Description

2~073~3 BACKGROUND OF THE INVENTION

Field of the Invention This invention relates to the formation of panels of wood by gluing together smaller sized pieces of wood so as to utilize scrap wood materials which would otherwise be discarded and form usable panels therefrom.

Des~ription of R~lated Art Elmendorf, U.S. patent no. 1,428,765, October, 1922, forms sheets of wood from edge-glued wood strips using spacing grids formed by bars. Rails allow the strips to slide on the grids. The grids are used to carry edge-glued strips which are manually placed on each grid. A number of such supporting grids are shaped by stretching and compressing.

Frisch, U.S. patent no. 2,526,342, October, 1950, shows edge-bonding apparatus where glue is applied to the edges of the boards on an infeed table. The glued boards are fed into an area where a plurality of horizontal plungers apply pressure across the end of the edge-bonded boards. Upper and lower platens are provided which move into and out of engagement on the boards as same move into the pressurized area of the apparatus. The upper and lower platens apply RF energy to the wood to cure the glue in the gluing operation. Figure 10 of this patent shows a plurality of plungers utilized in the apparatus. The plungers serve to apply pressure uniformly to the sides of the board already selected for gluing. The plungers do not *~

20073~3 serve to advance selected boards beyond a predetermined point for further processing.

Schroeder, U.S. patent no. 4,195,346, March, 1980, shows an appara-tus to sort and classify lumber utilizing a computer programmed to select certain pieces. Schroeder's system selects based on the length and quality of the lumber and develops electrical contr~l signals from these inputs.
The control signals indicative of length and quality are fed into a computer programmed to select optimal cut-off length and optimum quality and to feed these selections to cutting or sorting apparatus so that the appropriate operations can be performed on selected pieces of lumber.

The Schroeder system is designed to work in a saw-mill. Schroeder requires and ralies on a visual inspection made by a human inspector who manually depresses buttons he selects based on the inspectorls judgment made by viewing the board. The boards so classified by the inspector are transferred on a sorting conveyor. Kickers are provided to knock off the boards so that they are placed in selected bins. Schroeder requires that an operator manually depress buttons indicative of criteria of wood boards which he observes from his inspection station. The computer then, based on preset criteria, compares the results of the signals generated by the depressed buttons with preset information and causes the boards to be conveyed automatically to preselected locations for further processing in the saw-mill.

arino, U.S. patent no. 4,512,840, April, 1985, shows a machine for forming planks by gluing a number of . .

i 20~73~3 wood fillets together. The planks are obtained from uniform sized wood fillets. Each plank is thirteen fillets wide and several metres long. Marino shows a feed station for the thirteen fillets. As the fillets are all of uniform size, Marino does not require any sizing, selection or processing based on the results of size analysis.

SUMMARY AND OBJECT OF THE INVENTION

Ths present invention relates to a method and apparatus for selecting wood stock of various sizes automatically and to convey the stock to a series of locations which carry them to work areas where gluing rollers and other operations are p~rformed to process the selected pieces of stock. Specifically, the invention employs a track section with thirteen distinct tracks having conveying means in which thirteen pieces of wood stock are positioned. The pieces of stock are of uniform length and thickness but are of unequal widths. The boards are placed in each of the tracks with their non-uniform dimension upright in the track.

The conveying means brings all of the separate wood boards up to a scanning area. The scanning area utilizes a track mounted analog proximity sensor positioned perpendicularly to the conveyor for the boards so that the proximity sensor will scan the height of each of the thirteen boards each time the scanner passes along the length of its track. The data received from the scanning sensors as to the height of the various thirteen boards is fed to a computer which computes which combination of the thirteen boards equals a predetermined size for the desired ;. .

20073~3 panel.

The computer then actuates a controller which, in turn, actuates selected ones of thirteen separate solenoid valves to control air to thirteen cylinders to raise or lower thirteen gates at the ends of each of the thirteen wood stock tracks. Conveyor means then conveys the selected boards to a secondary conveyor which carries them to a subsequent work area where gluing rollers and various other operations coact to further process the selected boards.

The wood gluing art is long recognized the need to automate what, for many years, has been essentially a manual operation. The field requires the cutting and sizing of strips of wood which are then glued along their edges, clamped together, the glue allowed to set, and the wooden panel, thus formed, removed for furthPr processing. Examples of various machinery developed to automate the steps of this operation are shown in U.S. patents 4,374,165, 4,062,320, 4,489,925, 3,771,779 and 4,773,555, all commonly assigned.

