Adjustment station and device with an adjustment station

Description

[0001] The invention relates to a finishing station for a device for producing wooden, bar-like or plate-like structural elements assembled at the end faces via finger joints, as well as to a milling station for such a finishing station, and to a device with such a finishing station. State of the art

[0002] When processing wood, which is usually in the form of sticks or plates, it is often necessary to remove any missing sections with unforeseeable lengths from the wood fed into a device in a trimming station at the input. This produces wood of the same cross-section and usually of different lengths. Finger joints are milled into the two ends of the wooden poles, into which glue is applied so that the milled wooden poles are joined and pressed together with their ends in a pressing device downstream of the trimming station to form a continuous wooden strand. Wooden poles of the desired length are then cut off at one end of the wooden strand, while further wooden poles with finger-jointed ends are added to the opposite end. The finger-jointed wooden poles are then 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 timber, such as squared timber, glued laminated timber or glued beams. On the other hand, the throughput of timber through the device determines the efficiency of the device, with the necessary pressing of the timber being a significant time factor, whereby strict specifications must be met with regard to strength and quality.

[0003] AT 505 211 A2 discloses a device for producing end-to-end finger-jointed timbers. The device consists of two milling stations, a pressing station for joining and pressing the timbers, and means for advancing the timbers to the pressing station. These feeding means transfer the timbers to the first milling station and the second milling station. Furthermore, the feeding means transfer the timbers, which have finger-jointed profiles on both sides, to the pressing station. The speed at which the individual feeding means drive the timbers is adjustable, independent of the speed at which the other feeding means drive the timbers.

[0004] DE 20 2020 105 783 U1 discloses a pressing device for a device for producing wood strands from glued, finger-jointed timber. The device comprises an input area through which the timber can be fed, and in which a feed unit is arranged for moving the timber in a feed direction. The device further comprises successive clamping and pressing units designed for clamping and pressing a wood strand consisting of at least two timbers provided with finger-jointed profiles on the end faces and glued together. At least one of the clamping and pressing units is arranged so as to be displaceable 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.

[0005] DE 20 54 807 A describes an end-facing machine for single- and double-sided machining of workpieces of any cross-section. This machine describes a braking device arranged above the conveyor belt, which presses and holds the workpieces against the carriers and supports of the conveyor belt to generate the necessary holding force for the machining units. The machining units are designed as a milling spindle, a pre-slotting spindle, or a cross-cutting saw. The machining units are arranged one behind the other; the end-facing machine further comprises two milling spindles located on opposite sides of the conveyor belt. The milling spindles each mill one end face of a workpiece.

[0006] US Pat. No. 3,802,986 A discloses an end-preparation line comprising a conveyor and a profiling station. The profiling station comprises motor-driven rotating knives that process the end of the wood during transport to provide the end with a tongue and / or groove. Immediately downstream of the profiling station is an applicator that applies a coating containing an adhesive component to the end of the wood piece passing through it.

[0007] DE 30 46 319 A1 discloses a device for joining strip sections of different lengths at the end face. The device comprises a continuously rotating conveyor belt with carriers arranged at a distance from one another transversely to the conveying direction. Finger jointing and gluing devices are arranged offset from one another on both sides of the conveyor belt.

[0008] 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.

[0009] A device for joining blocks is known from US Pat. No. 5,617,910 A. The blocks to be joined are fed to a finger-jointing machine on an intermittently operating feed conveyor, where 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. While the cleat conveyor moves the blocks further through the finger-jointing machine, the unmilled ends of the blocks are picked up by a transfer conveyor, which pushes the blocks across the conveyor belt. The other end is then machined by a second milling machine.

[0010] EP 3 090 849 A1 discloses a production line for elongated wooden workpieces, comprising 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 output 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 end edges and profile cutters for milling the teeth into the aligned end face. In this process, one wooden workpiece at a time is processed on its end face in the processing device. Disclosure of the invention

[0011] The object of the invention is to create a dressing station that allows an improved throughput of milled wood.

[0012] A further object of the invention is to provide a device with improved throughput with such a finishing station.

[0013] The objects are achieved by the features of the independent claims. Advantageous embodiments and advantages of the invention emerge from the further claims, the description, and the drawings.

[0014] 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.

