Abstract
This production line consists of a line saw 16 which is placed horizontally and of 6 carrying trolleys 1, 2, 3, 7, 9 and 13 onto which logs to be cut are affixed and of two auxiliary trolleys 8 and 14 which transport carrying trolleys from the main rail 5 to the rail for the saw 12 and from the rail for the saw 12 to the main rail 5. Carrying trolleys 7, 9 and 13 carry one log (each trolley) and they 'circle around' from the main rail 5 onto the auxiliary rail 6, then onto the rail for the saw 12, onto the auxiliary rail 4, until they cut the entire thickness of all three logs. During the cutting of the first three logs, on the auxiliary line placed are carrying trolleys 1, 2 and 3 onto which placed and affixed are three new logs, which go to the main rail 5, while carrying trolleys with the cut logs move onto the auxiliary line for loading of new logs. This production line has no idling and it can saw 3 times larger quantity of timber than it is done in a saw-mill of the same techical characteristics. Besides this, on this line cut is the timber (which is used as firewood due to being bent) of up to 1.5 m length which is then commercially marketed at a several times bigger price per m3.
Description
PRODUCTION LINE FOR MANUFACTURING WOODEN ELEMENTS OF UP TO
1.5 M LENGTH
1. SUBJECT TO WHICH THE INVENTION APPLIES
This invention applies to the production line for manufacturing of wooden elements of up to 1.5 m length which consists, among other things, of six carrying trolleys, two auxiliary trolleys, horizontal belt saw and automatics which operates the production line, according to the international patent classification (MKP), classified as B 27 B 15/00, line or belt machines for sawing specially intended for longitudinal sawing of logs.
2. TECHNICAL PROBLEM
The problem is that in existing saw-mills a log is placed onto a saw, one board is cut and the log has to be put back into the initial position in order for the next board to be cut, causing a reverse idling. Also, this invention solves another problem - e.g. on this line the logs of up to 1.5 m length can be cut. These short logs have been cut from a longer log which was bent, not being straight, this being the reason for cutting off a part of the log in order to leave the remaining part of the log straight.
The cut piece of up to 1.5 m length, as a rule, was used as firewood. On this line such logs are cut into elements which are used for building chairs, table legs, fence posts, stair treads - thus getting timber which is used comercially at higher prices than at those of firewood.
3. STATE OF THE TECHNIQUE
The state of the technique, up till now, known to the inventor is the following: There are saw-mills for cutting logs of more than 2 m length, which after having cut one board return the remainder of the log into the initial position, move the saw by one width of the board and
l
cut the next board. This being accompanied by an idling, the saw-mill losing on productivity, wasting time and energy for starting the saw while the log is being returned into the intial position. Besides, the existing saw-mills are not adapted by their construction to cutting logs of up to 1.5 m length.
4. EXPLANTION OF THE INVENTION ESSENCE AND IT'S DESCRIPTION
Fig. 1 shows the production line for manufacturing of wooden elements of up to 1.5 m length. The currenty carrying trolley 9 with its log is placed before the line saw 16, horizontally placed onto the main support (prop/girder) 11 and post 15. The carrying trolley 9 move on rails for the saw 12 by means of chains and supporting pulleys.
While a log is being cut on carrying trolley 9 at the same time carrying trolley 13 with its remainder of the log meets the carrying trolley 14 which is then being transported by the auxiliary rail 4 to the main rail 5. At the same time the carrying trolley 7 on the auxiliary trolley 8 is being transported on the auxiliary rail 6 before the line saw 16 which is being lowered by one thickness of a board and thus the log on the carrying trolley 7 goes for cutting. In this moment the carrying trolley 13 is placed on the main rail 5, the auxiliary trolley 14 is retrning before the rails for the saw 12 and taking over the carrying trolley 9 together with the remainder of its log. Empty auxiliary trolley 8 returns to the main rail 5 and takes over the carrying trolley 13, transports them before the rail for the saw 12 for cutting.
In this way the auxiliary trolleys 7, 9 and 13, with their logs "circle around" until their logs are cut all the way. The saw 16 is being lowered by the thickness of a board once for all three logs and there is no idling, because the logs are carried on the rails for the saw 12 one after the other.
During "circling around" time of the logs on the carrying trolleys 7, 9 and 13 around the saw
16 to be cut, on the auxiliary rail logs of approximately equal thickness are being put on the carrying trolleys 1, 2 and 3 and squeezed by squeezers, prepared for cutting.
When the last log on the trolleys 7, 9 and 13 comes to the auxiliary rail 6 at this moment the carrying trolleys 3, 2 and 1 by means of the auxiliary trolley 14 are transported from
immediately after the last trolleys 7, 9 and 13. As the carrying trolleys 7, 9 and 13 are doing the finishing cutting of all logs by means of the auxiliary rail 4 they go to the auxiliary rail for loading of new logs.
This is a continuous process and the complete line is automatized providing for higher productivity.
This production line does not have any idling and any waiting for a new log to be loaded and prepared for cutting. Thus a three times bigger quantity of timber can be cut than the quantity at a saw-mill of the same technical characteristics.
If needed, in this production line a log of up to 4 m can be cut so that a log is placed on two carrying trolleys before the saw 16, a board is cut by passing through the saw 16, returned into the intial position, the saw 16 is lowered by the next thickness of a board and is being cut in the same way as it is cut in a regular saw-mill.