The present invention represents a further extension of the automation of the various steps of the wood gluing process. This invention automatically selects and transmits to further work stations appropriately sized pieces of stock which, when glued together (utilizing various of the apparatus shown in the art ~or gluing such strips together), saves time in the formation of the end products.

The system described in U.S. patent no. 4,934,328 has proven itself in operation; however, it has been found '~;

2~073~3 that its utility would be enhanced if the additional functions (described in this application) were added. These functions permit the system to provide additional information to and control for the operator; namely, (i) a count of the number of panels made by the apparatus and generation of control signal (which can be used to stop the apparatus) when a preset number of panels are made; and, (ii) generation of a report (on a screen or on a prin~er) covering the production on the machine during a time period which generates information by panel size, panel area, board feet, specie, and operator identification.

These features are incorporated in the system by modification of the computer program and the addition of a printer to give a permanent record of the display.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
.
Figure 1 is a top view of the apparatus employed in the invention~ Figure 1 consists of two main sections; an infeed section 2 i5 provided to the left of Figure 1 which includes lnfeed table surface 320 The infeed table surface 32 serves as a working surface which enables the operator to stack pieces of wood in thir-teen separate tracks shown generally at 30. The operator has avail-able to him a hand held push button controller 48. When the operator has filled the tracks 30 with pieces of wood, the operator depresses the push button on controller 48 to activate the appar-7 atus. The thirteen tracks each may contain a number o~ uniform length, uniform thickness but not non-uniEorm width pieces of wood. These thirteen tracks extend along the length of the frames supporting infeed section 2 until they pass beneath a scanner section shown yenerally at 84.

Each of the thirteen tracks 30 end in respective ones of thirteen gates shown generally at 28 in Pigure 1. The gates permit a num~er o selected boards to pass on to the second main section of the apparatus; the output section 4.

Thi~ scanner section is fo~lowed by an out~eed section shown generally at 4. The outfeed section takes the selected boards from the gates and conveys them to a work station after passin0 the boards throu~h a concentrator. The concentrator .9_ ~AYL~ 3.0-010 ~ ~7 3 43 consists of rails 12 and 14 which serve to concentrate and compress the boards into a compact arrangement and may be located centrally of the outfeed section 4~ The boards thus concentrate~ are in turn passed over the glue roller 10. Glue is applied to the boards by roller 10 on one edge thereof and are then conveyed to a wand a which acts as a stop wand or feeler. ~and 8 is pivoted about a spring-loaded pivot mounting 6~ Movement of the wand to th~
posltion shown in Figure 1 stops the apparatus. Release of the wand from the position shown in Fi~ure 1 permits the apparatus to operate. The wand 8 is caused to release from the position shown in Figure 1 when the bundle of boards which has ca~ed the wand to move its "of~" position as shown in Figure 1 is removed by ~he operator for further processiny.

The outfeed séction 4 of Fi~ure 1 includes a number of rotatable roller rails 16. These roller rails 16 are chain-driven by chains 22, 44 and 42 in Fi~ure 1. The set o roller rails 16 conveys the boards from the gates 28 through the concentrators 12 and 14. Another set of roller rails 18 controlle~ by chain drives 38, 40 and 20 ~ake the boards from the ~lue roller lQ to the end of the apparatus at stop wand 8~

As ~hown in Figure 2, a sid~ view of the apparatus oE
Fi~ure 1, ln~eed table sùrface 32 is connected to the thirteen ra~ls in conveying sectlon 2 of the appar~tusO

Figure 2 also shows a keyboard 48 with a liquid crystal display, The-keyboard 48 is mounted on a panel adjacent the '.1; ~!"' ' :
scanning section. This keyb~ard allows the scanning apparatus to : J
~AYLC 3.0-010 ~ ~ ~7 be set with selection parameters which will be described in con-nection with the computer program by which the apparatus operates as further described in connection with Figures 9 and 10 hereof.

