Description

The invention relates to a finishing station for a device for producing wooden, bar-like or plate-like structural elements assembled at the front via finger joints, as well as a milling station for such a finishing station, and a device with such a finishing station.

State of the art

When processing wood, which is usually in the form of sticks or plates, the wood fed into a device must regularly have defective areas with unforeseeable lengths cut off in a dressing station at the input, which produces wood with the same cross-section and usually different lengths. Finger joints are milled into the two ends of the wooden rods, into which glue is applied so that the milled wooden rods can be joined and pressed together with their ends in a pressing device downstream of the dressing station to form a continuous wooden strand. Wooden rods of the desired length are then cut off at one end of the wooden strand, while further wooden rods with finger-jointed ends are added to the opposite end. The finger-jointed wooden rods are pressed together to form a continuous wooden strand. On the one hand, the wood material represents a large proportion of the total price for products made from cut finger-jointed wood, such as squared timber, glued laminated timber or laminated beams. On the other hand, the throughput of wood through the device determines the efficiency of the device, with the necessary pressing of the wood being a significant time factor, whereby strict specifications must be met with regard to strength and quality.

From the AT 505 211 A2 A device is known for producing pieces of wood joined at the end using finger joints. The device consists of two milling stations, a pressing station for joining and pressing the pieces of wood, and means for feeding the pieces of wood to the pressing station. The feeding means transfer the pieces of wood to the first milling station and the second milling station. In addition, the feeding means transfer the pieces of wood with finger joints on both sides to the pressing station. The speed at which the individual feeding means drive the pieces of wood can be adjusted independently of the speed at which the other feeding means drive the pieces of wood.

From the DE 20 2020 105 783 U1 A pressing device for a device for producing wood strands from glued finger-jointed wood is known. The device comprises an input area through which the wood can be fed and in which a feed unit is arranged for moving the wood in a feed direction. The device also comprises successive clamping and pressing units which are intended for clamping and pressing a wood strand consisting of at least two pieces of wood provided with finger-jointed profiles on the front side and glued. At least one of the clamping and pressing units is arranged so that it can be moved in the feed direction and in the opposite direction. The input area comprises two clamping and pressing units, which are followed by the feed unit in the feed direction.

From the DE 20 54 807 A is an end processing machine for one- and two-sided processing of workpieces with any cross-section. A braking device arranged above the conveyor belt is described, which presses and holds the workpieces against the carriers and supports of the conveyor belt in order to generate the necessary holding force for the processing units. The processing units are designed as a milling spindle, a pre-slotting spindle or a cross-cut saw. The processing units are arranged one behind the other, and the end processing machine also includes two milling spindles, which are arranged on opposite sides of the conveyor belt. The milling spindles each mill one end face of a workpiece.

From the US 3 802 986 A A finishing line is known which comprises a conveyor line and a profiling station. The profiling station comprises motor-driven rotating knives which process the end of the wood during transport in order to provide the end with a groove and/or a tongue. Immediately downstream of the profiling station there is an applicator which applies a coating with an adhesive component to the end of the piece of wood which passes through it.

From the DE 30 46 319 A1 A device for joining strip sections of different lengths at the end is known. The device comprises an endless conveyor belt with carriers arranged at a distance from one another transversely to the conveying direction. Finger joint milling and gluing devices are arranged offset from one another on both sides of the conveyor belt.

At least one cross conveyor is arranged above the conveyor belt, which conveys the strip sections from one side of the conveyor belt to the opposite side.

From the US 5 617 910 A a device for joining blocks is known. The blocks to be joined are fed to a finger jointing machine on an intermittently operating feed conveyor, on which they are lined up side by side with one end resting against a stop. The blocks are then conveyed to a first milling machine, where a finger joint is milled into one end. As the cleat conveyor moves the blocks further through the finger jointing machine, the unmilled ends of the blocks are picked up by a shifting conveyor, which pushes the blocks across the conveyor belt. The other end is then machined by a second milling machine.

From the EP 3 090 849 A1 A production line for elongated wooden workpieces is known, which comprises an input chain conveyor, a turning and feeding device, two processing units, a main conveyor chain, a diagonal chain conveyor, two auxiliary chain conveyors, an outlet rotor, an angle feed unit, an assembly unit, a continuous press and a saw. Processing takes place continuously and synchronously throughout the entire line. The elongated wooden workpieces clamped in the spring clamping devices move past a first processing device, which consists of a miter saw for aligning the front edges and profile cutters for milling the teeth into the aligned front surface. In this process, one wooden workpiece is processed on its front side in the processing device.

disclosure of the invention

The object of the invention is to create a dressing station that allows an improved throughput of milled wood.