[0015] The invention relates to a trimming station for a device for producing wooden, rod- or plate-like structural elements joined at the end faces by finger joints. The trimming station comprises at least one first and at least one second milling station, each spaced apart from one another in a feed direction and configured to create end-face finger joint profiles at the two ends of individual pieces of wood to be joined. Furthermore, the trimming station comprises means for advancing 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.

[0016] It is proposed that each of the milling stations is prepared in order to form synchronously and simultaneously front-end finger joint profiles on at least two individual pieces of wood aligned with their longitudinal extent parallel to each other at the respective milling station.

[0017] 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.

[0018] In front of each milling station, stop devices are arranged, against which the timbers are placed with their long edges in the feed direction of the cross conveyor before milling. The end edge of each timber is aligned with a stop edge at the respective milling station so that the long edge and the end edge of the timber are at a well-defined angle to each other. Advantageously, several timbers are processed simultaneously and synchronously at a single milling station.

[0019] The timbers can be held securely in position on the cutter sets during the milling process. This allows for wood tolerances to be compensated, eliminating the need for pre-planing. The stop edge, against which the long side of the respective timber is aligned, serves as a zero line for the alignment of the timbers, as does a stop edge for the end face of the respective timber. This stop edge can advantageously be a table side of the conveyor between the milling stations in the trimming station.

[0020] The individual pieces of wood are aligned, in particular with their side edges, parallel to a defined stop edge and are therefore advantageously also aligned parallel to one another. Furthermore, the end edge of each piece of wood is aligned to a stop edge at the milling station so that the long edge and the end edge are at a well-defined angle to one another. The end edge is advantageously aligned perpendicular to the long edge. When the pieces of wood are later pressed together to form a log, the individual pieces of wood can be joined and pressed cleanly and with minimal loss. In principle, an angle between the end edge and the long edge that deviates from a right angle is also possible, so that two individual pieces of wood to be joined together have at least one end side that is inclined complementarily to the long side and are therefore easy to press together.

[0021] The parallel processing of individual pieces of wood in the trimming station allows for precise alignment of the side edges of each piece of wood and precise and reproducible adjustment of the angle between the respective end face and long side. This can reduce waste and improve the pressing result in a subsequent pressing station.

[0022] Advantageously, the throughput of the trimming station can be at least doubled when simultaneously milling at least two individual pieces of wood at each milling station. The trimming station can advantageously be designed as a cycle-chain system that processes pieces of wood in predetermined work cycles. Optionally, the trimming station can also be designed without cycle-chain operation.

[0023] 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 their end faces. Optionally, more than one milling unit can be provided in one or more of the milling stations.

[0024] The milling unit can be designed such that one cutter set of the milling unit is provided with a width that corresponds to at least twice the width of the pieces of wood being trimmed in the trimming station. Milling units are usually designed for specific maximum widths of individual pieces of wood to be milled. Such an arrangement can advantageously be widened accordingly. Additionally or alternatively, a milling unit can have multiple cutter sets that are designed for maximum widths of individual pieces of wood, with the cutter sets processing the corresponding pieces of wood synchronously. Furthermore, the milling unit can have multiple cutter sets that are provided with a width that corresponds to at least twice the width of the pieces of wood.

[0025] According to a favorable design of the dressing station, at least one of the milling units can have at least two cutter sets, with which at least two pieces of wood can be milled synchronously and simultaneously on their end faces. Advantageously, the cutter sets can be moved synchronously for milling, for example, from top to bottom or vice versa.

[0026] The timbers can be elongated elements such as slats, boards, planks, squared timbers or the like.

[0027] 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 cutter sets of the respective milling unit. Advantageously, the cutter sets can be moved synchronously by means of a common drive or feed mechanism, for example, a common shaft or the like.

[0028] According to a favorable design of the finishing 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 at or adjacent to the at least first and / or at least second milling station. Advantageously, a stable and permanent adhesive bond can be achieved during a subsequent pressing process of the pieces of wood.

[0029] According to a further aspect of the invention, a milling station is proposed for a finishing station, comprising a milling unit configured to synchronously form end-face finger joint profiles on at least two pieces of wood aligned parallel to each other with their longitudinal extension. The pieces of wood are aligned parallel to each other, in particular, with their side edges.

[0030] 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.

