RIMOITUSLAITE - RIBBEHANDLINGSANORDNING

The present invention relates to a stripping device for the automatic positioning of intermediate spacers required in sawn timber packages or stacks, which stripping device comprises a strip dispensing conveyor and a carriage for moving the rails perpendicularly to the conveyor by means of wheels along the rails.

Until now, the insertion of spacers between the board layers brought into the board package by the layer dispenser mentioned in Finnish patent 54580, for example, has taken place exclusively by hand. However, this is slow and inaccurate. It is difficult to get the ribs exactly where you want them. In addition, it unnecessarily ties labor into such a monotonous phase of work.

With the stripping device according to the present invention, the stripping takes place automatically in such a way that, while the board layer dispenser is picking up a new board layer, the stripping device places spacers at regular intervals on top of the previous board layer.

The device according to the invention provides a decisive improvement in the packing speed and the accuracy of the stripping. The invention is characterized in that the bar holder arms are pivotally articulated by bar holders, by means of which the bar holder arms carry the bars onto the board layer, while a layer dispenser operating on the opposite side of the board package picks up a new board layer. The strapping device and the floor dispenser of the board package are thus fixedly connected to each other so that the mutual distance between the carriages moving these remains constant throughout the process.

Furthermore, the stripping device according to the invention is characterized in that the strip holders are pivoted by means of pivot rods which are articulated at one end with respect to their longitudinal axis to a pivotable axis by means of a hydraulic cylinder.

It is also characterized in that the height of the bar holding arms is adjustable by means of a hydraulic cylinder and levers and their four-point connection. The four-point connection has the advantage that the bar holding arms remain horizontal at all times, and thus there is no fear that the bars will slide out of their holders.

The stripping device according to the invention is further characterized in that the notches of the dispensing conveyor of the strips are depressed when the rod holding arms lower onto the levers which raise the rod.

The most important advantage of the invention is that the packaging of sawn timber, such as board, is substantially faster.

In the following, the invention will be explained in detail with reference to the accompanying drawings.

Figure 1 shows a side view of a lumbering device according to the invention and a sawn timber layer dispenser connected to it in the stage where the bar holding arms are above the board package.

Fig. 2 shows the same as Fig. 1, but at the stage where the bar holding arms are above the bar dispensing conveyor.

Figure 3 shows a top view of the stripping device.

Figure 4 shows the chain of the dosing conveyor of the ribs from the side.

Figure 1 shows how the carriages of the stripping device and the sawn timber lifter are connected to each other. So they work at the same pace. The stripping device comprises a strip dispensing conveyor 5 consisting of two parallel chains with notches 16 spaced apart by two successive strip holder arms 3. These notches pick up the strips coming to the dispensing conveyor one at a time. The conveyor advances until the first bar 15 reaches a predetermined point. Around 3,69037 strikes, the chains stop and the upper bar arms are started to lower by the hydraulic cylinder 10 and the levers 11, 12, 13 and their ne-point connection. When lowering, the bar holding arms 3 push the levers 17 downwards, which in turn raise the rod 18, which causes the notch 16 articulated in the chain to depress. The chains then move until the bars collide with the bar holders 3 with pivoting bar holders 4. By means of the hydraulic cylinder 10 the bar arms are raised again, whereby the carriage 9 starts to move on the rail 1 by means of the wheels 2 and conveys the bars above. The bar holding arms lower onto the board layer just brought by the pallet layer dispenser, after which the hydraulic cylinder 6 turns the shaft 8 so that the bar holders 4 turn out from under the bars via the pivot bars 7 and the bar on top of the slats of the board layer.

The invention is not limited to the embodiment shown in the description and in the drawings, but can be modified within the scope of the appended claims.
