Description
- This application claims priority under 35 U.S.C. § 119 and applicable foreign and international law of U.S. Provisional Patent Application Ser. Nos. 60/405,067 and 60/405,069 filed Aug. 20, 2002, each of which is hereby incorporated by reference in its entirety for all purposes.
- This application incorporates by reference in its entirety the following U.S. patent applications and patents: U.S. patent application Ser. No. 09/578,806 filed May 24, 2000 entitled “Automated Fence Control Coupling System”; U.S. patent application Ser. No. 09/861,231 filed May 17, 2001 entitled “System and Method of Marking Materials for Automated Processing”; U.S. patent application Ser. No. 10/104,492 filed Mar. 22, 2002 entitled “Automated Fence Control Coupling System”; U.S. Provisional Patent Application Ser.

Nos. 491,307; 2,315,458; 2,731,989; 2,740,437; 2,852,049; 3,994,484; 4,111,088; 4,434,693; 4,658,687; 4,791,757; 4,805,505; 4,901,992; 5,251,142; 5,443,554; 5,444,635; 5,460,070; 5,524,514; and 6,216,574.
- The invention relates to devices for controlling linear movement of an object such as a fence on a table saw. In particular, an aspect of the invention involves movement of a positioning carriage along a guide rail, and related assemblies.
- Significant effort and attention has been directed over the years at automating material handling and manufacturing. Ultimately, material processing equipment must be cost effective to manufacture and use. Therefore, innovation is needed to produce manufacturing equipment that is affordable, in view of its intended use, without sacrificing or comprising precision, accuracy, and overall functional performance.
- Table saws may be equipped with a movable fence to allow an operator to set desired cut dimensions. Table saw fences typically are movable along a rail that is bolted along one side of the table saw. An operator may slide the fence back and forth along the rail and then lock the fence in place by means of a locking handle. Many such table saws are sold in a design that requires manual adjustment of the fence.
- Sometimes it is desirable to use a table saw in an automated or semi-automated capacity. Digital positioning systems are available for adding on to a table saw that has a manually operable fence. Aftermarket automated fence positioning systems may be cumbersome to install. Some positioning systems are not flexible enough to be easily mounted on different table saw configurations. Thus, an object of the invention is to provide an automated fence positioning system that is easy to install and to adapt to different table saw designs.
- Another object of the invention is to produce a table saw control system that is less expensive to produce compared to prior control systems, without compromising speed, precision, and accuracy criteria.
- The invention provides automated fence positioning systems that quickly and accurately reposition a fence in the course of executing a pre-determined cut or sequence of cuts on a table saw. An aspect of the invention utilizes a screw member substantially enclosed in a cylindrical housing. The housing has a longitudinal opening and a guide rail structure adjacent the opening. A carriage is mounted on the screw member and configured to travel back and forth along the guide rail structure. The carriage is rigidly coupled to a fence structure so that rotation of the screw member results in translation of the carriage and associated fence structure.
-
FIG. 1 is a perspective view of an automated fence positioning system. -
FIG. 2 is a partial cross-sectional view of the system shown inFIG. 1 . -
FIG. 3 is a close-up view of a coupling device shown inFIG. 2 . -
FIG. 4 is a partially exploded view of a rail section and a carriage device configured to move inside the rail. - Examples of the invention include numerous aspects and permutations. A preferred rail and carriage assembly implemented on a rip fence is described below with reference to
FIGS. 1-4 . -
FIG. 1 shows a perspective view of afence control system 20.Fence 22 is provided on a table saw to index a piece of material for cutting relative to sawblade 24.Fence 22 is connected tofence support member 26 which is slidably connected tofence positioning rail 30. Fence positioning rail is coupled to positioningguide rail 34 viaclamps Carriage coupling device 40 rigidly connectsfence support member 26 to a carriage (shown inFIGS. 2-4 ) which moves insidepositioning guide rail 34. Screwmember 42 is driven by belt andpulley assembly 44 and a motor insidehousing 46 to move the carriage along withcarriage coupling device 40, fence support member, andfence 22 to properly position materials for cutting. -
FIG. 2 is a cross-sectional view through the assembly ofFIG. 1 showing the linkage betweeninternal carriage 50 andcarriage coupling device 40. A close-up view of the linkage is shown inFIG. 3 . Carriage 50 has a cylindrical portion that has internal threads complimenting threads onscrew shaft 42. The cylindrical portion ofcarriage 50 is contained entirely insidepositioning guide rail 34. Carriage 50 also has aflange portion 51 that extends throughslot 52 and runs substantially the entire length ofpositioning guide rail 34.Flange portion 51 includes three T-slots. One T-slot hasanti-friction surface material 54 so thatcarriage 50 can move with a low coefficient of friction relative to T-structure 55 onpositioning guide rail 34. Two other T-slots are provided. T-slot 56 a receives one or more bolts for securing fencestructure coupling device 40. T-slot 56 b receives one or more bolts for securinginterlock plate member 57 a.Interlock device 57 b is mounted onplate member 57 a, and operates to prevent operation of the machine while the carriage is moving. The T-slot configuration shown inFIG. 3 provides a rigid, sturdy connection betweencarriage 50 andcarriage coupling device 40, thus enablingcarriage 50 to move smoothly on asingle rail portion 55 without contacting any other internal surface insidepositioning guide rail 34. Therefore, the positioning system can operate with significantly less friction making the device more efficient to operate and less expensive to produce compared to prior positioning systems. Alternative slot arrangements may be used. Other types of fastening devices, for example, bolts with nuts, soldered or welded connections, etc. may also be used. - In
FIG. 4 , a portion of positioning guide rail orhousing 34 receivescarriage 50.Carriage 50 includescylindrical portion 60 connected toflange portion 51.Flange portion 51 includes three T-slots FIG. 3 .Collar members carriage 50, and are provided withinternal threads 74 complimenting external threads onscrew 42. - In operation,
cylindrical portion 60 is contained inhousing 34 where it moves alongscrew 42 as it rotates.Flange portion 51 extends throughlongitudinal opening 80 so that T-slots housing 34 to receiverail structure 55, bolts securing fencestructure coupling device 40, and bolts securingplate member 57 a, respectively. - The specific embodiments disclosed and illustrated herein should not be considered as limiting the scope of the invention. Numerous variations are possible without falling outside the scope of the appended claims. For example, the invention may be implemented in numerous different machine configurations with varying levels of automation. The invention may also be used to process many different kinds of materials including, but not limited to, wood, wood composites, polymeric materials such as PVC, polystyrene, polypropylene, polyethylene, fiberglass, textiles, etc. In addition to cutting, the invention may be used to carry out other processing steps such as bonding, sewing, heating, UV curing, painting or graphics application, etc. The subject matter of the invention includes all novel and nonobvious combinations and subcombinations of the various elements, features, functions, and/or properties disclosed herein.
