Definitions
- the present invention relates generally to the field of wood product assembly. More particularly, the present invention relates to an apparatus for assembling, gluing, and clamping wood pieces to produce an engineered wood product.
- the wood product may be a solid board cut to a specific size, or an engineered product created by joining together wood blocks or pieces in a specific orientation.
- small blocks of lumber may be assembled end to end using a glued fingerjoint, and fingerjointed or natural lumber may be glued edge to edge or face to face into a panel or beam.
- slow curing glues provide the user with substantial working time prior to curing of the glue, but require the assembled product to be held or clamped for a relatively long time (often several hours) during the curing process to ensure proper bonding between adjacent pieces of wood.
- a method for face gluing wood laths within a clamping system comprising the steps of: a) applying glue to a wood lath while conveying the wood lath onto a retractable lath support; b) retracting the lath support to allow the wood lath to drop onto an assembly surface; c) repeating steps a) and b) as required with or without glue application for at least one subsequent lath wherein prior to step b) the lath support is reset; and d) applying a clamping pressure perpendicular to the assembly surface to form a glued wood product.
- an apparatus for gluing and clamping wood laths comprising: a frame; a glue application system operably connected to the frame for selectively applying glue to a wood lath; a conveyor system for conveying the wood lath onto a retractable lath support operably connected to the frame, the retractable lath support operable between an extended position for supporting a lath and a retracted position for allowing a wood lath to drop onto an assembly surface; and, a clamping system operably connected to the frame for applying a perpendicular clamping pressure to the assembly surface to form a glued wood product.
- Fig. 1 is a schematic front view of an apparatus in accordance with one embodiment of the invention.
- Figs. 2A, 2B, and 2C are schematic plan views of an apparatus and conveying system during various stages of product assembly;
- Figs. 3 A and 3B are schematic side views of an apparatus in accordance with one embodiment of the invention during various stages of product assembly;
- Fig. 4A and 4B are front views of an apparatus in accordance with one embodiment of the invention, with the side door shown in both open and closed positions; and, Fig. 5 is a schematic diagram of two adjacent clamping systems in accordance with one embodiment of the invention.
- the present invention provides a method and system for gluing, assembling, and clamping wood pieces (laths, panels or boards) into an assembled engineered wood product.
- a system 10 is provided that allows for rapid assembly of individual laths, panels or boards (hereinafter laths) into a multi-board/panel wood product.
- the front of the apparatus 10 generally includes a loading area 20 for receiving laths or panels 90, a glue application system 30 for applying glue onto laths 90 as they are loaded lengthwise into the loading area 20, an elevator 40 for adjusting the vertical position of the loaded laths 90 such that each newly introduced lath comes to rest on the glued surface of the previously loaded lath.
- a press plate 50 When all of the laths are assembled in the apparatus, a press plate 50, actuated by hydraulic presses 60, clamps the assembled wood product together during curing of the glue.
- the apparatus also includes a side door 70 and chain transfer system 80 for removing the assembled wood product from the apparatus IO upon release of the clamping pressure.
- an individual lath B is conveyed on rollers 110 to a position proximal to and in line with the loading area 20 of the apparatus 10.
- a previously loaded lath A is supported by the elevator 40 with the surface to which glue has been applied facing upwards.
- a number of retractable board supports 25 are slidably mounted on board support shafts 26 within the loading area 20.
- glue is applied by the glue application system 30 onto the upper surface of the lath B.
- the lath B will be received within the system 10 by the board supports 25 and will be advanced until it abuts an upwardly extending stop 41 at the dow ⁇ nstream end of the system as shown in Figure 2B.
- the board supports 25 are retracted over the support shafts 26, to drop the lath B onto the glued surface of lath A, with the glued surface of lath B exposed.
- the board may be manipulated by an optional positioning system (shown schematically as arrows 45) to adjust the orientation of the board, as necessary to ensure alignment of successive laths.
- a new lath C is advanced towards the loading area 20 by the rollers 110.