The side view of Figure 2 also shows a plurality of sets of boards located at various points along the apparatus.
Also shown in Figures 2 and 5 is a vertical support bar 86 which mounts the scanner section of the apparatusO The scanner section consists of an ultrasonic analog scanner S0 and a digital proximity sensor 52. Each of these scanners are mounted on a supporting bracket 96 which is, in turn, mounted to a rodless cylinder 24.
As is known in the art, a rodless cylinder is an air driven device which allows a carriage to move from one side of the apparatus to the other. This is commercially available apparatus identiied as model BC100-lPx30" manufactured by Tolomatic and is employed in the present invention to move the scanners 50 and 52 across the entire width of the thirteen channels 30. The rodless cylinder ls mounted on bracket supports 86 and 88. A plate 84 is mounted on the top of the rodless cylinder 24. Plate 84 has thirteen stopnuts shown generally at 26 mounted therein. The stopnuts 26 provide an indication of location by proximity to sensor 52. The analog proximity sensor 50 develops electrical signal~ based on ultrasonic detected signals indicative of the width (height in Figures 2 and 5~ of each of tlle boards. The digital proximity sensor 52 detects which channel the analog sensor is measaring by a count of pulses indicative of sensing its proximity to the stopnuts 26. More particularly, a count from . . . . . .
one to thirteen i~ ~eveloped as the proximity sensor 52 moves TAYLO 3.0-010 ~o7~3 across the rodless cylinder 24 from one end to the other.

As shown in Figures 1, 2 and 6, an electric eye circuit 60 is provided to generate a signal indicati~e of boards passing in the path of the electric eye 60. Numeral 90 denotes the elec-trical lead wire connecting the sensors 50 and 52 to ths computer portion of the apparatus.

Figure 3 shows the infeed section of the apparatus of Figures 1 and 2 in more detail. In Figure 3, the infeed table 32 is mounted on a support bracket 76. One of the thirteen wood feed-ing tracks is shown in Figure 3~ This track is formed between rails 68 and 70~ A piece of wood 66 is shown edge-mounted between tha rails 68 and 70. The rails 68 and 70 are fastened to lateral frame supports such as 33 by a mounting fastener suitable to the materials of which the rail 68 and the support 33 is formed such as shown generally at 64. A chain drive is shown at 74 and serves to rotate roller rails such as 72, 78 and 80 to convey the wood piece ~6 alony the length of the infeed rail structure. As shown in Figures 3 and 4, the structural support is provlded by two com-plimentary U-shaped brackets 62 and 82. These brackets serve to provide structural integrity for the infeed section as well as to provide a safe protected covered housing for the chain drive 74.

Fiyure 5 shows the scanning section of the invention.
As will now be seen, thirteen boards o uniform length and thick-ness but different widths are presented beneath the scanning section. These boards are designated by numeral5 1l 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23 and 25. The boards are located beneath .

TAYL~ 3.0-010 200~3 the two scanners: the analog scanner 50 and the digital scanner 52.
The scanners 5~ and 52 are mounted on the rodless cylinder 24. The rodless cylinder is coupled to the scanners via scanner mounting bracket 98, 96. This bracket consists of U-shaped portions having a short leg 98 and a lon~ leg 96. Proximity di~ital sensor 52 is mounted on leg 96 and analog sensor S0 is mounted between leg 96 and short leg 98. As is known in the art, rodless cylinder 24 is coupled to the bracket 96,98 and, under control of air lines 94 and 92, serves to slide bracket 96, 98 from one side of cylinder 24 to the other at a uniform rate. There is also mounted on rod-less cylinder 24 a mounting plate 84 which contains the thirteen stopnuts shown generally at 26. It is these stopnuts that co-operate with and are sensed by ~he proximity sensor 52 so that actual signals indicative of the count o each stopnut from one through thirteen are developed for each scan of the sensors 52 and 50 across rodless cylinder 24. The rodless cylinder 24 is in turn mounted on the remaining apparatus by vertical supports 86 and 88. The brackets 86 and ~8 are coupled to support rails 100 and 102 in Figure 5 and 62 and 32 in Figures 3 and 4 (for support 88) via a bar such as 104 which is fastened to rail 100.

An important feature of the invention is shown in Figure 5 as calibration block or gauge block 54. This gau~e block con-tains two surfaces, a top surface 56 and a lower surface 58 located coincident with the level of the surface of the rails (one rail is shown in Figure 5 at 27). As will be explained later, analog ultra-sonlc sensor 50 utilizes these surfaces as calibration surfaces for the scan so as to ~au~e the range oE widths of the pieces of wood.