A further object of the invention is to provide a device with improved throughput with such a dressing station.

The objects are achieved by the features of the independent claims. Favorable embodiments and advantages of the invention emerge from the further claims, the description and the drawing.

The features listed individually in the patent claims can be combined with one another in a technologically meaningful manner and can be supplemented by explanatory facts from the description and by details from the figures, whereby further embodiments of the invention are shown.

The invention is based on a dressing station for a device for producing wooden, bar-like or plate-like structural elements assembled at the end via finger joints. The dressing station comprises at least one first and at least one second milling station, which are each spaced apart from one another in a feed direction and are designed to create finger joint profiles on the end faces of individual pieces of wood to be joined. The dressing station also comprises means for feeding the individual pieces of wood to be processed in a feed direction at least to the first of the two milling stations, transversely to the feed direction between the at least one first and at least one second milling station and away from the at least one second milling station.

It is proposed that each of the milling stations is prepared in order to form synchronously and simultaneously, at the respective milling station, front-face finger joint profiles on at least two individual pieces of wood aligned parallel to each other with their longitudinal extension.

The milling stations each have at least one clamping unit with which the individual pieces of wood can be separately fixed in front of the respective milling station.

In front of each of the milling stations, there are stop devices on which the pieces of wood are placed with their longitudinal edges in the feed direction of the cross conveyor before milling and the front edge of each piece of wood is aligned with a stop edge at the respective milling station so that the longitudinal edge and the front edge of the pieces of wood are at a well-defined angle to each other. It is advantageous to process several types of wood simultaneously and synchronously at a single milling station.

The pieces of wood can be held in position on the cutter sets during the milling process. This allows tolerances in the pieces of wood to be compensated, which saves the need to pre-plane the pieces of wood. The stop edge, on which the long side of the piece of wood is aligned, serves as a zero line for the alignment of the pieces of wood, just as a stop edge for the front side of the piece of wood serves as a zero line for the front side. This stop edge can advantageously be a table side of the conveyor between the milling stations in the dressing station.

The individual pieces of wood are aligned with their side edges parallel to a defined stop edge, and are therefore advantageously also aligned parallel to one another. Furthermore, the front edge of each piece of wood is aligned with a stop edge at the milling station, so that the long edge and the front edge are at a well-defined angle to one another. The front edge is advantageously aligned perpendicular to the long edge. When the pieces of wood are later pressed together to form a strand of wood, the individual pieces of wood can be joined and pressed together cleanly and with little loss. In principle, an angle between the front edge and the long edge that deviates from a right angle is also possible, so that two individual pieces of wood that are to be joined together have at least one front side that is inclined complementarily to the long side and are therefore easy to press together.

The parallel processing of individual pieces of wood in the preparation station allows for precise alignment of the side edges of each individual piece of wood to one another and an exact and reproducible setting of the angle between the respective front side and long side. This can reduce waste and improve the pressing result in a subsequent pressing station.

Advantageously, the throughput of the trimming station can be at least doubled when at least two individual pieces of wood are milled simultaneously at each milling station. Advantageously, the trimming station can be designed as a cycle chain system that processes pieces of wood in set work cycles. Optionally, the trimming station can also be designed without cycle chain operation.

According to a favorable design of the dressing station, a milling unit can be arranged in each of the at least first and at least second milling stations, with which at least two pieces of wood can be milled synchronously and simultaneously on the front side. Optionally, more than one milling unit can be provided in one or more of the milling stations.

The milling unit can be designed in such a way that a milling cutter set of the milling unit is provided with a width that is at least twice the width of the pieces of wood that are being milled in the milling station. Milling units are usually designed for certain maximum widths of individual pieces of wood that are to be milled. Such an arrangement can advantageously be widened accordingly. Additionally or alternatively, a milling unit can have several milling cutter sets that are designed for maximum widths of individual pieces of wood, with the milling cutter sets processing the corresponding pieces of wood synchronously. Furthermore, the milling unit can have several milling cutter sets that are provided with a width that is at least twice the width of the pieces of wood.

According to a favorable design of the dressing station, at least one of the milling units can have at least two milling cutter sets with which at least two pieces of wood can be milled synchronously and at the same time on the front side. The milling cutter sets can advantageously be moved synchronously for milling, for example from top to bottom or vice versa.

