottom plate to position the rope (1) fig. 5 (boots 0.50m).

  For boots in 0.50 m, two logs a and b of 1 m fig. 5 are integrated in the middle of boots to stiffen the two half-boots. Everything is secured by the rope (1) in the last place. For 1 m logs, 2-3-4-5 ropes are sufficient.

Claims (4)

  1) Machine to bind firewood boots in 0.5 m or 1 m characterized in that it comprises a frame (1) levable by gear at desired height. This frame (1) supports a cradle (2) pivoting on pivot (5) from 0 to 90 actuated by hydraulic cylinder (6). This cradle (2) standard 1.13 m diameter for logs 1 m can receive a removable cradle (3) diameter 1 m for logs of 0.50 m.   2) Machine according to claiml) characterized in that the tilting of the cradle (2) by means of the jack (6) causes self-tightening cords 23-4-5 fig. 3 and 5 stowed two by two summarily to the amounts (7).   3) Machine according to claiml) characterized in that the tilting of the cradle 10 (2) + (3) by means of the jack (6) causes the self-tightening of the rope 1 fig 5 stowed briefly to the cleat (10) and passing through the cylindrical support (8).   4) Machine according to claim 1) characterized in that the stacking of the boot is obtained by completely tilting of the cradle (2) to selected height fig. 4 for removing the boot.
