Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • boards or similar products are typically made from logs that have an essentially circular cross-section.
  • the boards in question are made from both an inner and an outer cross-sectional area of the log.
  • the log is sawn along its longitudinal axis using a sawing device, after which the boards are spatially bound and in the form of a sawn timber package.
  • the circular cross-section of the sawn log inevitably means that the boards obtained from the inner cross-section area have different dimensions than those boards that come from the outer cross-section area.
  • the boards in the sawn timber package that are obtained from the inner cross-section area are referred to as the main board.
  • the boards from the outer cross-section area are referred to as the side boards. Both the main board and the side boards can be single-stem or multi-stem.
  • main boards and the side boards In order for the main boards and the side boards to be used for different purposes depending on their dimensions, they must be separated from each other.
  • the separation process required for this is typically carried out efficiently during the conveying movement of the sawn timber package, using a device of the type mentioned above.
  • Such a previously known device is known from AT 17009 U1 and is used to separate a sawn timber package into main and side goods.
  • the device comprises a wedge serving as a separating means, which is positioned in such a way that it moves into a sawing gap between the main and side panels. This causes the side panels to be deflected in a direction away from the main panel.
  • a device in which a conical roller is used as a separating means, which is mounted so that it can rotate around a horizontal axis.
  • the roller penetrates a vertically running saw gap in the sawn timber package with a circumferential separating edge.
  • the boards of the sawn timber package are deflected sideways in relation to the conveying direction of the sawn timber package and are thus spatially separated.
  • additional storage and transport means must be provided in order to be able to transport the separated boards of the sawn timber package further.
  • the invention is based on the object of proposing a device with an improved separating means in order to increase the operational reliability of the device and to ensure a permanently high level of productivity.
  • the device should have a simple technical structure in order to be highly resistant to faults.
  • the device according to the invention serves to separate a sawn timber package obtained from a log by a cut into main goods and side goods during its longitudinal transport.
  • the device comprises at least one separating means which is positioned in such a way that it engages in a saw gap between the single or multi-stemmed main goods and the side goods during a feed movement of the sawn timber package and deflects the side goods in a direction away from the main goods.
  • the side goods are arranged above and/or below the main product during the longitudinal transport of the sawn timber package.
  • At least two rotatably mounted conical rollers are provided as separating means, each of which has a circumferential separating edge formed by two rotating surfaces enclosing an acute angle.
  • the two conical rollers are arranged on either side of the sawn timber package and are oriented in such a way that their respective separating edges engage laterally in the horizontal saw gap and roll along the main product with their first rotating surface, while they push the side products away from the main product with their second rotating surface.
  • the invention is based on the finding that the conical rollers, due to their geometry and their rotating bearings, enable reliable separation of the main and side goods while the sawn timber package is transported further in its feed movement. If the sawn timber package hits the conical rollers during its feed movement, the separating edges of the conical rollers penetrate into the saw gap. This allows the conical rollers to be set in a rotating movement so that the main goods can roll along the conical rollers and the sawn timber package is only slightly slowed down in its feed movement. This prevents jamming between the conical rollers designed as separating means and the sawn timber package. At the same time, the acute angle between the two rotating surfaces of the respective conical rollers ensures that the side goods are continuously pushed away from the main goods as the sawn timber package continues to move.
  • the arrangement of two conical rollers according to the invention makes it possible to separate a package of sawn timber, which was produced by horizontal cutting, in which the individual main and side boards are transported stacked on top of each other, into main and side boards.
  • the invention makes it possible to separate the bottom side board(s) on which the main board(s) rest from the latter and to transport them further via a separate transport channel.
  • the main goods can rest on the conical rollers, while the side goods are dropped on the second rotating surfaces of the conical rollers and preferably with the aid of gravity below the main goods or are conveyed further in the transport direction via a separate guide channel below the main goods.
  • the conical rollers therefore serve simultaneously as bearing elements for the main goods boards and as a separating means for the side goods board(s).
  • the side product can slide off the main product at the separating edge and, in accordance with the acute angle formed by the rotation surfaces, at the respective second rotation surface of the conical rollers and against gravity.
  • the device can comprise additional guide means, in particular cylindrical rollers, in order to receive the side product and convey it further.
  • the device preferably comprises at least four conical rollers.
  • a first pair of the four conical rollers is arranged on both sides of the sawn timber package and is oriented such that the conical rollers of the first pair engage laterally with their respective separating edges in a first sawing gap which is formed between the main product and a side product resting on the main product.
