Definitions
- the present invention relates to a sawing system and a method for sawing a material to be sawn by means of a saw.
- Log band saw systems which usually have one or two band saw frames, whose positioning in relation to one another is either fixed in a predefined manner (e.g. next to one another) or variable (at least movable in one direction with respect to one another).
- known sawing systems have a carriage which can be moved back and forth (or back and forth) by means of a drive on a track guide that defines a longitudinal direction.
- EP 0963822 A2 discloses a device for dividing
- the carriage serves as a support for a material to be sawn (for example a tree trunk), which is fixed in a predefined position on the carriage before sawing, for example by means of several clamping hooks, and transports the material to be sawn during the forward or backward movement with a certain positioning relative to the saw blade of the band saw by the band saw stand.
- a saw product e.g. a board blank
- the later thickness or strength e.g.
- the board thickness of the sawn product is determined by a pre-adjustable protrusion between the sawed material and the saw blade before sawing, in which, for example, the support of the carriage is moved in the transverse direction (perpendicular to the longitudinal direction).
- the band saw blade is usually stretched between two band saw rollers mounted on the band saw frame, and runs around them at an adjustable saw speed.
- the sawing direction of the band saw blade is usually aligned perpendicular to the longitudinal direction.
- the actual sawing step can be preceded and / or followed by further processing steps.
- the items to be sawn can be measured in advance by means of an (for example optical) measuring system.
- the so-called rind (the first piece to be separated from the material to be sawn that is not suitable for further processing) can be machined by means of a machining unit as an alternative to sawing off this rind.
- the material to be sawn can be cut or trimmed in its transverse direction, for example by means of a circular saw.
- Transverse movement transferred to a support of the carriage and rotated on this manually (for example via a remote control by an operator) or automatically (for example via a camera system) into a predetermined position.
- this position is fixed on the support with the aid of a clamping mechanism (for example, using clamping hooks).
- the material to be sawn is moved by means of a transverse movement of the support of the kind with respect to the band saw frame that a predefined protrusion arises between the material to be cut and the saw blade, through which the desired strength or thickness of the saw product to be produced is defined.
- the band saw frame can be moved in the transverse direction.
- Both the loading of the carriage and the turning or positioning of the material to be sawn on the support of the carriage requires time in which no material to be sawn can be processed. As a result, production and performance losses of the sawing system occur during this loading or positioning time, which has economically disadvantageous consequences.
- the loss of time that occurs here can amount to greater than or equal to 10 seconds per item to be sawn.
- a sawing system that includes a rail guide that defines a longitudinal direction, a saw that is arranged on the rail guide, a first drillgegutzussel, a second drillgegutzuschreib, a first carriage that has a first stakegegutauflage and comprises a first carriage drive, and a second carriage which comprises a second sawmill support and a second carriage drive.
- the first sawmill supply is set up to transfer a first sawed product to the first sawed product support.
- the second sawmill supply is set up to transfer a second sawmill to the second sawmill support.
- the first carriage drive is set up to drive the first carriage with the first item to be sawn on the rail guide along the longitudinal direction of the saw in order to saw the first item to be sawn in the longitudinal direction.
- the second carriage drive is set up to drive the second carriage with the second item to be sawn past the saw on the rail guide along the longitudinal direction in order to saw the second item to be sawn in the longitudinal direction.
- the object of the invention is achieved by a method for sawing by means of a sawing system, which has a saw, a first carriage which comprises a first saw product support, and a second carriage which comprises a second saw product support.
- the method has the following steps: transferring a first item to be sawn to the first item support; Moving the first carriage along a longitudinal direction in order to drive the first material to be sawn past the saw and to saw the first material to be sawn in the longitudinal direction; Transferring a second item to be sawn to the second item support while the first item is being sawed, and moving the second carriage in the longitudinal direction in order to drive the second item past the saw and to saw the second item in the longitudinal direction if the sawing of the first item is interrupted and / or is completed.
- the new sawing system has a saw that cooperates with two cars.
- a major advantage of this embodiment is that the above-mentioned loss times, which arise, for example, when feeding or loading the trolley with the items to be sawn and / or by aligning the items to be sawn on the item support of the trolley, are reduced or minimized can be. This makes it possible to increase the productive sawing time of the sawing system and thus the throughput of producible sawing products. This leads to an economically optimized operation of the sawing system.
- saw is understood in the present case in particular to be a motorized band saw, a motorized circular saw or a motorized chop saw, with other types of saw also being possible.