The wood can be elongated elements such as slats, boards, planks, squared timbers or the like.

According to a favorable design of the dressing station, at least one of the milling units can have a common drive for at least two milling cutter sets of the respective milling unit. The milling cutter sets can advantageously be moved synchronously by means of a common drive or feed, for example a common shaft or the like.

According to a favorable design of the dressing station, a device for applying glue to at least one of the two milled finger joint profiles of the two pieces of wood can be provided on or adjacent to the at least first and/or at least second milling station. A stable and permanent adhesive bond can advantageously be achieved during a subsequent pressing process of the pieces of wood.

According to a further aspect of the invention, a milling station is proposed for a dressing station, with a milling unit that is prepared to form front-side finger joint profiles synchronously on at least two pieces of wood that are aligned parallel to one another with their longitudinal extension. The pieces of wood are aligned parallel to one another in particular with their side edges.

The milling stations each have at least one clamping unit with which the individual pieces of wood can be separately fixed in front of the respective milling station.

In front of each of the milling stations, there are stop devices on which the pieces of wood are placed with their longitudinal edges in the feed direction of the cross conveyor before milling and the front edge of each piece of wood is aligned with a stop edge at the respective milling station so that the longitudinal edge and the front edge of the pieces of wood are at a well-defined angle to each other.

The pieces of wood can be held in position on the cutter sets during the milling process. This allows tolerances in the pieces of wood to be compensated, which saves the need to pre-plane the pieces of wood. The stop edge, on which the long side of the piece of wood is aligned, serves as a zero line for the alignment of the pieces of wood, just as a stop edge for the front side of the piece of wood serves as a zero line for the front side. This stop edge can advantageously be a table side of the conveyor between the milling stations in the dressing station.

The milling station advantageously allows an increased throughput of wood in a dressing station.

According to a further aspect of the invention, a device is proposed for producing rod- or plate-like components made of wood, which are joined together at the end by finger joints. The device has a dressing station with at least one first and at least one second milling station, which are spaced apart from one another in a feed direction and are set up to create finger joint profiles on the end of individual pieces of wood to be connected at both ends. The device has a pressing station designed for joining and pressing the individual pieces of wood provided with finger joint profiles on the end. The device also has means for feeding the individual pieces of wood to be processed, starting from an input side via the dressing station to the pressing station. The at least first and the at least second milling station are each set up to simultaneously form finger joint profiles on the end of at least two individual pieces of wood, whose lengths are aligned parallel to one another, at the respective milling station.

The milling stations each have at least one clamping unit with which the individual pieces of wood can be separately fixed in front of the respective milling station.

In front of each of the milling stations, there are stop devices on which the pieces of wood are placed with their longitudinal edges in the feed direction of the cross conveyor before milling and the front edge of each piece of wood is aligned with a stop edge at the respective milling station so that the longitudinal edge and the front edge of the pieces of wood are at a well-defined angle to each other.

The pieces of wood can be held in position on the cutter sets during the milling process. This allows tolerances in the pieces of wood to be compensated, which saves the need to pre-plane the pieces of wood. The stop edge, on which the long side of the piece of wood is aligned, serves as a zero line for the alignment of the pieces of wood, just as a stop edge for the front side of the piece of wood serves as a zero line for the front side. This stop edge can advantageously be a table side of the conveyor between the milling stations in the dressing station.

The pieces of wood are aligned parallel to each other, especially with their side edges.

Advantageously, the throughput through the device can be at least doubled by the increased throughput through the dressing station. Advantageously, the dressing station can be designed as a cycle chain system that processes individual pieces of wood in set work cycles. A cross-cut saw can be provided on the input side, which cuts the pieces of wood at defective points. A storage area is expediently provided between the cross-cut saw and the first milling station in order to keep sufficient pieces of wood ready for an increased throughput in the dressing station. The storage area can be designed, for example, as a cross conveyor for pieces of wood.

According to a favorable embodiment of the device, a milling unit can be arranged in each of the at least first and at least second milling stations, with which at least two pieces of wood can be milled synchronously on the front side. The milling unit can be designed in such a way that a set of milling cutters of the milling unit is provided with a width which corresponds to at least twice the width of the pieces of wood that are being trimmed in the trimming station.

This means that at least two types of wood can be processed with one cutter set of the milling unit. Alternatively, the milling unit can have at least two cutter sets.