  • a second pair of the four conical rollers is arranged on both sides of the sawn timber package and is oriented such that the conical rollers of the second pair engage laterally with their respective separating edges in a second sawing gap which is formed between the main product and a side product arranged below the main product.
  • the invention is not limited to a specific geometry of the respective conical rollers, so that basically different rotating bodies can be used. It is only essential that the conical rollers each have two Have rotation surfaces which enclose an acute angle at their common separating edge, which can be, for example, 45°.
  • the conical rollers can be made of metal, plastic, rubber or a combination of the materials mentioned.
  • the conical rollers preferably each have a bore for receiving one or more bearing means, in particular roller bearings.
  • the conical rollers can be mounted in a structurally simple manner so that they can rotate and are stationary or displaceable on a machine frame of the device according to the invention.
  • a stationary storage is advantageous if the device according to the invention is used to separate sawn timber packages with uniform dimensions and the position of the saw gap between the main product and the side product does not vary significantly between different sawn timber packages.
  • An adjustable storage of the conical rollers is advantageous if the positions of their separating edges are to be adjusted depending on varying sawn timber package dimensions and saw gap positions.
  • At least the second rotation surface of the conical rollers has a convex curvature in the profile. This allows the pressure distribution in the corresponding conical roller to be optimized during the engagement of its separating edge in the saw gap. This relieves the separating edge in particular during the separating process.
  • the conical rollers each have a lateral surface and a flat base surface, wherein the respective lateral surface forms the first rotation surface and the respective base surface forms the second rotation surface.
  • the conical rollers are mounted in such a way that their respective outer surfaces roll on the main material, while the side material is deflected on the side of the respective base surfaces.
  • the orientation of the conical rollers and their axis of rotation is not important here. The only important thing is that the separating edges of the conical rollers engage in the saw gap of the sawn timber package.
  • the conical rollers are each mounted so as to be rotatable about a rotation axis and are oriented in such a way that the respective rotation axis encloses an acute angle of inclination with a saw gap plane formed by the saw gap in an inclination plane which is directed orthogonally to the feed movement, and the main product rests at least partially on the respective separating edge and preferably on the respective lateral surface.
  • the angle of inclination is smaller than the acute angle enclosed by the lateral surface and the base surface.
  • the angle of inclination essentially corresponds to the acute angle enclosed by the outer surface and the base surface.
  • the conical rollers are mounted in such a way that their outer surfaces each roll along a linear contact on the main material. This does result in increased friction compared to the embodiment in which the main material rests on the separating edges.
  • the separating edge can be mechanically relieved because the weight of the main material is better distributed over the surfaces of the conical rollers.
  • the respective rotation axis in the saw gap plane forms an acute angle with the inclination plane.
  • the base surfaces of the conical rollers each point against the feed movement of the sawn timber package and each serve as a sliding plane for the sideboard to be rejected.
  • the above-described advantageous development further improves the reliability of the separation process.
  • the inclined position of the conical rollers which has the acute angle of attack described above, (also: lintel)
  • the base surface faces the opposite direction to the feed movement of the sawn timber package in such a way that the side products can be guided from the main product in a ramp-like manner over the flat base surfaces of the conical rollers.
  • the sliding planes formed in this way allow a geometrically defined guidance of the side products from the main product.
  • the conical rollers each also have a lateral surface and a flat base surface, but the base surfaces each form the first rotation surface and the lateral surfaces each form the second rotation surface.
  • the conical rollers are mounted in such a way that the base surfaces roll on the main product, while the lateral surfaces serve to deflect the side products.
  • the conical rollers are preferably mounted in such a way that the base surfaces each run essentially parallel to the sawing gap plane formed by the sawing gap.
  • the rotation axes of the conical rollers each run orthogonally to the sawing gap plane mentioned above. If the separating edges penetrate into the sawing gap of the sawn timber package with such an arrangement, the main product lies fully against the base surfaces, while the side products are deflected on the side of the lateral surfaces.
  • the conical rollers whose base surfaces each form the first rotation surfaces and whose lateral surfaces each form the second rotation surfaces, are inclined in such a way that their rotation axes each enclose an acute tilt angle with the saw gap plane in a tilting plane which is directed parallel to the feed movement and orthogonal to the saw gap plane.
  • the base surfaces are facing in the feed direction.
  • the conical rollers are tilted with their respective rotation axes against the feed direction, so that the base surfaces of the conical rollers do not lie completely on the main material during the separation process.