[0031] In front of each of the milling stations, stop devices are arranged against which the timbers are brought to rest with their longitudinal edges in the feed direction of the cross conveyor before milling and the front edge of each of the timbers is aligned to a stop edge at the respective milling station so that the longitudinal edge and the front edge of the timbers are at a well-defined angle to each other.

[0032] The timbers can be held securely in position on the cutter sets during the milling process. This allows for wood tolerances to be compensated, eliminating the need for pre-planing. The stop edge, against which the long side of the respective timber is aligned, serves as a zero line for the alignment of the timbers, as does a stop edge for the end face of the respective timber. This stop edge can advantageously be a table side of the conveyor between the milling stations in the trimming station.

[0033] The milling station advantageously allows for an increased throughput of wood in a dressing station.

[0034] According to a further aspect of the invention, a device is proposed for producing rod- or plate-like structural elements made of wood and joined at the end faces by finger joints. The device has a trimming station with at least one first and at least one second milling station, spaced apart from one another in a feed direction, designed to create end-face finger joint profiles on the two ends of individual pieces of wood to be connected. The device has a pressing station designed for the end-face joining and pressing of the individual pieces of wood provided with finger joint profiles on the end faces. Furthermore, the device has means for advancing the individual pieces of wood to be processed, starting from an input side via the trimming station to the pressing station.The at least first and at least second milling stations are each prepared to simultaneously form end-face finger joint profiles on at least two individual pieces of wood aligned parallel to one another with their longitudinal extent at the respective milling station.

[0035] 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.

[0036] In front of each of the milling stations, stop devices are arranged against which the timbers are brought to rest with their longitudinal edges in the feed direction of the cross conveyor before milling and the front edge of each of the timbers is aligned to a stop edge at the respective milling station so that the longitudinal edge and the front edge of the timbers are at a well-defined angle to each other.

[0037] The timbers can be held securely in position on the cutter sets during the milling process. This allows for wood tolerances to be compensated, eliminating the need for pre-planing. The stop edge, against which the long side of the respective timber is aligned, serves as a zero line for the alignment of the timbers, as does a stop edge for the end face of the respective timber. This stop edge can advantageously be a table side of the conveyor between the milling stations in the trimming station.

[0038] The woods are aligned particularly with their side edges parallel to each other.

[0039] Advantageously, the throughput through the device can be at least doubled due to the increased throughput through the trimming station. The trimming station can advantageously be designed as a cycle-chain system that processes individual pieces of wood in set work cycles. A cross-cut saw can advantageously be provided on the input side, which cuts the pieces of wood at defective locations. A storage area is expediently provided between the cross-cut saw and the first milling station to ensure sufficient wood is available for increased throughput in the trimming station. The storage area can, for example, be designed as a cross conveyor for pieces of wood.

[0040] 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 their end faces. The milling unit can be designed such that a set of milling cutters of the milling unit is provided with a width that corresponds to at least twice the width of the pieces of wood being dressed in the dressing station.

[0041] This allows at least two types of wood to be processed with one cutter set of the milling unit. Alternatively, the milling unit can have at least two cutter sets.

[0042] Typically, milling units are designed for specific maximum widths of individual pieces of wood to be milled. Such an arrangement can advantageously be widened accordingly.

[0043] According to a favorable embodiment of the device, at least one of the milling units can have at least two cutter sets, with which at least two parallel pieces of wood can be milled on the end faces. Advantageously, the cutter sets can be moved synchronously.

[0044] According to a favorable embodiment of the device, at least one of the milling units can have a common drive for at least two cutter sets of the respective milling unit. Advantageously, the cutter sets can be moved synchronously using a common shaft.

[0045] For example, the milling unit can have a driven pulley, from which a shaft end protrudes axially on each side, each of which houses a set of milling cutters. Such an annular disc can also be arranged laterally on a shaft, and the cutter sets can be mounted on one side of the shaft, with the cutter sets advantageously being spaced apart from each other by spacer rings. The cutters can also be driven directly by a motor.

[0046] According to a favorable design of the device, at least the means for advancing the individual pieces of wood to be processed can be designed as a chain-driven system. The increased throughput of wood can be moved through the device to the pressing station at a suitable rate.

[0047] A suitable pressing station is described in DE 202020105783 U1 and allows for particularly high throughput with high-quality joints between the timbers. Other types of pressing stations, for example, with continuous timber conveyance, are also conceivable. drawing

Embodiment of the invention

[0051] In the figures, components of the same type or function similarly are designated by the same reference numerals. The figures are merely examples and are not to be construed as limiting.