Milling units are usually designed for specific maximum widths of individual pieces of wood that are to be milled. Such an arrangement can advantageously be widened accordingly.

According to a favorable embodiment of the device, at least one of the milling units can have at least two milling cutter sets with which at least two pieces of wood arranged parallel to one another can be milled on the front side. The milling cutter sets can advantageously be moved synchronously.

According to a favorable embodiment of the device, at least one of the milling units can have a common drive for at least two milling cutter sets of the respective milling unit. The milling cutter sets can advantageously be moved synchronously by means of a common shaft.

For example, the milling unit can have a drivable pulley, from which a shaft end protrudes in the axial direction on each side, on each of which a milling cutter set is arranged. Such an annular disk can also be arranged on the side of a shaft and the milling cutter sets can be mounted on the shaft from one side, whereby the milling cutter sets can advantageously be spaced apart from one another by intermediate rings. The milling cutters can also be driven directly by a motor.

According to a favorable design of the device, at least the means for feeding the individual pieces of wood to be processed can be designed as a cycle chain system. The increased throughput of wood can be moved through the device to the pressing station at a suitable rate.

An advantageous pressing station is in the DE 202020105783 U1 and allows a particularly high throughput with high quality of the joint areas between the pieces of wood. Other types of pressing stations, for example with continuous conveying of the pieces of wood, are also conceivable.

In the figures, components of the same type or with the same effect are numbered with the same reference symbols. The figures show only examples and are not to be understood as limiting.

Before the invention is described in detail, it should be noted that it is not limited to the particular components of the device and the particular method steps, since these components and methods may vary. The terms used herein are intended only to describe a particular embodiment and are not used in a limiting sense. Moreover, when the singular or indefinite articles are used in the description or in the claims, this also refers to the plural of these elements, unless the overall context clearly indicates otherwise.

Directional terminology used below with terms such as "left", "right", "top", "bottom", "before", "behind", "after" and the like is intended only to facilitate understanding of the figures and is in no way intended to limit the scope of the invention. The components and elements shown, their design and use may vary in accordance with the considerations of a person skilled in the art and may be adapted to the respective applications.

Figure 1 shows a block diagram of an embodiment of a device 200 for producing wooden, rod- or plate-like components assembled at the end via finger joints according to an embodiment of the invention with a cross-cut saw 230, a trimming station 100 with two milling stations 110, 140 and a pressing station 240. Figure 2 shows the finishing station 100 in a top view in detail. The two figures are described together below.

The cross-cut saw 230 is used to cut off defective areas of individual pieces of wood, which are then fed to the trimming station 100. This produces pieces of wood 12, 14 of different lengths, depending on the location of a defect. In the milling stations 110, 140, the individual pieces of wood 12, 14 are milled on both their front sides so that finger joints are formed, provided with glue if necessary, and assembled in the pressing station 240 to form a structural element made of pieces of wood 12, 14 pressed together and glued together at the front.

After processing with the cross-cut saw 230, the pieces of wood 12, 14 are transferred to a cross conveyor 212, which extends in segments between the cross-cut saw 230 and the pressing station 240. A longitudinal conveyor 216 is arranged between segments of the cross conveyor 212, which is arranged between the milling stations 110, 140. A feed direction 202 is provided on the cross conveyor 212 and a feed direction 206 is provided on the longitudinal conveyor 216, which is directed perpendicular to the feed direction 202. The individual pieces of wood 12, 14 are arranged on the cross conveyor 212 with their longitudinal extension 16 perpendicular to the feed direction 202 of the cross conveyor 212.

The cross conveyor 212 has corresponding conveying means for moving the pieces of wood 12, 14, for example chains or rollers or the like, which form a transport table that is delimited by table edges 106 and 108. The table side 106, 108 of the respective milling station 110, 140 serves as a stop for aligning the front sides of the pieces of wood 12, 14 so that the front sides and the long sides are precisely aligned and a defined, preferably vertical, angle is set between the front side and long side of each piece of wood 12, 14. Other means for aligning the pieces of wood 12, 14 can also be used, as long as they are suitable for aligning the pieces of wood 12, 14 in a reproducible and identical manner. This facilitates the subsequent pressing of the pieces of wood 12, 14 at their front sides in the subsequent pressing station 240.

On the longitudinal conveyor 216, the pieces of wood 12, 14 are transported in the direction of their longitudinal extension 16, i.e. the longitudinal extension 16 is parallel to the feed direction 206 of the longitudinal conveyor 216.