  • the respective base surfaces and the saw gap plane formed by the saw gap also enclose the tilt angle, which is open in the direction of the feed movement. This reduces the friction between the respective base surface and the main material.
  • the conical rollers each have a drive which is designed to set the conical rollers in a rotational movement about their respective axis of rotation.
  • the conical rollers have a tangential speed in the area of the separating edge engaging in the saw gap, which is directed at least partially in or against the feed movement.
  • the development described above is based on the knowledge that the rotational movements of the conical rollers compared to the feed movement improve the reliability of the separation process. Because the two conical rollers engage in the saw gap of the sawn timber package on opposite sides and are set in an opposite rotational movement, the forces acting on the sides of the sawn timber package are increased as a result of friction. This means that the main material and the side material are better centered during the separation process.
  • the drive also ensures that the rotary bearings of the conical rollers do not become dirty over time and stiff due to dust and chips that inevitably occur during a sawing process, as the conical rollers are constantly moving.
  • the above-mentioned drive can easily comprise an electric machine. Furthermore, a gear and/or a clutch can be provided, in particular in order to be able to convert the drive movement of the electric machine.
  • the drive is preferably designed to be controllable and is connected by signaling to an electric control unit of the device.
  • the device has a centering unit which is arranged in front of the conical rollers in relation to the feed direction.
  • the centering unit is designed to align the sawn timber package in relation to the separating means during the feed movement.
  • the centering unit can comprise one or more cylinder rollers in a structurally simple manner, by means of which the sawn timber package is guided. These rollers are preferably driven and support the feed movement of the sawn timber package.
  • a cylinder roller is mounted so that it can be adjusted that their displacement causes a corresponding displacement of the sawn timber package.
  • such a centering unit comprises at least one adjustment means, which is designed in a simple manner as an electrical or hydraulic linear actuator.
  • the centering unit can be connected to the control unit of the device by means of signals, wherein the adjustment can be carried out depending on an expected sawn timber dimension and/or an expected position of the saw gap in the sawn timber package.
  • a sensor in particular an optical sensor, is designed to measure the sawn timber dimensions and/or a saw gap position within the sawn timber package.
  • a sensor is preferably arranged upstream of the centering unit in relation to the feed movement of the sawn timber package and is designed as an optical sensor, in particular as a camera, by means of which the sawn timber package is detected in a front area.
  • the optical sensor is designed with an integrated evaluation unit or the control unit is designed to determine the position of the saw gap in the sawn timber package using a digital image processing method.
  • the control unit causes the centering unit to be adjusted depending on the measurement signal in order to adapt the sawn timber package with the saw gap to the position of the separating edge.
  • the device comprises a positioning device which is designed to displace and/or rotate the conical rollers in relation to at least one adjustment axis relative to the sawn timber package.
  • the device comprises a positioning device which is designed to position the conical rollers in a plane orthogonal to the feed movement depending on a position of the saw gap in the sawn timber package and to adapt the positions of the separating edges of the conical rollers to the position of the saw gap.
  • the positioning device can comprise at least one electric or hydraulic linear actuator, which is connected to the electrical control unit by means of signals.
  • the linear actuator serves to displace the conical rollers along a linear path.
  • the displacement can be carried out in any spatial direction and thus in or against the feed direction and/or transverse to it. It is also within the scope of the advantageous development that the positioning device is designed to adjust the inclination angle and/or the setting angle and/or the tilt angle of the respective conical roller before and/or during the separation process.
  • the positioning device makes it possible to dynamically feed the conical rollers during the separation process and thereby positively influence the separation process. This is advantageous because it can influence the movement path of the rejected side goods or the side goods can be lifted off the main goods.

  • the sawn timber package 2 comes from a tree trunk with an essentially circular cross-section.

  • the conical rollers 9 are arranged axially symmetrically to the sides of the sawn timber package 2 with respect to the feed direction 7. For better clarity, not all conical rollers 9 are provided with reference symbols.

  • the angle of inclination 15 is selected depending on the geometry of the conical rollers 9 and corresponds to the acute angle between the base surface and the outer surface 12 of the conical rollers 9. This means that the main material 3 rests on or against a profile line of the outer surfaces 12 during the separation process and rolls over these on the conical rollers 9. In an alternative embodiment, the angle of inclination can be set smaller so that the main material 3 rolls over a point contact on the separating edges 13 of the conical rollers 9.
