Definitions

the invention relates to a method for dividing logs into a plurality of log sections of a predetermined length according to the preamble of claim 1.
a method of the type mentioned is known (DE-OS 28 42 935). After the round wood conveyed in its longitudinal direction has been cut to length by the first saw cut so that a round wood piece is formed, the length of which corresponds to the sum of the predetermined length of at least two round wood sections to be produced, this round wood piece is transferred to a conveyor bed by a cross transfer device, there. positioned in its longitudinal direction and - while it is resting on the conveyor bed - divided into the desired log sections by a further saw cut. While this second saw cut is taking place, no further piece of round wood can be transferred and no longitudinal positioning process can be carried out on the conveyor bed.
the working speed of the known method is therefore limited by the fact that the work steps of transferring the log piece to the conveyor bed, the longitudinal positioning of the log piece on the conveyor bed, dividing the log piece into the desired log sections and further transport can only be carried out one after the other in time.
the object of the invention is therefore to provide a method of the type outlined in the preamble of claim 1 in such a way that a substantial increase in working capacity, i. H. throughput of logs is achieved in order to allow adaptation to the increased capacities of modern sawing and profiling systems.
This object is achieved in that the further saw cut is carried out when the log piece is conveyed in the transverse direction, while at the same time a further, first saw cut is carried out.
the known method has achieved a temporal and spatial staggering of the saw cuts, with the first saw cut being carried out on a conveyed log log when the previously cut log piece is still subjected to the second saw cut.
This allows a significant increase in the capacity for the cutting process to be achieved with comparatively little effort.
This makes it possible to load modern, high-performance sawing and profiling systems with a single one-piece station, which avoids the considerable human and technical extra work for a second one-station, otherwise would be necessary to achieve an adjustment of the loading speed to the working speed of the sawing or profiling system.
the simultaneous execution of several saw cuts on the same log which could also bring about an increase in capacity, would be associated with considerable difficulties which stand in the way of practical implementation.
the devices according to FIGS. 1 and 2 and according to FIGS. 3 and 4 have in common that the log 1 to be cut is conveyed upwards in the longitudinal direction on a chain conveyor track 2 and fed to a first circular saw 3 which is arranged in a gap in the chain conveyor track 2 .
the chain conveyor track 2 is connected to a positioning device, not shown, which has, for example, fold-away and / or longitudinally adjustable stops or which - as provided in the exemplary embodiment shown - has a pulse control with which the previously measured log 1 is conveyed to the position in which the circular saw 3 cuts off a piece of round wood 1 a with a first saw cut, in that the circular saw 3 is advanced transversely to the chain conveyor track 2.
the length of the cut log piece 1a corresponds in the example according to FIGS. 1 and 2 to the sum of the lengths of two log sections 1b and 1c which are to be achieved by the distribution process.
the cut round piece of wood 1a has a length which corresponds to the sum of three round wood sections 1b, 1d and 1e taking into account the saw cut joints.
the log piece 1a is ejected by a transverse transfer device 4, which has, for example, movable punches, onto a roller conveyor bed 5 arranged parallel to the chain conveyor bed 2.
a transverse transfer device 4 which has, for example, movable punches
the piece of log 1a is in its Moved in the longitudinal direction and positioned by moving z.] 3 against adjustable stops 6.
the roller conveyor bed is located in the region of an ascending chain cross conveyor 7, which has a plurality of chains 8 arranged next to one another, each of which is provided with drivers 9.
the cross conveyor 7 is driven intermittently and takes over with its drivers 9 in each movement step: a log piece 1a from the roller conveyor bed 5.
the log piece 1a When the log piece 1a is conveyed crosswise, it is moved against a further circular saw 10 arranged in the area of the cross conveyor 7, which cuts the log piece 1a into the Sections 1b and 1c divided, the predetermined length of which was set by the positioning process on the roller conveyor bed 5.
the log sections 1b and 1c at the upper end of the cross conveyor 7 arrive at a pivotable transfer device 11, through which they are fed to a chain longitudinal conveyor 12, which carries the log sections 1b and 1c, for example, to a sorting device downstream sawing and profiling system promotes.
the transfer device can be divided into separately operable sections in order to enable the individual transfer of the individual log sections.
the circular saw 10 is mounted on a swivel arm 13 which can be swiveled by means of a pressure-actuated cylinder 14.
a pressure-actuated cylinder 14 Depending on the thickness of the log, two different ways of working are possible. While the circular saw 10 is constantly in its upper position when cutting thinner round wood and the round wood is moved by the cross conveyor 7 against the circular saw 10 If the log is stronger, the log is conveyed into the sawing position when the circular saw 10 is initially lowered. In this position, the log is held by a hold-down device 15 only indicated in FIG. 2, while the circular saw 10 is pivoted upwards by the cylinder 14 and sawed through the log.
the embodiment according to FIGS. 3 and 4 differs from the embodiment according to FIGS. 1 and 2 in that only the one log section 1b, which was separated from the log piece 1a when passing the circular saw 10, by the chain cross conveyor 7 in the described way to the chain conveyor 12 is moved.
the log section 1c is fed by a shorter chain cross conveyor 7 'after the saw cut to a further roller conveyor bed 16, on which the log section 1c is positioned by longitudinal movement against an adjustable stop 17.
a further chain conveyor 7 ′′ also arranged in an ascending manner, lifts the log section 1c from the roller conveyor bed 17 and feeds it to a circular saw 18, which is designed and arranged in a corresponding manner, as was described in connection with the circular saw 10
Circular saw 18 divides the log section 1c into log sections 1d and 1e, which are then also transferred to the chain longitudinal conveyor 12 by a transfer device 11 '.
the method according to the invention can also be carried out in such a way that no circular saw 3 is provided in the area of the chain longitudinal conveyor device 2.
the log is here delivered to the roller conveyor 5 without a saw cut, positioned there in the longitudinal direction and fed to the circular saw 10.
the log section 1c separated there is then cut into the desired log sections 1d and 1e by a further circular saw 18, similar to the device according to FIGS. 3 and 4.