In front of each of the milling stations 110, 140, stop means (not shown) are arranged, with which the pieces of wood 12, 14 are brought into contact with their long sides in the feed direction 202 of the cross conveyor 212 before they are milled with their front side facing the respective milling station 110, 140. The milling stations 110, 140 shown are each prepared to synchronously form front-side finger joint profiles on at least two individual pieces of wood 12, 14, which are aligned parallel to one another with their longitudinal extension 16.

Longitudinal conveyor units 214, 218 are arranged in front of each of the milling stations 110, 140, with which the pieces of wood 12, 14 can be moved to the respective milling station 110, 140 for processing. Alternatively or additionally, it can also be provided that the milling unit of the respective milling station 110, 140 can be moved to the pieces of wood 12, 14, which in Figure 2 is indicated by a directional arrow 204.

The longitudinal conveyor 216 can be realized in the usual way by means of a roller conveyor and the transverse conveyor 212 with rollers, belts, chains and the like.

The pressing station 240 adjoining the preparation station 100 has an input area 242 through which the pieces of wood 12, 14 can be fed by the cross conveyor 212. The pieces of wood 12, 14 are pressed together there at the front and transported in the transport direction 252.

The Figures 3 to 5 show different phases of the movement of timbers 12, 14 in the preparation station 100 of the Figure 2 . The pieces of wood 12, 14 are the same length in the embodiment shown, but they can also be of different lengths. Furthermore, more than two individual pieces of wood per milling station 110, 140 can be milled synchronously with the milling unit 120 ( Figures 3-7 ) can be milled.

Figure 3 shows a first process step in the transfer of two individual pieces of wood from a cross-cut saw 230 to the first milling station 110, in which the pieces of wood 12, 14 have been moved with the cross conveyor 212 with their front sides along the table edge 106 to the first milling station 110 and have arrived in the working area of the milling station 110. There, the two pieces of wood 12, 14 are stopped in alignment, each clamped with a separate clamping device 112, 114 and milled synchronously with a milling set 122, 124 of the milling unit 120. In the meantime, further pieces of wood 12, 14 are delivered treated by the cross-cut saw 230.

In an alternative embodiment not shown, the milling station 110 can have a milling unit 120 with a milling set 122, which is provided in a width that corresponds to at least twice the width of the pieces of wood that are being trimmed in the trimming station 100. As a result, two end faces of two pieces of wood 12, 14 can be milled synchronously with one milling set 122.

Figure 4 shows a further process step after removing the one-sided milled pieces of wood 12, 14 from the first milling station 110 during the transfer of the one-sided milled pieces of wood 12, 14 by means of the longitudinal conveyor 216 to the side of the second milling station 140, so that the opposite end face of the pieces of wood 12, 14 can also be processed. The new, unmilled pieces of wood 12, 14 are guided with their end faces along the table edge 106 to the first milling station 110, while the one-sided milled pieces of wood 12, 14 are moved to the opposite table edge 108 and along it to the second milling station 140. There, the two pieces of wood 12, 14 are stopped in alignment, each clamped with a separate clamping device 142, 144 in order to be milled there.

Figure 5 shows a further process step in which the timbers 12, 14, which have been milled on both front sides, are transported by the cross conveyor 212 from the second milling station 140 towards the pressing station 240 ( Figure 1 ). Meanwhile, the next pair of timbers 12, 14 milled on one side is moved via the longitudinal conveyor 216 from the side of the first milling station 110 to the side of the second milling station 140, while unmilled timbers are moved with the cross conveyor 212 towards the first milling station 110. Since the lower end face of the timbers 12, 14 in the figure was milled last and this side of the timbers 12, 14 is finally aligned exactly, the pressing and the feed takes place in the following pressing station 240, as in Figure 1 shown, in the figure downwards to the side on which the last milling station 140 of the dressing station 100 is arranged.

Figure 6 shows a front view of the milling station 110 with two milling cutter sets 122, 124 on the milling unit 120 according to an embodiment of the invention. The milling unit 120 can move both milling cutter sets 122, 124 synchronously via a single shaft, for example from top to bottom.

Figure 7 shows a front view of the milling station 110 with a single milling set 126 on the milling unit 126 according to a further embodiment of the invention. The milling set 126 is at least as wide, preferably wider, than the front sides of two adjacent pieces of wood into which finger joints are to be milled at the milling station 110. The pieces of wood can be processed synchronously with the milling set 126.