- the first and second carriages can each be moved back and forth separately from one another on the rail guide. This means that, for example, the first carriage can move back and forth on the rail guide, while the second carriage is (at the same time) and is being loaded with material to be sawn.
- the first car As soon as the first car has to be reloaded after the end or interruption of the sawing process or a realignment or manipulation is to take place on the first item to be sawn, it can move into its loading and manipulation position and the second car can go to the saw, to saw the newly fed or realigned second material to be sawn.
- the first and second carriages allow alternate sawing of either the first or the second item to be sawn with short “dead times”. In this way, the effective processing time of the material to be sawn can be increased compared to known systems.
- rail guide is understood here to mean any type of guide rail through which a guided sliding or moving of a carriage can be ensured.
- the rail guide can advantageously be made in the form of known rails.
- longitudinal direction is understood to mean a direction in which the rail guide is laid along its length.
- the rail guide runs preferably in a straight line, starting from a start position defined upstream of the saw to an end position defined downstream of the saw along the longitudinal direction.
- the first and the second car each have their own car drive.
- the two carriages can be moved back and forth or upstream and downstream along the longitudinal direction.
- the wording "that the saw is arranged on the rail guide” expresses that the saw is arranged laterally next to the rail guide, that is, preferably in the direction of a track width of the rail guide, next to it.
- the phrase "drive past” means that the item to be sawn is driven through the saw blade with a predefined protrusion (which is defined transversely to the longitudinal direction) so that the product to be sawn can be cut off / sawed off.
- the thickness of the saw product to be sawed off is defined on the basis of this overhang, taking into account a loss width that is defined by the thickness of the saw blade.
- the first sawmill supply is set up to transfer the first sawmill to the first support in a transverse direction that is defined transversely to the longitudinal direction. Furthermore, it is preferred that the second sawmill supply is set up to transfer the second sawmill in the transverse direction, which is defined transversely to the longitudinal direction, to the second support.
- transversely is not necessarily understood to be perpendicular or orthogonal, but rather any feed at an angle other than 0 °.
- the supply is essentially perpendicular or orthogonal (i.e. at an angle of 90 ° ⁇ 10%) to the longitudinal direction.
- the sawing system viewed in the longitudinal direction, defines a first feed area, a work area adjoining the first feed area and a second feed area adjoining the work area.
- the first saw feed is arranged in the first feed area, which is the saw arranged essentially centrally in the work area and the second sawmill feed is arranged in the second feed area.
- the first feed area (or the first loading and manipulation area) of the first car is located at the beginning of the rail guide (upstream).
- the work area is located in a central area of the rail guide, which, viewed in the longitudinal direction, extends on both sides of the saw.
- the saw is preferably arranged essentially centrally ( ⁇ 10%) in the work area.
- the material to be sawn is processed by means of the saw.
- the saw products are generated and removed in the work area.
- the second feed area (or the second loading and manipulation area) of the second carriage is arranged at the downstream end of the rail guide. In each of the two feed areas, the respective wagon is loaded with the material to be sawn and, preferably, the material to be sawn is aligned on the respective material to be sawed.
- first and / or the second supply area adjoin the work area, but preferably do not overlap with it.
- the first The third and / or the second feed area preferably does not or only partially overlaps the work area.
- the first supply area is located upstream of the saw in the longitudinal direction and the second supply area is located downstream of the saw in the longitudinal direction.
- the work area extends longitudinally both upstream and downstream of the saw, whereas the first feed area is further upstream without overlapping with the work area and the second feed area is further downstream without overlapping with the work area.
- the sawing system also has a first discharge for items to be sawn and a second discharge for items to be sawn.
- the first and second saw product removal are set up to remove a saw product that has been created by sawing the first or the second saw product in the longitudinal direction.
- This embodiment has a further difference compared to the usual structure of a sawing system.
- saw products are produced both in the forward and backward movement of the carriage, saw products are produced both upstream and downstream of the band saw and are discharged as follows according to the current state of the art:
- the downstream of the band saw saw products are on a
- Conveyor technology removed in the longitudinal direction.
- the upstream saw products are transported by means of a further conveyor, which is arranged between the saw blade and a stand construction of the band saw (the band saw stand), through the band saw stand onto the conveyor system located downstream in the longitudinal direction and removed from it in the longitudinal direction.
- the upstream saw product After the upstream saw product has passed the band saw frame, it is removed by the same conveyor technology that is also used for downstream saw products.
- the downstream transport system is still occupied by a saw product that has occurred upstream (in front of the band saw frame), since this saw product has to cover a longer distance (through the band saw frame).