[0052] Before describing the invention in detail, it should be noted that it is not limited to the specific components of the device and the specific method steps, as these components and methods may vary. The terms used herein are intended to describe a particular embodiment only and are not intended to be limiting. Furthermore, when the singular or indefinite articles are used in the description or claims, this also refers to the plural of these elements, unless the overall context clearly indicates otherwise.

[0053] The directional terminology used below, including terms such as "left," "right," "top," "bottom," "before," "behind," "after," and the like, is intended solely to enhance understanding of the figures and is in no way intended to limit the scope of the invention. The components and elements depicted, as well as their design and use, may vary according to the considerations of a person skilled in the art and may be adapted to specific applications.

[0054] 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 detail from a top view. Both figures are described together below.

[0055] The cross-cut saw 230 is used to cut off defective areas from individual pieces of wood, which are then fed to the trimming station 100. This produces pieces of wood 12, 14 of varying 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 ends to form finger joints. These are then glued if necessary. In the pressing station 240, they are joined together to form a structural element consisting of the pieces of wood 12, 14 pressed together and glued at the ends.

[0056] 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 and is located 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.

[0057] 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 defined 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 end faces of the pieces of wood 12, 14, so that the end faces and the long sides are precisely aligned and a defined, preferably vertical, angle is set between the end face 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 reproducibly aligning the pieces of wood 12, 14. This facilitates the subsequent pressing of the pieces of wood 12, 14 at their end faces in the subsequent pressing station 240.

[0058] On the longitudinal conveyor 216, the timbers 12, 14 are transported in the direction of their longitudinal extension 16, ie the longitudinal extension 16 is parallel to the feed direction 206 of the longitudinal conveyor 216.

[0059] In front of each of the milling stations 110, 140, stop means (not shown) are arranged, with which the timbers 12, 14 are brought into contact with their longitudinal sides in the feed direction 202 of the cross conveyor 212 before they are milled with their end faces facing the respective milling station 110, 140. The milling stations 110, 140 shown are each configured to synchronously form end-face finger joint profiles on at least two individual timbers 12, 14, whose longitudinal extensions 16 are aligned parallel to one another.

[0060] Longitudinal conveyor units 214, 218 are arranged in front of each of the milling stations 110, 140, with which the timbers 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 timbers 12, 14, which in Figure 2 is indicated by a directional arrow 204.

[0061] 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.

[0062] The pressing station 240 adjoining the trimming station 100 has an input area 242 through which the timbers 12, 14 can be fed by the cross conveyor 212. The timbers 12, 14 are pressed together there at the end faces and transported in the transport direction 252.

[0063] The Figures 3 to 5show different phases of the movement of timbers 12, 14 in the finishing station 100 of the Figure 2 . In the illustrated embodiment, the timbers 12, 14 are of equal length, but they can also be of different lengths. Furthermore, more than two individual timbers per milling station 110, 140 can be milled synchronously with the milling unit 120 ( Figures 3-7 ) can be milled.

[0064] Figure 3shows 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 their end faces along the table edge 106 to the first milling station 110 by the cross conveyor 212 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 respective 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.

[0065] In an alternative embodiment not shown, the milling station 110 can have a milling unit 120 with a milling cutter set 122, which is provided with a width that corresponds to at least twice the width of the pieces of wood being dressed in the dressing station 100. This allows two end faces of two pieces of wood 12, 14 to be milled synchronously with one milling cutter set 122.

[0066] Figure 4shows a further method step after the removal of 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 machined. The new, unmilled pieces of wood 12, 14 are fed 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 to be milled there.

[0067] Figure 5shows a further process step in which the timbers 12, 14, which have been milled on both end faces, 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 take 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.

[0068] Figure 6shows a front view of the milling station 110 with two cutter sets 122, 124 on the milling unit 120 according to an embodiment of the invention. The milling unit 120 can move both cutter sets 122, 124 synchronously via a single shaft, for example, from top to bottom.

[0069] Figure 7 shows a front view of the milling station 110 with a single cutter set 126 on the milling unit 126 according to another embodiment of the invention. The cutter set 126 is at least as wide, preferably wider, than the end faces 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 machined synchronously with the cutter set 126. Reference symbol