- the elevator is subsequently lowered by the thickness of one lath and the board supports are again extended to prepare for loading of the next lath C.
- the press plate 50 may be segmented and matched with single or paired hydraulic presses 6O enabling the individual control of various segments of the press plate for increased flexibility in the clamping process.
- a transfer system 42 engages the underside of the wood product and removes the assembled product dfrom the apparatus through the open side door as shown in Figures 4 A and 4B.
- Rapid Lath Advancement As noted above, it is preferred to load boards into the apparatus as quickly as possible both to speed production, and to minimize the time each glued surface is exposed to air.
- Rapid advancement of laths into the apparatus is accomplished by the roller system 110, which in current embodiments can advance laths at a rate of 1200 feet/minute. At this rate, each lath is advanced into the apparatus with significant force and inertia and an appropriate stop system 41 should be provided to reduce or eliminate any lcick-back of each board. It is contemplated that significantly higher rates may be achieved in the order to 2500 feet/minute.
- glue curing times are balanced against the time required to fully load the system and clamping times.
- the total loading time will be in the order of 75 seconds.
- the glue applied to the first lath must not cure before the clamping system has been engaged.
- the clamping time must be long enough to ensure that the glue on the second last lath is fully cured before release.
- the glue must provide a minimum working time in the order of 75-100 seconds.
- the total clamping time is determined by the minimum working time plus the cure time (ie the time from when the glue begins to set up until it is acceptably cured). Glues with faster cure times will improve the overall speed of production provided they have sufficiently long working times.
- Glue compositions can be formulated wherein the total clamping time is in the range of 2-5 minutes.
- the efficiency of the system can be further improved by associating more than one apparatus 10 with each roller/conveyor system such that almost continuous production can be achieved. That is, by successively loading parallel systems X and V as shown in Figure 5, a manufacturing facility can be made to load one side X while trie other side Y is clamping. For example, if it takes approximately 75-100 seconds to load one side and total clamping time is in the range of 2-5 minutes, each side will be discharging product roughly every 3.5 to 7 minutes. In order to achieve this parallel efficiency; a lath delivery system 80 would selectively deliver individual laths to either the X or Y side of the facility.
- the Y side may be provided with a stop 81 that would selectively prevent lateral travel of a lath A to the X side when programmed to advance.
- stop 81 By selective advancement and retraction of stop 81, laths would be positioned for loading the Y and X sides of the system respectively.
- wood product may be removed from alternate sides of the system 10.
- retractable board supports 25 are slidably mounted around board support shafts 26. It is preferable that the board supports retract over the support shafts, as glue may drip over the side of a lath and make contact with the board supports 25. Retraction over the support shafts 2.6 will therefore decrease the likelihood of glue contacting the support shafts and thus, minimizes the risk of glue contacting the moving parts.
- board supports 25 and shafts 26 in a staggered configuration on either side of the apparatus, it is understood that board supports need not be staggered, and may be present only on one side of the loading area 20.
- the apparatus and associated parts are controlled by an electronic system to control and monitor the advancement, gluing, assembly, and clamping of the laths, and removal of the product from the apparatus.
- the control system may include various processors, logic, and sensors for determining the position of laths and for detecting problems during assembly as understood by those skilled in the art.
- the system could be preset to assemble particular products by controlling the glue application system 30, hydraulic presses 60, transfer system, roller system 110, and extension and retraction of the board supports 25 as appropriate.
- the positioning system 45 may also be enhanced to laterally clamp the laths during the main clamping phase.
- lateral clamping is beneficial to ensure accurate alignment of the boards which will minimize or reduce the degree to which the product will ha_ ⁇ ve to be dressed post clamping.
- the clamping system may be modified to enable a cambered wood product to be created. That is, during the assembly and main clamping phases, the supports for the laths may be adjusted thus permitting a non-linear support surface to be created. Accordingly, through adjustment of the position of individual hydraulic presses (or pairs), the hydraulic pressures can be made to apply an appropriate clamping pressure against the non-linear support surface thus creating a cambered or curved product.