...
TAYLC 3.0-010 2~073~3 Figure 6 shows the gauge block 54 in more detail. In Figure 6, the gauge block is viewed from the end opposite that shown in Figure 5 so that two of the thirteen ~ates are also seen ln this showin~ More particularly, Figure 6 shows the mounting bracket supports 104 and 86 for the scanning section~ These brackets are connected to support rails 102, 1~0 as discussed in connection with Figure 5. The gauge block 54 has a top surface 56 and bottom surface 58 formed therein. Two pieces of wood 19 and 21 are shown in Figure 6 having arrived at the end location for the infeed section of the apparatus. Electric eye 60 is mounted to support rails 102, 100~

Each of the thirteen channels are controlled by gates which consist generally of a solenoid operated air cylindex 106 and a movable gate element 108 mounted to the air cylinder~ When the cylinder is actuated, the element 108 is caused to drop down rom the position shown in Figures 6 and 7 applicable to board 21 to the lower position shown in Figures 6 and 7 applicable to board 19. This allows the board 19 to advance to the next station.
In Figures 6 and 7 t nwnerals 27, 29 and 31 denote the support rails or the channels in whlch boards 21 and l9 are carried.
The cylinders are mounted on and supportec~ by mounting plate 110.

Figure 8 shows the outfeed portion of the apparatus.
Figure 8 show~ three groups of boards progressing from the gates 108 through the glue roller 1~ As shown, the boards are con-centrated by two rails 12 and 14 which are mounted such that the , ,boards are caused to move closer to each other before they pass ' ', .

TA~ ,R 3.0-010 ~73~3 over edge-gluing roller 10. Numeral 40 denotes one of the chain drives for the roller rails employed in the section of rails down-stream of the glue roller 10 and chain drives 22, 42 and 44 o~erate the section of rails 16 located upstream of the glue roller 10.

Figure 9 is a diagram which shows the electrical con-nections of the various elements previously described in connec-tion with Figures 1-8. The apparatus employs drive motors 112 and 116. Motor 112 operates infeed section 2. Motor 116 controls the glue roller 10, the intermediate section roller rails 16 upstream of glue roller 10 and the rails 18 downstream on controller 48 of glue roller 10. A push button on controller 48, described in connection with Figure 2 above, causes the apparatus to startl stop and scan under control of the operator.
The controller 48 permits the operator to select the width of the panel to be formed by the pieces, the number of pieces to be selected and the tolerance applicable to the selection. These signals are fed to computer 114. Computer 114 also receives as inputs, the outputs o dlgital proximity sensor 52 and analog sensor 50 from the scanning system. The computer 114 is also connected to receive the input of the electric eye sensor 60.
The computer controls the gates 106, 108 to seleck the boards for passage to glue roller 10 until de-energized by stop wand 8 on mounting pivot 6. A printer 200 is connected to computer 114~

The following table shows the manufacturer and model number of each of the elements of Figure 9:

Gates 106,108 - Bimba I91-D l-1/16 bore x 1" stroke In practice, the number of thirteen different tracks from which the desired number of boards is to be selected was empirically derived. The number of boards required to make up a panel of the desired thickness could be more or less than thirteen depending on the variations in the output panel size desired and , the size of the input stock from which the panel is to be formed.

With respect to maximum and minimum sizes, in operation~
Applicant has found that the boards can vary in size from one inch to six inches in width theight when used in the apparatus).

The scanning section can sblect panels of any total width even wider than 13" x 6". The selector accomplishes this by making a number of runs. For example, if a panel of 200" is desired, even though the apparatus provides only thirteen pieces of a maximum 6"
height, three separate runs would be performed. On the first run, all the boards would be selected~ On the second run, agaln all the boards would be selected. On the third run, the number of boards necessary to give a total number of 200" would be selected.

If the scanning cannot select boards within the desired , ',tolerance (for example, lS" + or - 1/32") ~hen it selects the TAYLO 3.0-010 2007~43 combination that is closest to and larger than the desired size.
The flow chart for the program described below is shown in Figure 10 hereof. The computer program for controlling the apparatus is set forth below.

The program instructions for printing the information concerning operations of the apparatus are in the lines labeled, "PRINTER OUTPUT" . These instructions print information consist-ing o customer code, panel width, length, thickness, number of panels and number of boards. The information regarding produc-tion totals can also be printed.