- the first saw product discharge is set up to discharge the saw product transversely to the longitudinal direction.
- the second saw product discharge is set up to discharge the saw product transversely to the longitudinal direction.
- first and second saw product discharge are arranged in the longitudinal direction upstream of the saw, the second shegegutabssel downstream of the saw. It is preferred that both the first saw product discharge and the second
- Sawn goods removal is located in the work area of the sawing system in order to avoid interaction with the first or second saw goods supply area.
- the saw has a band saw blade which, during sawing, defines a sawing direction which is oriented transversely to the longitudinal direction.
- the sawing direction denotes the direction of rotation of the band saw blade, around two preferably existing band saw rollers, between which the band saw blade is stretched, and around which the band saw blade is moved during sawing.
- the sawing direction is preferably parallel to an imaginary connecting line between the two centers of the band saw rollers.
- the band saw blade viewed in the longitudinal direction, has saw teeth on both sides.
- This double-sided saw toothing ensures in an efficient manner that sawing of the material to be sawn can take place when the first or second carriage moves from upstream to downstream as well as from downstream to upstream.
- a first cellar chute is arranged upstream of the saw. It is also preferred that a second cellar chute is arranged downstream of the saw.
- a first useful surface is generated on the material to be sawn in a downstream movement of the carriage.
- a section piece the so-called rind
- This rind must from the further removal pro- process can be discharged.
- the rind usually falls downstream of the saw and is ejected in the direction of waste wood disposal by moving the conveyor system (i.e. the roller conveyor or conveyor belt downstream of the saw) into an opening on the floor, the so-called cellar dump.
- the separated rind usually falls into this cellar chute immediately after it has been separated from the material to be sawn and can thus be ejected directly from the further production process.
- the first basement chute is set up, a
- the second cellar chute is set up to take up a rind that occurs when sawing the first and / or second items to be sawn.
- a conveyor is also arranged on the saw, which is directed to tilt an axis of rotation running parallel to the longitudinal axis.
- the conveyor is preferably arranged in an area between the saw blade and the saw stand. Furthermore, it is preferred that the first sawed material discharge is arranged upstream of the conveyor in direct connection with it. Furthermore, it is preferred that the second sawed material discharge is arranged downstream in direct connection to the conveyor. Through this constellation it is possible to have a smooth To ensure removal of the saw products both upstream and downstream of the saw.
- the conveyor can be tilted around the axis of rotation (in particular foldable upwards), unlike in the prior art, so that only part of the rind is removed when the rind is discharged upstream the first material to be sawn away (a conveyor system set up for this purpose) is moved transversely to the longitudinal direction in order to open the first cellar chute.
- first and second carriages are set up to be coupled to one another in order to be moved simultaneously on the rail guide in the coupled state.
- the coupling can be realized purely mechanically (for example via catch hooks) and / or (electro-magnetic and / or also virtually (through a control-technical coupling of the first and second carriage drive) / or the second sawmill can preferably be set up to transfer excessively long material to be sawn to the two coupled carriages.
- first and second carriages Due to the advantageous coupling of the first and second carriages, it is possible to use two smaller, lighter and therefore more dynamic carriages in terms of mobility, which advantageously each have their own drive, so that the processing of large-sized items to be sawn (for example long Round wood or long tree trunks) is possible. Due to the relatively low weight of the first and second carriages, it is possible to achieve high acceleration values, which are difficult to achieve with a longer and therefore heavier carriage, which is normally required for processing long logs. By coupling the two carriages, it is possible to unite the two stateurierlage with each other and thereby also the number of preferably available clamping brackets that are used to fix the sawed product on the sawed support, in particular for the Increase the processing of larger-sized items to be sawn. In this way, a high dynamic performance of the respective carriage can be guaranteed even when processing longer items to be sawn.
- the first and second carriages are moved essentially in an alternating sequence along the longitudinal direction in order to saw the first and / or the second material to be sawn.
- the items to be sawn are preferably carried out in an alternating sequence, i.e. while the first trolley is being loaded with the first item to be sawed or this is being positioned on the item to be sawed, the second item to be sawn is processed by moving back and forth because of the second trolley. If the processing of the second item to be sawn has been completed or if the sawing process has to be interrupted due to repositioning of the second item to be sawed on the item support and the loading of the first carriage and positioning of the first item to be sawn on the first item to be sawn, the processing of the first item to be sawn can be carried out as directly as possible Subsequent to the completion of the processing of the second item to be sawn.
