Definitions
- the invention relates to a device for eccentric cutting of veneers from a block of wood according to the preamble of claim 1.
- Such devices are used to cut thin sheets, also called veneers, from a block of wood.
- the process is also called knives.
- the wooden block is clamped on a support surface of a beam construction formed by a flat outer surface. This is rotatably supported about its horizontal longitudinal axis, so that with each rotation a veneer is cut off with a knife mounted parallel to the longitudinal axis and movable towards the beam construction.
- Such devices are also known as Staylog knife machines.
- a tangentially rotating veneer knife machine is known from EP 584 268 B1, in which four wooden blocks can be clamped on a beam construction (Fiitch table).
- a beam construction Fiitch table
- docking bodies with oval heads are arranged, which are rotatably driven in the Fiitch table and releasably engage in grooves that are worked into the wooden blocks.
- DE 30 26 162 C2 describes a generic Staylog knife machine, in which claws for clamping a wooden block engage in grooves in the base of the wooden block.
- a clamping device with claws that engage laterally in the wooden block is arranged. The claws can be swiveled away when the wooden block is cut to a certain size.
- the problem with the known Staylog knife machines is that the remaining block - that is the wooden block that remains after the knife - has to be removed from the beam construction by hand. As a result, the set-up time for removing the remaining block and clamping the new wooden block is relatively long.
- the object of the invention is to improve a Staylog knife machine so that the set-up time for the removal of the remaining block and the clamping of the new wooden block is shortened.
- Wood blocks is arranged, practically no time is consumed for its removal. The operating personnel does not have to take care of removing and removing the remaining block and is thus relieved.
- the time saved by the device according to the invention is 20 to 30 seconds.
- an average cycle time time from the end of the measurement of a first block of wood to the end of the measurement of the following block of wood
- the relative time saving and thus the increase in productivity by the invention is around 7 to 10%.
- Conveyor chains according to claim 2 are simple and robust.
- FIG. 1 shows a side view of a Staylog veneer knife machine according to the invention, partially cut
- Figure 2 shows part of a Staylog bar arrangement as a detail from Figure 1 and
- Figure 3 is a view of the Staylog bar arrangement seen from a tool slide, partially in section.
- a veneer knife machine consists of a base frame 1, on which a tool slide 2 with a knife holder 3 is fastened on one side, the right side in the figure, and a Staylog bar arrangement 4 on the other side, left side in the figure are.
- the tool slide 2 is mounted on two parallel rails 6 in a horizontal plane so that it can move back and forth, as symbolized by the arrow 5.
- the tool slide 2 with guide elements 7, which are fastened to a machine frame 8, is guided on the rails 6 with minimal play and secured against rotation and can be driven by hydraulic cylinders 14.
- the knife carrier 3 On the top of the machine frame 8, the knife carrier 3 is fastened with a knife 10 in such a way that it can be moved in the direction of the arrow 9 and is rotatably mounted about an axis in the region of a downward cutting edge of the knife 10.
- the knife 10 and thus its cutting edge extend at right angles to the direction of movement of the tool slide 2.
- the knife 10 is arranged in the (on the left in FIG. 1) side of the knife carrier 3 which is opposite the Staylog bar arrangement 4.
- the rotatability and displacement of the knife carrier 3 relative to the machine frame 8, which is necessary for adjusting its position relative to a pressure beam 11 described below, is ensured by various hydraulic cylinders.
- the pressure beam 11 is fastened to the machine frame 8 below and parallel to the knife 10. Pressure bar 11 and knife 10 are set in operation so that a short distance is maintained between the two.
- the Staylog beam arrangement 4 is fastened on the base frame 1 in such a way that the horizontal longitudinal axis of its beam construction 12 runs at right angles to the rails 6.
- the beam structure 12 is rotatably mounted between two housing walls 13 and connected to a drive, not shown.
- a wooden block 16 can be clamped on a support surface 15 of the beam structure 12 formed by a flat lateral surface by means of clamping means, here clamping claws 17 and holding claws 19.
- the clamping claws 17 protrude in two rows parallel to the longitudinal axis of the beam structure 12 from the support surface 15, the rows of the clamping claws 17 being movable towards and away from one another by means of suitable drives (not shown).
- the clamping claws 17 engage in grooves 18, which are embedded in a base of the wooden block 16. The distances between the clamping claws 17 and the grooves 18 are matched to one another.
- the holding claws 19 are fastened on a rotatably mounted shaft 20 on each side on both longitudinal sides of the beam structure 12, which adjoin the bearing surface 15, in such a way that they laterally about an axis parallel to the longitudinal axis of the beam structure 12 in a working position the wooden block 16 can be pressed or moved into a rest position on the sides of the beam structure 12.
- Each shaft 20 is connected to a rotary drive, not shown.
- the holding claws 19 are not shown in Figure 3 for reasons of clarity.
- the veneer knife machine corresponds to the state of the art.
- the means for repelling can be seen more clearly from FIGS. 2 and 3 and in this example comprise four hydraulically operated pistons 21. These are even spaced in the beam structure 12 so that the outer ends of the pistons 21 face openings in the support surface 15, the longitudinal axes of the pistons 21 being approximately perpendicular to the support surface 15. In the rest position, the ends of the pistons 21 are within the outer limit of the beam structure 12; in the working position, the pistons 21 pierce the associated openings in the support surface 15 of the beam structure 12.
