Finland-Finland (FI) (72) Teuvo Lehtikuusi, Kitee, Finland-Finland (Fl) (5U) Device for tying timber bundles - Anordning för bindning av 100

The invention relates to a device for tying bundles of timber, in particular log bundles in a sorting basin. Such tying of log bundles is necessary when the logs are sorted in a so-called into water as a sort.

In practically all sawmills, logs are sorted before sawing, e.g. based on tree species, top diameter and quality. Sorting is usually carried out either on land or in water by means of a sorting plant. In sorting in water, the logs are transported longitudinally in succession by a conveyor mounted on the water. Sorting trays are formed on the sides of the conveyor, into which the logs transferred by the conveyor are brought. The sorting trays have no bottom and the logs float in the water. When one sorting tray is full, the logs in it are tied into a bundle. The bundle is then transferred in one way or another to the saw. Naturally, the bundle is unloaded again before feeding the logs to the saw. The purpose of bundling is to help the different grades stay separate and to facilitate the transfer of logs, which usually takes place by floating. In addition, bundling naturally prevents the formation of sunken logs.

It is known to use e.g. thick iron wire, chains and ropes made of artificial material. These all have their own drawbacks. Iron wires are usually disposable. In this case, the price becomes high over time. On the other hand, the collection and disposal of used yarns must also be arranged in an appropriate manner.

Forming bundles with chains eliminates the above drawbacks, but at the same time replaces a few others. The chains are usually intended for reuse. In this case, transporting them from the sawmill to the sorting site is cumbersome because the chains usually weigh quite a lot. Sometimes the chains also fall into the sorting basin.

The use of plastic ropes for tying bundles is also known. However, it is difficult to get the ropes taut enough around the bundle. Therefore, it is necessary to use at least two ropes to keep the bundle together.

By means of the binding device according to the invention, e.g. to avoid the disadvantages explained above. To achieve this, the tying device according to the invention is characterized in that the tying part is made of a lighter material than water, preferably a rope of man-made fiber.

The advantage of the device according to the invention is its easy transportability compared to chains. This is due to the lightness of the device. However, it smokes the advantages of the chain, i.e. good tightness and reusability. The device according to the invention also does not generally disappear by drowning. This is due to the fact that the lighter middle part of the water normally reaches the surface of the water, even if the connecting parts are sunk to the bottom. Thanks to the good tightenability, only one tying device is needed per bundle.

In the following, the invention will be explained in detail with the aid of the accompanying drawing.

Figure 1 shows one preferred embodiment of the invention. Figure 2 shows an end view of tying a log bundle with a device according to the invention.

According to Figure 1, the tying device according to the invention consists of a binder part 1 made of artificial material. A piece of chain 2 is attached to one end of the binding part 1. A tensioning and locking lever 3 is fitted to the last loop of the chain. A piece of chain 4 is also attached to the other end of the binding part. around the bundle regardless of the mutual splits of the bundles;

Figure 2 shows the tying of a log bundle with a device according to the invention. The sorted logs 21 is assembled in a suitably sized bundle, which is surrounded by lajittelulokerossa the tying device 22. The connecting member 23 at one end of the chain 28 attached to the tensioning and locking lever 24 in a suitable binding loop of the second end portion 23 of the chain 25 and is tightened by turning the direction of the arrow shown in FIG. The lever arm 26 is attached to the chain 25 either by a hook 27 at the end of the arm or, for example, by an iron wire,

The invention has been described above with reference to only one preferred embodiment thereof. It is, of course, to be understood that the invention is in no way limited to the example described, but that various modifications may be made within the scope of the following claims.

Claims (2)

4 61004 An apparatus for tying bundles of timber, in particular log bundles in a sorting basin, comprising a flexible binding part (1, 23) and means (2, 3, 4, 24, 25, 26, 27, 28) attached to at least one end of the binding part for tightening and locking the device in a loop shape around the bundle, characterized in that the binding part (1, 23) is made of a lighter material than water, preferably a rope of man-made fiber.