The program instruction for generating a count alarm to stop the machine when a preset number of panels are produced are labeled, "COUNT ALARM IS REACHED".

he flow chart of Figure 10 is presented to aid in understanding the operations described in the computer program listed above. In Figure 10, numeral 100 denotes start of the ~lowchart. Numeral 102 denotes the settings formed by the u~er utilizing keyboard 48, descri~ed in connection with Figure 9 above. Standard diagnostic tests performed on the computer operations are indicated at numeral 104 in Fi~ure 10~

Steps 106 and 108 in the flow chart indicates the lack of the indication that the apparatus should stop; namely, that no key on the controller 48 has been depressed or no indication that the stop wand 8 is in the position shown in Figure 1.

The next function 110 is to scan the boards and again, in 112, sense that any key is depressed. The boards are selected through the combination of func~ions 114, 116, 118, 120 and 122.
Again, the sensing of whether any key is pressed, is indicated in block 124. The boards are then sent to glue applicator, as indicated at 126 in Figure 10.

The equations for measuring a particular board will be described below.

In the equations followin~, the following applies:

Vl = value of 6" reference left (or riqht); V2 - value of 1" reference left; V3 = value oE 1" reference right; Vn =
valus of a selected workpiece; dn = the distance to the workpiece selected ~iOe. Vn); and d3 = distance between V2 and V3.
~ . .

T~YLOi `.0-010 ~73~3 , .
Calibration from far left to far right tor vice versa) is represented by the following equation:

91 = dn (V3 - V2~ ~ V2 g6 = dn tV3 - V2) ~ V
~3 ~3 The above equation is desi~ned to calibrate the hei~ht above the boards of the analog sensor and the digital sensor.
The calibration e~uation above recognizes that the hei~ht may be uneven from one far end support to the other. More specifically, and with reference to Figure 5 for example, the hei~ht of the scanning support 98,96 as mounted on rodless cylinder 24 and support0d by vertical supports 86,88 may not be uniform from one end to the other. Thus, the 6" references and the 1" references are used in the program to develop the calibration signals ~1 and g6 representative of any difference in height of the mounting oE
the analog scanner. More specifically, if the analog electrical signal V3 is greater than V2 then a calibration signal 91 is generated in lines "gl" and "~6" Of the computer program described infra. The signal is 0enerated for the hoard located at a location Dn corresponding to the volta~e Vn. Xn this manner, the computer program generates a correction signal for each board location representative of the hei~ht differentlal hetween the two references, V3 and V2.

The height calihration is developed in the equation which follows. In this equation, the difference between the 1"
reference and the 6" reference is utilized to establish in the program calibration oE each of the locations g1 --~0--~AYLo~ 3.0-010 The height calibration is represented by the Eollowing equation:

Height = 1 ~ 5(g1 ~ Vn) gl ~ g6 My invention recognizes that there are several alter-natives to approaching computer analysis of a multiplicity o different sized boards so as to determine which of the boards make up the desired width panel.

One way to size the panels is to go through the signals representative oE the size of each board and adding up the sizes, comparing them to the desired size and goin~ immediately to the next comblnation if the combination size exceeds the maximum allowable panel size. This approach involves the necessity to perform calculations on every comhination o panels.

Another method which may be employed is to take the first n (say 5) boards such that the total size ~i5 over the desired panel width. Then, from this combination o~ the ~irst n boards over the panel width, combinations of boards are subtracted rom the total size to get a result of the proper size. The advantage in this method is that you are taking combinations of boards at a time so that a more rapid process is involved in reaching the combination of the desired size.

One o the problems in workincl with this approach is that combinations o boards are repeated. ~or example, if in . .
thi~ approach ei~ht boards are being exarnined subtracting one, ~3073~
TAYL~, 3 . 0--010 two, three at a time and no combination is found, the approach must look at nine boards so that any combination that subtracts the ninth board involves simply a repeat of one oE the combinations tried when looking at ei~ht boards.

The approach employed in the present program involves several repeats. Lines "make a panel" through "can't find withln tolerance" of the program described infra control the selection process such that, for example if nine boards are being tried, the program avoids any combination that subtracts the ninth board (as this was already accomplished in analysis of eight boards). Further, if a combination of ten boards is being analyzed, the program does not calculate any combination based on subtraction of board number ten.

In establishin~ the methods above, the determinations were based on a test of sizing panels 121' to 30" wide on a machine with thirteen slots and board sizes ranging from 1" to 3"~

Obviously, depending upon other numbers of boards, panel sizes~ and combinations, other differing methods may be employed.

While a specific embodiment of this invention is described as is shown herein, it is to be understood that other embodiments may be resorted to without departing from the spirit and scope of the invention.