- the device for automatic removal comprises three parallel, endless conveyor chains 22, a drive with a motor 23 and deflection rollers 24.
- Each conveyor chain 22 is assigned four deflection rollers 24, one of which is designed as a tension roller and one as a drive roller.
- the deflection rollers 24 are rotatably supported in the base frame 1 in two approximately horizontal planes, the drive rollers being fastened on a shaft 25 which can be driven by the motor 23 via a gear.
- the deflection rollers 24 are arranged such that their axes of rotation run parallel to the longitudinal axis of the beam structure 12 and that the enveloping surfaces are flat and form a parallelepiped.
- deflection rollers 24 which are located in a vertical plane running parallel to the longitudinal axis of the beam construction 12, are spaced from this longitudinal axis in the direction of the tool slide 2.
- the other six deflection rollers 24 are arranged on the end of the base frame 1 opposite the tool slide 2.
- Each conveyor chain 22 is guided over four of the deflection rollers 24 arranged in a vertical plane perpendicular to the longitudinal axis of the beam construction 12 in such a way that a rectangle with round corners is formed.
- Each conveyor chain 22 is guided under the floor in a U-profile 26 between the upper deflection rollers 24, that is to say its upper limit is below a largely flat and horizontal surface formed by plates on the base frame 1.
- the conveyor chains 22 are evenly spaced, the middle one being arranged approximately centrally under the beam assembly 12.
- a carrier 27 is fastened to each conveyor chain 22 in such a way that it points radially outwards with respect to the endless conveyor chain 22 and has the same relative position with respect to the drive axis 25 for each conveyor chain 22.
- the length of the driver 27 is approximately two to three times the height of the U-profile 26.
- the entire knife machine, including the means for repelling the remaining block and the device for automatic removal, are connected to a central controller - for example a PLC (programmable logic controller) or a computer - which determines the work processes of the knife machine.
- the tool slide 2 In operation, which takes place with the exception of the pushing off of the wooden block 16 after the end of the knife operation and the automatic removal of the pushed off wooden block 16 as is known from the prior art, the tool slide 2 is initially at the maximum possible distance from the stay log bar arrangement 4 - the so-called Rest position - retracted. A wooden block 16 is clamped on the beam structure 12 with the aid of the clamping claws 17 and optionally the holding claws 19. The tool slide 2 is moved into a working position so that a small horizontal gap remains between the outermost rotation circle of the wooden block 16 and the cutting edge of the knife 10. The drive for the beam construction 12 is switched on, so that it is rotated with the clamped wooden block 16 about its longitudinal axis counterclockwise according to arrow 28 in FIG. 1.
- the cut fumier leaves are automatically removed.
- the tool slide 2 moves a defined distance in the direction of the Staylog beam arrangement 4, this distance corresponding to the nominal thickness of the veneer sheet. This process is repeated until so many veneer sheets have been cut from the wooden block 16 that only a minimal remnant of the wooden block 16 (remaining block) remains, which cannot be cut further because the knife 10 would protrude into the beam structure.
- the veneer knife machine stops automatically. During the cutting - that is, without interrupting the process - the holding claws 19 are possibly moved into their rest position before the cutting edge of the knife 10 is moved into the area in which it could come into contact with the holding claws 19.
- the beam structure 12 is rotated into a six o'clock position, that is to say the wood block 16 is located approximately perpendicularly under the axis of the beam structure 12.
- the clamping claws 17 are opened.
- the pistons 21 are extended, pushing the block of wood 16 off the support surface 15 in this way.
- the wooden block 16 falls on the flat and horizontal surface on the base frame 1 and remains there for the time being.
- the bar construction 12 is then rotated into a twelve o'clock position, that is to say the support surface 15 is approximately perpendicular to the axis of the bar construction 12. During these operations, the tool slide 2 is simultaneously moved back into its rest position.
- a new block of wood 16 is clamped by the operating personnel and the cutting process begins again.
- the drive for the conveyor chains 22 is automatically switched on by the control.
- the drivers 27 capture the block of wood 16 and transport it from the area of the knife machine, for example to a further transport device.
- the minimum transport distance through the conveyor chain 22 is specified, which is required for the safe removal of the remaining block. Depending on the local conditions, it may make sense to extend the transport route beyond the end of the base frame 1 to a further transport system.
- the means for repelling the wooden block 16 can alternatively to the hydraulically operated pistons 21 e.g. be designed as a magnetically or pneumatically operated plunger or as a rocker.
- the rocker is an articulated construction that has the shape of a parallelogram in a basic position, with one longest side being articulated; by moving the opposite short side in the direction of its longitudinal axis, the longest side is tilted around the articulated attachment.
- the device for automatic removal can consist of at least one hydraulic cylinder, the working direction of which in the plane of the base frame 1 is perpendicular to the longitudinal axis of the beam structure and a slide is attached to the outer piston end of the latter.
- at least one roller conveyor is arranged, which is either drivable or designed as an inclined plane descending in the direction of removal.
